Description

  The present invention relates to a catalytic reaction apparatus in which, for example, a liquid and a gas are reacted using a finely divided catalyst.

Conventionally, in a catalytic reaction apparatus that uses a catalyst to react a liquid and a gas in a reactor to produce a liquid or a gas as a product, for example, the reactor is filled with gas from below to enter the reactor. There is one in which a reaction liquid and a catalyst are reacted with each other, and a product liquid and a product gas as reaction products are separated and discharged from above.
For example, in the catalytic reaction apparatus 100 including a gas-liquid solid three-phase shown in FIG. 10, a reaction liquid 103 in which a finely powdered catalyst 102 is dispersed is filled in a substantially capsule-shaped reactor 101, and above the liquid level. Are provided with a demister 104 that removes the mist of the liquid and catalyst scattered by the louver type, and a cyclone 105 that captures the scattered liquid and catalyst by centrifugal force, and finally only the product gas and the remaining unreacted raw material gas are at the upper end. Will be discharged through the pipeline.

A source gas supply pipe 107 is provided below the reactor 101, and bubbles 108 of the source gas are discharged from the nozzle 107 a into the reaction solution 103. As a result, a gas-liquid solid three-phase slurry is formed in the reactor 101.
In addition, a cylindrical fine wire mesh filter 109 that prevents the catalyst 102 from flowing out is provided in the vicinity of the liquid surface of the reaction solution 103, and the liquid 110 as a reaction product is separated from the catalyst from the wire mesh filter 109, and the reactor 101. Is discharged outside. The discharged product liquid 110 is conveyed to an external gas-liquid separation device 112 via a pipe line, and a gas containing unreacted raw material dissolved in the product liquid 110 is separated and expelled by a heater 113 to contain unreacted raw material. The product liquid 110 from which the gas has been separated is discharged to the other.

  In such a catalytic reaction apparatus 100, when the reaction product liquid 110 is discharged from the reactor 101, the fine catalyst 102 dispersed in the liquid 110 through the wire mesh filter 109 also flows out together with the liquid. There was a problem. Further, in the reactor 110, the catalyst 102 is gravity settled, so that the concentration of the catalyst 102 in the liquid is thin above the reactor 101 and tends to be thick below, so that the reaction above the reactor 101 It was difficult to proceed.

As one means for solving these problems, it is necessary to keep the finely divided catalyst 102 from flowing out of the reactor 101 together with the liquid 110 so as not to settle. When the catalyst 102 is fixed and held in the reactor 101, it is possible to fill the catalyst pellets having a certain size or more instead of the finely divided catalyst, or to fill the catalyst in a honeycomb shape. It was broken.
Further, when the catalyst 102 is not fixed in the reactor 101, in order to achieve uniform and highly efficient reaction conditions, the reaction gas is bubbled to form a gas-liquid two-phase flow. The reaction liquid 103 flows by bubble buoyancy, and the catalyst is flowed by the flow of the liquid to achieve uniform dispersion, or a fluidized bed for flowing the fine catalyst 102 by the direct gas flow is provided, or depending on the force of the gas Instead, the liquid was mixed and flowed with a stirrer or a pump to uniformly disperse the catalyst.

On the other hand, technologies described in Patent Documents 1 to 4 below have been proposed as magnetic separation filter devices. In these magnetic separation filter devices, for example, metal powder or the like mixed in hydraulic oil such as hydraulic equipment is removed as a contaminant that causes malfunction or failure. In this hydraulic oil purifier, a mesh container is filled with a filter member made of a wire made of an amorphous metal material, and magnetism generating means is disposed around the mesh container so that a magnetic field is applied to the mesh container. The working oil containing the metal powder is circulated in the metal so that the metal powder, which is a ferromagnetic material, is adsorbed and removed by the magnetized filter member.
These techniques are merely to adsorb a ferromagnetic substance contained in a fluid such as hydraulic oil with a magnetized filter member.

By the way, in the catalyst reaction apparatus 100 described above, when the catalyst 102 is fixed by the reactor 101 as described above, the particulate catalyst 102 cannot be used. Unlike conventional catalysts, there is a drawback that it requires labor and labor. Moreover, since the catalyst is in the form of a catalyst pellet or honeycomb, the reaction efficiency is low compared to that using a finely divided catalyst.
On the other hand, in the case where the catalyst is not fixed in the reactor 101, in any case, in order to prevent the finely divided catalyst from being settled by gravity and to uniformly disperse it in the liquid, a catalyst by gas or liquid is used. It was necessary to continue the flow and dispersion of the liquid during the reaction, and it was necessary to flow from below to above so that the flow of the fluid would be in the anti-gravity direction and to set the flow rate to a certain flow rate or higher. Therefore, as a result, there is a drawback in that it is restricted by the relationship between the flow rate condition of the fluid and the horizontal sectional area of the reactor.
Further, when liquid circulation by a pump is adopted as a means for promoting the mixing of the liquid in the reactor 101, the catalyst particles flow into the pump unless a catalyst outflow prevention means such as a fine wire mesh filter is provided on the suction side. The pump impeller that rotates at a high speed and the catalyst collide with each other to cause wear and wear of both, which is not desirable.

  In a catalytic reactor, it is necessary to perform a uniform reaction in order to react with high efficiency. For this purpose, it is necessary to disperse the fluid in the reactor as uniformly as possible using a finely divided catalyst. The flow conditions are likely to change significantly due to drift and changes in the flow pattern. As a result, the catalyst settles down, leading to a decrease in reaction rate, volumetric efficiency, and the like, possibly leading to catalyst deterioration. In particular, in the case of a bubble column composed of gas-liquid solid three phases, the relationship between the gas superficial velocity, gas hold-up, and flow pattern is complicated, and it is difficult to obtain a quantitative index and control is not easy.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a catalytic reaction apparatus capable of improving the efficiency of the catalytic reaction by adsorbing and holding the catalyst.

A catalytic reactor according to the present invention is a catalytic reactor in which a product is obtained using a finely divided catalyst in a reactor, and a catalyst holding unit is provided in the reactor, and the catalyst holding unit is provided in the reactor. A filled amorphous alloy wire, a magnetizing device provided on the outside of the reactor for applying a magnetic force to the amorphous alloy wire, and at least partly containing a ferromagnetic material, and the amorphous alloy wire being magnetized by the magnetic force of the magnetizing device And a catalyst adsorbed in a dispersed manner.
According to the catalytic reactor of the present invention, a magnetic field is generated in the reactor by the magnetizing device to magnetize the amorphous alloy fine wire, thereby uniformly dispersing and holding the catalyst containing the ferromagnetic material in the amorphous alloy fine wire. In this state, the reaction product can be obtained by reacting the fluid with the catalyst in the reactor.
For example, liquid, gas, or the like can be used as the fluid.

The catalytic reaction apparatus according to the present invention is characterized in that the catalyst holding unit described above is provided on the upper side of the reactor.
According to the catalytic reaction apparatus of the present invention, when the reaction is caused by the fluid and the catalyst in the reactor, for example, even if the catalyst is caused to flow in the vertical direction together with the fluid, the catalyst is likely to fall by gravity sedimentation. The catalyst concentration tends to be lower at the lower side of the reactor and lower at the upper side. However, by providing a catalyst holding unit on the upper side of the reactor, a magnetic field is generated in the catalyst holding unit by the magnetizing device. Then, the amorphous alloy fine wire is magnetized in the catalyst holding part, and the catalyst containing the ferromagnetic material is uniformly dispersed and adsorbed and held on the upper side of the reactor. In this state, the fluid is reacted with the catalyst in the reaction. Since the upper side of the reactor can be maintained at a uniform catalyst concentration similarly to the lower side, the reaction of the fluid can be efficiently performed by the catalyst uniformly dispersed throughout the reactor. Rukoto can.
Alternatively, the reaction is carried out between the fluid and the catalyst on the lower side of the reactor, and the reaction product gas and the remaining unreacted raw material both circulate above the reactor. Since the unreacted raw material can be uniformly reacted by the catalyst held by adsorption and held by the amorphous alloy fine wire magnetized by the magnetic field generated by the magnetizing device in the catalyst holding unit, more reaction can proceed. While obtaining many reaction products, discharge of unreacted raw materials can be suppressed.

The catalytic reactor according to the present invention is a catalytic reactor in which a product is obtained using a finely divided catalyst in the first reactor and the second reactor, and the second reaction is provided downstream of the first reactor. And a catalyst holding part is provided in the second reactor. The catalyst holding part is provided on the amorphous alloy fine wire provided outside the second reactor and the amorphous alloy fine wire filled in the second reactor. A magnetizing device for applying a magnetic force, and a catalyst that includes at least a portion of a ferromagnetic material and is dispersed and adsorbed on an amorphous alloy fine wire by the magnetic force of the magnetizing device.
According to the catalytic reaction apparatus of the present invention, the reaction is caused by the fluid and the catalyst in the first reactor, and the fluid extracted from the downstream side of the first reactor is supplied to the second reactor. The fluid withdrawn from the first reactor contains unreacted raw material components. For example, the catalyst tends to fall due to gravity sedimentation in the first reactor. Since the concentration is high and the catalyst concentration tends to decrease on the upper side, sufficient reaction does not necessarily take place on the downstream side, and unreacted raw material components flow out with much fluid extracted as reaction products. There can be. In such a case, the catalyst holding unit is provided in the second reactor provided on the path of the extracted fluid, and the catalyst containing the ferromagnetic material is uniformly dispersed in the amorphous alloy thin wire by the magnetizing device in the catalyst holding unit. As a result, the raw material components such as the liquid and gas accompanying the reaction product and the gas dissolved in the liquid react efficiently with the catalyst uniformly dispersed in the second reactor, and the reaction product is Can be obtained. As a result, it is possible to prevent the unreacted raw material components from being discharged and lost. In addition, a finely divided catalyst is accompanied by a liquid-solid slurry state on the liquid side of the extracted fluid, and a finely divided catalyst is accompanied with a mist-like liquid droplet on the gas side, but is provided on the path of the extracted fluid. By providing the catalyst holding part in the second reactor, since the catalyst contains a ferromagnetic material, the catalyst is trapped in the amorphous alloy fine wire by the magnetic adsorption force of the catalyst holding part, and the outflow of the catalyst can be prevented.
In addition, on the gas side, the packed layer of the amorphous alloy fine wire filled in the catalyst holding part provides a mist collecting action, so that it is possible to prevent the mist-like liquid droplets from flowing out.
In addition, you may provide a catalyst holding | maintenance part not only in a 2nd reactor but in a 1st reactor, and in this case, reaction efficiency improves further.

The catalyst holding part is partitioned by a cylindrical tube made of a nonmagnetic metal of the reactor or the second reactor, two partition plates that partition the cross section perpendicular to the axis of the cylindrical tube, and two partition plates. It is preferable that a first region filled with the amorphous alloy fine wire and a magnetizing device disposed in an outer portion of the tubular tube in the first region are provided.
In the catalyst holding unit, a magnetic field is generated by the magnetizing device in the first region partitioned by the partition plate by the magnetizing device disposed outside the first region, and almost no magnetic flux is generated outside the first region. Therefore, the amorphous alloy fine wire can be efficiently magnetized and the catalyst can be strongly adsorbed and held in a dispersed state.

In addition, a temperature adjusting heat medium flow path is provided in the second region partitioned by the first region of the cylindrical tube and the partition plate, and the reaction temperature of the fluid and the catalyst in the first region using the partition plate as a heat transfer member. May be adjusted.
Depending on the reaction temperature suitable for the reaction between the catalyst and the fluid in the first region, the reaction of the fluid and the catalyst in the first region through the partition plate by arranging the flow path of the temperature adjusting heat medium in the second region. The temperature can be adjusted by raising the temperature or cooling to a more suitable temperature.

The catalyst holding unit includes a cylindrical tube made of a non-magnetic metal of the reactor or the second reactor, an even number of four or more partition plates that partition the axial orthogonal section of the cylindrical tube, and two each Amorphous alloy thin wires are housed in a plurality of first regions partitioned by a partition plate, and a magnetizing device disposed on the outer portion of the tubular tube in the first region is provided, and alternately with the first region via the partition plate A second region may be provided, and a temperature adjusting heat medium flow path may be provided in the second region to adjust the reaction temperature between the fluid and the catalyst in the first region using the partition plate as a heat transfer member.
According to the present invention, the first region in which the catalyst holding portion is filled with the amorphous alloy fine wires by the even number of partition plates provided in the cylindrical tube to uniformly distribute and hold the catalyst, and the fluid flowing therethrough reacts. Since the second region in which the flow path of the temperature adjusting medium is arranged can be alternately provided, the reaction temperature of the fluid and the catalyst in the plurality of first regions can be adjusted to a temperature preferable for the reaction as a whole.

The magnetizing device may be configured to switch between generation and extinction of magnetic force.
When the catalyst is uniformly dispersed and adsorbed, a magnetic force is generated in the catalyst holding unit by the magnetizing device, and when the catalyst is removed, the magnetic force of the catalyst holding unit is extinguished by separating the magnetizing device. When a permanent magnet is used for the magnetizing device, the opening / closing drive means can switch the permanent magnet between a position facing the catalyst holding portion and a position separated from the catalyst holding portion. When an electromagnet is used, the current is turned on. , OFF to switch.

A plurality of second reactors are provided in parallel, and the first reactor and one of the second reactors are selectively connected to demagnetize the magnetic force generated by the magnetizing device of the other second reactor. May be.
In this case, the unreacted raw material component and the finely divided catalyst are supplied to the fluid extracted from the first reactor and supplied to the second reactor. The reaction raw material component is reacted with the catalyst, and during this time, the magnetic force of the catalyst holding part of the other second reactor is extinguished, and the treatment such as back washing and repair can be performed. In particular, if the catalyst adsorbed and collected in the catalyst holding part of the second reactor is returned to the first reactor by backwashing in a state where the magnetic force has been extinguished, the second reactor can be used alternately. It is possible to collect and reversely transfer the catalyst that continuously flows out from one reactor, and continuously promote the reaction of unreacted raw material components while preventing clogging, thereby preventing loss of raw material components and catalyst. .

In the catalytic reaction apparatus according to the present invention, a plurality of second reactors are connected in series, and the connection of the second reactor on the most upstream side is removed from the flow path and connected to the most downstream side after washing or processing. It may be used in this way.
Even if unreacted raw material components and fine catalyst accompany the fluid extracted from the first reactor, the fluid is sequentially supplied to a plurality of second reactors connected in series and held in the catalyst holding section. The reaction treatment of the formed catalyst and the unreacted raw material component is sequentially performed, and the catalyst containing the ferromagnetic material is adsorbed and collected on the amorphous alloy fine wire by the magnetic force. At that time, the second reactor on the most upstream side is periodically disconnected from the flow path in advance and connected in series to the most downstream side after the backwash process, thereby adsorbing and capturing the catalyst at the catalyst holding part of the second reactor. The collected and accumulated catalyst can be removed by backwashing with the magnetic force extinguished as appropriate, and can be continuously used for the reaction treatment while preventing clogging.

Further, in the catalytic reaction apparatus according to the present invention, a plurality of the above-described reactors each provided with the catalyst holding unit are connected in series, and the connection of the most upstream reactor is removed from the flow path to extinguish the magnetic force. You may make it connect with the most downstream after washing | cleaning or processing in a state.
Even in this case, even if an unreacted raw material component or a particulate catalyst accompanies the fluid extracted from the first reactor, the fluid is supplied to the next reactor connected in series, and the unreacted raw material component is supplied. In this case, the reaction process with the catalyst in the catalyst holding part is sequentially performed, and the finely divided catalyst is adsorbed and collected in the catalyst holding part. After washing or processing in the extinguished state, a magnetic force is generated again and connected to the most downstream side in series, so that the reactor containing the catalyst holding part is backwashed while preventing clogging and continuously reacting. Can be used for

According to the catalyst reaction apparatus of the present invention, the catalyst can be adsorbed and held on the amorphous alloy fine wire of the catalyst holding part by the magnetic force of the magnetizing apparatus, and the catalyst can be evenly distributed without depending on the flow of fluid such as liquid or gas. Reaction efficiency can be improved by achieving excellent dispersion retention.
In addition, the reactor having the catalyst holding part of the present invention does not depend on the mixing state in the flow direction of fluid such as liquid or gas, and thus can be designed as, for example, a piston flow type reactor, which improves the volumetric efficiency of the reaction amount. The amount of reaction products produced can be increased and the loss of unreacted raw materials is reduced.
Moreover, since the particulate catalyst accompanying the extracted fluid passes through the catalyst holding part and is dispersed and fixed by adsorption collection and does not flow out, it is necessary to provide another catalyst filtering device and return device in the fluid outflow path. In addition, since the catalyst is adsorbed and held by magnetic force, the spatial concentration of the catalyst can be set high. Furthermore, adsorption / collection / fixing / holding and removal / backwashing / removing of the catalyst can be easily performed by switching the magnetic force on and off by the magnetizing device.

  In addition, since the catalyst reaction apparatus according to the present invention includes the above-described catalyst holding unit on the upper side of the reactor, the unreacted raw material and the catalyst are dispersed by the catalyst uniformly dispersed throughout the entire surface including the upper side of the reactor. The reaction product can be efficiently performed, the reaction product can be obtained in a high yield, and unreacted raw material components such as gas and the particulate catalyst are discharged from the upper end of the reactor and lost. Can be suppressed.

  In addition, since the catalyst reaction apparatus according to the present invention is provided with the catalyst holding unit in the second reactor connected to the downstream side of the first reactor, the unreacted raw material accompanying the extracted fluid such as the reaction product in the first reactor. The components and the finely divided catalyst can efficiently react with the catalyst uniformly dispersed in the catalyst holding part of the second reactor to obtain a reaction product, and the finely divided catalyst can be adsorbed and collected. It can suppress that the reaction raw material component and the particulate catalyst are discharged and lost.

  In addition, the catalyst holding unit is provided with a first region and a magnetizing device, which are partitioned by two partition plates and filled with amorphous alloy fine wires in a cylindrical tube made of a nonmagnetic metal of the reactor or the second reactor. Therefore, in the catalyst holding part, a magnetic field is generated by the magnetizing device in the first region, and almost no magnetic flux is generated outside the first region, so that the amorphous alloy fine wire can be efficiently magnetized and the catalyst can be strongly dispersed in a dispersed state. Adsorption can be held.

  In addition, since the flow path for the temperature adjusting heat medium is provided in the second region of the cylindrical tube, the reaction temperature of the fluid and the catalyst in the first region is heated or cooled to a more suitable one via the partition plate. Can be adjusted.

  Further, the catalyst holding unit adjusts the reaction temperature by alternately providing a plurality of first regions and second regions in which the flow passages of the temperature control heat medium are arranged via an even number of partition plates. The reaction temperature of the fluid and the catalyst in one region can be adjusted more efficiently to a temperature preferable for the reaction.

  In addition, since the magnetizing device can switch between generation and extinction of the magnetic force, when the catalyst is uniformly dispersed and adsorbed, the magnetizing device generates the magnetic force, and when removing the catalyst, the magnetizing device extinguishes the magnetic force. be able to.

  Also, a plurality of second reactors are provided in parallel so that the first reactor and either one of the second reactors are selectively connected, and the magnetic force generated by the magnetizing device of the other second reactor is demagnetized. Therefore, any of the second reactors can be alternately used to prevent clogging and promote the reaction of the fluid.

  Further, in the catalytic reaction apparatus according to the present invention, a plurality of second reactors are connected in series, and the connection of the second reactor on the most upstream side is appropriately removed from the flow path so that the magnetic force is extinguished. After the treatment, the magnetic force is generated again to connect to the most downstream side, so that it can be continuously used for the reaction treatment while preventing clogging while washing.

  Further, the catalytic reactor according to the present invention removes the connection of the reactor on the most upstream side of the reactor equipped with the catalyst holding part from the flow path, and after washing or processing in a state where the magnetic force is extinguished, the magnetic force is again applied. Since it is generated and connected to the most downstream side, it can be used continuously for the reaction treatment while preventing clogging while washing the reactor including the catalyst holding portion.

Hereinafter, a catalytic reaction apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.
1 to 3 show a catalytic reaction apparatus 1 according to a first embodiment of the present invention.
The catalytic reaction apparatus 1 according to the first embodiment shown in FIG. 1 and FIG. 2 is a nonmagnetic metal partition made up of, for example, a pair of substantially parallel plates inside a substantially cylindrical first reactor 2 arranged in the vertical direction. The plate 3 extends downward from the upper side. The first reactor 2 is formed, for example, in a substantially capsule shape, its lower end surface 2 a forms a substantially hemispherical concave curved surface below the partition plate 3, and its upper end surface 2 b is approximately hemispheric above the partition plate 3. A concave curved surface is formed. Further, the first reactor 2 is provided with a catalyst holding unit 20, which will be described later.
The first reactor 2 is made of, for example, a nonmagnetic metal made of SUS piping, has a substantially capsule shape so as to withstand high pressure, and is made of a thick tube such as sch80.
In the first reactor 2 shown in FIG. 1 of the present embodiment, the reaction liquid 10 flows from the lower side to the upper side by the raw material gas 11, and the lower side is referred to as the upstream side and the upper side is referred to as the downstream side. The same applies to other embodiments.

And in the 1st reactor 2, a pair of partition plate 3 is provided in the height direction center area | region. In the first reactor 2 shown in FIG. 2, the first region partitioned by the pair of partition plates 3 and the arcuate portion 2 c on the peripheral side surface of the first reactor 2 is an inner region 4, and the inner region 4 is horizontal. The cross-section is substantially oval. Further, a pair of substantially arc-shaped second regions provided on both sides of the inner region 4 with the partition plates 3 interposed therebetween are defined as outer regions 5. The inner region 4 and the outer region 5 are partitioned so that fluids do not circulate within a range where the partition plate 3 is provided. The ratio of the sum of the horizontal cross-sectional areas of the two outer regions 5 to the horizontal cross-sectional area of the inner region 4 is in the range of 1: 5 to 1: 100.
In the inner region 4 of the first reactor 2, a pair of support fittings 8 a and 8 b made of a grating formed of a nonmagnetic metal such as stainless steel are disposed above and below the first region 2. The inner region 4 sandwiched between the two partition plates 3 between the support fittings 8a and 8b is filled with an amorphous alloy fine wire 9 having a high magnetic permeability and little residual magnetism. The amorphous alloy thin wire 9 is, for example, an irregular ribbon of an elongated ribbon, which is formed into a crumpled shape, and is filled in the entire volume partitioned between the upper and lower support fittings 8a and 8b and the pair of partition plates 3.

A reaction liquid 10 that is one reaction fluid is accommodated in the first reactor 2, and a raw material gas 11 that is the other reaction fluid is dispersed in the reaction liquid 10 as bubbles. Yes. Therefore, the reaction liquid 10 and the raw material gas 11 become a gas-liquid two-phase fluid and are filled in the inner region 4 of the first reactor 2 and the portion up to the lower end 2a thereof, and the liquid surface is the upper support fitting. It is the upper side of 8a.
Further, the pair of outer regions 5 are partitioned liquid-tightly from the reaction liquid 10 by the partition plate 3 and the upper and lower support fittings 8a and 8b. For example, a temperature control heat medium circulates from an external pipe (not shown). Thus, it is separated from the reaction solution 10 in the inner region 4 in a liquid-tight manner. For example, by circulating cooling water or hot water in the outer region 5, the reaction rate can be adjusted by removing heat from the reaction liquid 10 or heating through the partition plate 3.

Further, a supply pipe 13 for supplying the raw material gas 11 is inserted below the inner region 4 in the first reactor 2, and the raw material gas 11 becomes bubbles from the discharge port 13 a provided in the supply pipe 13. The reaction liquid 10 is agitated by being discharged into the inner region 4 in one reactor 2.
Further, in the first reactor 2, a drainage pipe 15 is provided on the upper side of the support fitting 8 a to extract the liquid 14 as a product after the reaction liquid 10 and the raw material gas 11 have reacted. In this extracted liquid 14, the unreacted raw material gas 11 is mixed as a dissolved state or bubbles. A discharge pipe 17 through which the exhaust gas 16 is extracted to the outside is attached to the upper end surface 2 b of the first reactor 2. The exhaust gas 16 is mixed with unreacted raw material gas 11 and gas generated by the reaction.

  In the inner region 4 in the first reactor 2, the fine particles of the catalyst 19 adsorbed and held by the magnetic alloy wire 9 together with the amorphous alloy wire 9 are present in a dispersed state. The catalyst 19 contains a ferromagnetic element such as iron, cobalt, or nickel as at least a part of the catalyst element. The catalyst 19 exists throughout the inner region 4 partitioned by the partition plate 3 and is in overall contact with the reaction solution 10.

Next, the magnetizing device 21 will be described with reference to FIG.
In the first reactor 2, the magnetizing device 21 is provided with a pair of permanent magnets 22 at opposing positions outside the inner region 4, and these pair of permanent magnets 22 are outside the first reactor 2. They are connected by a yoke 23 constituting a return path.
In the magnetizing apparatus 21, a uniform and high magnetic field is formed in the inner region 4 by the permanent magnets 22 respectively disposed on both sides of the inner region 4, and between the two permanent magnets 22, the yoke 23, and the inner region 4. A closed magnetic circuit is formed. In addition, since the outer area | region 5 partitioned off with the partition plate 3 remove | deviates from a magnetic circuit, magnetic flux hardly passes. A magnetic gradient is formed in the amorphous alloy thin wire 9 by the magnetic field in the inner region 4 of the first reactor 2, whereby the catalyst 19 containing a ferromagnetic material is adsorbed and held on the surface of the amorphous alloy thin wire 9.
Here, in the first reactor 2, the inner region 4 in which the amorphous alloy fine wire 9 is filled inside the cylindrical tube portion of the first reactor 2 and sandwiched between the support fittings 8 a and 8 b and the partition plate 3; A configuration including a pair of permanent magnets 22 provided outside the first reactor 2 with respect to the inner region 4 is referred to as a catalyst holding unit 20.

The pair of permanent magnets 22 and the yoke 23 selectively selects a magnetizing position (see FIG. 2) facing the first reactor 2 and a demagnetizing position where the permanent magnet 22 and the yoke 23 are separated from the first reactor 2. Opening / closing drive means 24 for controlling the operation is provided so as to be available.
The opening / closing drive means 24 guides the movement of the permanent magnet 22 and the yoke 23, guide rods 25, rods 26 connected to, for example, the central portions of the substantially semicircular yokes 23, and expands and contracts the rods 26. An air cylinder 27 is provided. The rod 26 expands and contracts when the air cylinder 27 is turned on and off, so that the permanent magnet 22 provided on the yoke 23 is positioned between the magnetized position facing the inner region 4 of the first reactor 2 and the demagnetized position spaced apart. It can be moved.

The catalytic reaction apparatus 1 according to the present embodiment has the above-described configuration. Next, a reaction method of the reaction liquid 10 and the raw material gas 11 by the catalytic reaction apparatus 1 will be described.
In FIG. 1 and FIG. 2, a pair of permanent magnets 22 provided on the yoke 23 by the opening / closing drive means 24 are provided at positions facing the inner region 4 of the first reactor 2. In this state, in the catalyst holding unit 20 provided in the center region in the longitudinal direction of the first reactor 2, a strong magnetic field is uniformly generated in the inner region 4 of the first reactor 2 located between the pair of permanent magnets 22. For example, a squirrel-shaped amorphous alloy fine wire 9 filled in the inner region 4 is magnetized.
As a result, the finely divided catalyst 19 dispersed and mixed in the reaction solution 10 is adsorbed and held by the magnetic gradient generated in the amorphous alloy fine wire 9 in the ferromagnetic part. Therefore, even if the reaction liquid 10 is not stirred and the flow of the reaction liquid 10 is not relied upon, the finely divided catalyst 19 is adsorbed and held in a substantially uniformly dispersed state on the amorphous alloy fine wire 9, and the catalyst 19 settles down due to its gravity. Can be suppressed.

In this state, the raw material gas 11 is discharged as bubbles from the discharge port 13a of the supply pipe 13 inserted on the lower end 2a side of the first reactor 2. The bubble-like source gas 11 discharged into the reaction liquid 10 can rise and flow into the inner region 4 to stir the reaction liquid 10. 1 and 2, the reaction liquid 10 filled in the inner region 4 of the catalyst holding unit 20 is filled with the amorphous alloy thin wire 9 between the upper and lower support fittings 8a and 8b. Bubbles are dispersed, and finely divided catalyst 19 is adsorbed and held on the surface of amorphous alloy fine wire 9 in a dispersed state.
Since the catalyst 19 is substantially uniformly dispersed and adsorbed and held on the amorphous alloy thin wire 9 in the inner region 4 by the strong magnetic field of the permanent magnet 22 in the magnetizing device 21, the catalyst 19 is reacted with the reaction solution 10 and the raw material gas 11. Promote the reaction.
In the outer region 5, almost no magnetic field is generated by the permanent magnet 15.

Then, the reaction liquid 10 and the raw material gas 11 are subjected to a catalytic reaction in the inner region 4 to generate a liquid 14 containing a reaction product, and is discharged to the outside by a drain pipe 15 provided on the upper side of the inner region 4. A small amount of unreacted source gas 11 remains in the liquid 14, but the amount of unreacted source gas 11 is reduced as compared with the case where the catalyst holding unit 20 according to the present embodiment is not provided. Further, the unreacted raw material gas 11 that has flowed out of the first reactor 2 from the reaction solution 10 is discharged to the outside as a discharge gas 16 from the discharge pipe 17 of the upper end 2b together with the product gas.
At this time, since the catalyst 19 is adsorbed and held by the amorphous alloy thin wire 9, it is possible to suppress the catalyst 19 from flowing out along with the liquid 14 containing the reaction product. Therefore, it is possible to prevent the catalyst 19 in the first reactor 2 from decreasing and prevent the reaction efficiency from decreasing.

As described above, according to the catalyst reaction apparatus 1 according to the present embodiment, the catalyst 19 is fixedly held on the amorphous alloy thin wire 9 by magnetic force in the catalyst holding unit 20 provided in the central region of the first reactor 2. Even if the fluid such as the reaction liquid 10 and the raw material gas 11 is not flowed or stirred, the uniform dispersion of the fine catalyst 19 is achieved, and the reaction of the reaction liquid 10 and the raw material gas 11 is sufficiently performed. Can promote. Specifically, the flow conditions of the reaction solution 10 and the particle size / specific gravity of the catalyst 19 are not restricted, and the physical properties such as the particle diameter of the catalyst 19 and the flow conditions do not need to be adjusted.
Moreover, since the reaction of the reaction liquid 10 and the raw material gas 11 does not depend on the mixed state in the flow direction of the reaction liquid 10 and the raw material gas 11 or the like, for example, it can be designed as a piston flow reactor, and the volumetric reaction efficiency is improved. The proportion of the reaction product produced can be increased, and the outflow loss of unreacted raw material components can be reduced.

Moreover, since the catalyst 19 is dispersed and held in the amorphous alloy fine wire 9 in the liquid, the catalyst 19 does not flow out together with the liquid 14 containing the reaction product from the drainage pipe 15 on the downstream side of the catalyst holding unit 20. The decrease of the catalyst 19 in the first reactor 2 can be suppressed, and the catalyst 19 is adsorbed and held by the amorphous alloy fine wire 9, so that the spatial concentration of the catalyst 19 can be set high. Moreover, it is not necessary to provide a device for filtering and separating and returning the catalyst 19 in the outflow path of the liquid 14 on the downstream side of the catalyst reaction unit 20.
Furthermore, the opening / closing drive means 24 can easily perform the adsorption collection / fixation holding / detachment / backwash removal of the catalyst 19 by switching the magnetic force of the magnetizing device 21 on and off.
Further, the amorphous alloy thin wire 9 has high thermal conductivity, and can efficiently diffuse the heat of the exothermic reaction on the adsorbing catalyst 19 so that temperature unevenness does not easily occur. Further, since the catalyst 19 is adsorbed and held on the surface of the amorphous alloy thin wire 9, the catalyst 19 does not settle due to insufficient flow of the reaction liquid 10 or the like, and conversely does not flow out of the drainage pipe 15 due to flow. Therefore, the reaction liquid 10 can be easily circulated by the pump, and the risk of damaging the catalyst 19 is small.
Further, for example, a temperature control heat medium such as cooling water circulates in the outer region 5 so that heat is exchanged with the reaction solution 10 in the inner region 4 to balance the reaction heat by heat removal or heating. The temperature of the adsorption holding unit is adjusted, and thereby the reaction rate can be adjusted to an appropriate range.

In addition, this invention is not limited to the structure of the catalyst reaction apparatus 1 by the above-mentioned embodiment, A suitable change, addition, etc. can be performed unless it deviates from the summary of this invention.
Next, other embodiments, modifications, and the like of the present invention will be described using the same reference numerals for the same or similar parts, members, and the like as in the first embodiment.

First, a catalytic reaction device 24 according to a modification of the first embodiment of the present invention will be described with reference to FIG.
In the catalytic reaction apparatus 24 shown in FIG. 4, the first reactor 23 is a capsule type, and has substantially the same configuration as the first reactor 2 in the first embodiment. The difference from the first reactor 2 is that the catalyst holding unit 20 is provided on the downstream side of the first reactor 23, that is, at an upper position close to the upper end 2b.
For this reason, in the first reactor 23 in the catalyst reaction device 24, the region from the lower end 2 a and the support fitting 8 a does not include a catalyst holding portion constituted by the magnetizing device 21 or the like, and the reaction liquid 10 by bubbling the raw material gas 11. Thus, the pre-reactor 25 is defined as a normal reaction zone in which the catalyst 19 flows to cause a reaction. The catalyst holding unit 20 having the same configuration as that of the first embodiment is provided on the downstream side of the preliminary reactor 25.

In the preliminary reactor 25, the reaction liquid 10 is filled inside, and the reaction liquid 10 contains a fine catalyst 19. Then, the bubble-like source gas 11 discharged from the discharge port 13a of the supply pipe 13 generates a bubble flow to cause a gas-liquid two-phase flow, whereby the reaction solution 10 flows upward to disperse the catalyst 19. To promote the reaction.
In this case, since the catalyst 19 in the reaction liquid 10 in the first reactor 23 is gravity-settled, the concentration of the catalyst 19 is small in the upper catalyst holding unit 20 and the concentration of the lower pre-reactor 25 is low. It tends to be thick. However, according to this modification, in the upper catalyst holding part 20 in the first reactor 23, the catalyst 19 can be adsorbed and held on the surface of the amorphous alloy fine wire 9 by the magnetizing device 21, so that the inside of the upper catalyst holding part 20 In this case, the spatial concentration of the catalyst 19 can be kept high.

  Therefore, according to the catalyst reaction device 24 according to this modification, the first reactor 23 maintains a state where there is no lean portion of the concentration of the catalyst 19 between the lower preliminary reactor 25 and the upper catalyst holding unit 20. Therefore, by reacting the raw material gas 11 with the catalyst in the reaction solution 10, a uniform and efficient reaction can be performed throughout.

Next, the catalytic reactor 27 according to the second embodiment of the present invention will be described with reference to FIG.
The catalyst reaction device 27 according to the second embodiment shown in FIG. 5 does not include the catalyst holding unit 20, and includes the first reactor 28 having the same configuration as the preliminary reactor 25 described above, and the first reactor. And a second reactor 30 connected to 28 drain pipes 15. Here, the 2nd reactor 30 is equipped with the substantially same structure as the 1st reactor 2 of the catalytic reaction apparatus 1 by 1st embodiment, and is equipped with the catalyst holder | retainer 20. FIG.
The first reactor 28 is formed in a substantially capsule shape, the reaction liquid 10 is accommodated therein, and the catalyst 19 is dispersed. In this case, the catalyst 19 also contains a ferromagnetic material at least partially. A supply pipe 13 for the source gas 11 is provided below the first reactor 28, and a discharge port 13a for discharging the source gas 11 as bubbles into the reaction liquid 10 and raising it in the vicinity of the lower end 2a. Yes. The reaction liquid 10 is caused to flow by the bubbles of the raw material gas 11 to disperse the catalyst 19.
On the upper side of the first reactor 28, a drain pipe 15 for discharging the liquid 14 after the reaction is attached at a position slightly lower than the liquid level of the reaction liquid 10, and the generated gas and the raw material gas 11 are attached to the upper end 2b. Is provided with a discharge pipe 17.
The drain pipe 15 is connected to the lower end 2 a of the second reactor 30, and the catalyst holding unit 20 is provided in the second reactor 30.

  In the catalytic reactor 27 according to the second embodiment, the raw material gas 11 is supplied from the supply pipe 13 in the first reactor 28, and the raw material gas 11 is contained in the reaction solution 10 containing finely divided catalyst 19 as bubbles. The reaction solution 11 is supplied with fluidity. In this situation, the reaction liquid 10 and the raw material gas 11 react with each other by the catalyst 19, but the catalyst 19 is gravity settled similarly to the above-described pre-reactor 25. On the upper side, the concentration of the catalyst 19 tends to be low.

Therefore, the liquid 14 after the reaction relatively contains the unreacted raw material gas 11 and the catalyst 19 is also extracted. Thus, the liquid 14 is supplied from the drainage pipe 15 to the second reactor 30. In the second reactor 30, the catalyst 19 is adsorbed and held by the catalyst holding unit 20 in a state of being uniformly dispersed on the surface of the amorphous alloy fine wire 9 magnetized by the magnetizing device 21.
Therefore, the unreacted raw material gas 11 and the reaction liquid 10 remain in the liquid 14 after reacting in the first reactor 28, but uniformly dispersed on the surface of the amorphous alloy thin wire 9 in the inner region 4 in the catalyst holding unit 20. Then, the reaction is further promoted by the adsorbed catalyst 19, and the unreacted raw material component remaining in the liquid 14 is surely reacted by catalytic reaction to further reduce or eliminate the remaining amount of the unreacted raw material component. Can do.
Further, since the amorphous alloy thin wire 9 in the inner region 4 has a magnetic gradient, the catalyst 19 accompanying the liquid is also adsorbed and collected by the amorphous alloy thin wire 9 to reduce the outflow of the catalyst 19 to the downstream, or Can be extinguished.

  Therefore, according to the catalytic reactor 27 according to the second embodiment, the reaction liquid 10 and the raw material gas 11 are reacted with the catalyst 19 in the conventional first reactor 28 in the previous stage, and the reaction liquid 10 and the raw material gas 11 are not dissolved in the generated liquid 14. Even if the reaction raw material component and the outflowing catalyst 19 are included, since the catalyst holding unit 20 that disperses and adsorbs the catalyst 19 in the second reactor 30 is provided in the subsequent stage, the unreacted raw material component contained in the liquid 14 is further reduced. The catalyst 19 can be efficiently reacted, and the catalyst 19 can be efficiently adsorbed and collected for reuse, and the unreacted raw material component in the liquid 14 after the reaction and the outflowing catalyst 19 can be further reduced or eliminated. Can do.

In the catalyst reaction device 27 according to the second embodiment described above, one second reactor 30 having the catalyst holding unit 20 is provided in the subsequent stage, but a plurality of (two in the figure are two as shown by a one-dot chain line) in FIG. ) Second reactor 30 may be provided in parallel, for example.
In this case, the plurality of second reactors 30 are switched by connecting the drainage pipe 14 to the lower end portion 2a on the side of supplying the liquid 14 and providing the switching valves 31a and 31b to switch the liquid 14 after the reaction to either You may make it supply to the 2nd reactor 30. FIG. In this case, the catalyst reaction is performed by holding the catalyst using the magnetizing device 21 in one second reactor 30 to which the drainage pipe 15 is connected, and the drainage pipe 15 is shut off in the other second reactor 30. In addition, the catalyst 19 can be removed from the amorphous alloy thin wire 9 by demagnetization of the magnetizing device 21 and backwashed. As described above, the switching valves 31a and 31b may be alternately switched for the two second reactors 30 to selectively perform the catalytic reaction and the washing. Alternatively, the catalytic reaction may be performed by holding the catalyst using the magnetizing device 21 simultaneously in the plurality of second reactors 30.

Next, a catalytic reaction device 32 according to a third embodiment of the present invention will be described with reference to FIG.
In the catalytic reaction apparatus 32 according to the third embodiment shown in FIG. 6, a first reactor 33 that does not include the catalyst holding unit 20 and a second reactor 34 that includes the catalyst holding unit 20 are integrally and serially connected. ing.
The first reactor 33 has substantially the same configuration as that of the first reactor 28 according to the second embodiment, and a second reactor 34 that is reduced in diameter by a tapered portion 35 and has a relatively small inner diameter is connected to an upper end portion thereof. Is provided. The first reactor 33 and the second reactor 34 are formed in a substantially capsule shape.

In the lower part of the first reactor 33, a supply pipe 13 for the source gas 11 is provided, and in the vicinity of the lower end 2a, a discharge port 13a for discharging the source gas 11 as bubbles into the reaction liquid 10 and raising it is provided. ing. The reaction liquid 10 is caused to flow by the bubbles of the raw material gas 11 to disperse the catalyst 19 and promote the reaction.
On the upper side of the first reactor 33, one or a plurality (two in the figure) of a wire mesh filter 37 having a cylindrical shape such as a substantially cylindrical shape is disposed at a position slightly lower than the liquid level in the reaction solution 10. The upper ends of these wire mesh filters 37 are connected to a drain pipe 15 for discharging the liquid 14 after reaction to the outside, and the catalyst 19 is discharged to the outside along with the liquid 14 after reaction by the wire mesh filter 37. Is preventing.

In the first reactor 33, when the unreacted raw material gas 11 flows upward from the liquid surface of the reaction solution 10 together with the gas generated by the reaction, the unreacted raw material gas 11 collects via the tapered portion 35. And is configured to flow into the second reactor 34. Further, the liquid mist of the reaction liquid 14 and the fine particulate catalyst 19 are also scattered as a droplet together with the reaction product gas and the unreacted raw material gas 11 and introduced together with the second reactor 34.
The second reactor 34 is provided with the above-described catalyst holding unit 20, and the amorphous alloy thin wire 9 filled in the inner region 4 makes the catalyst 19 uniform by the magnetic field of the pair of permanent magnets 22 of the magnetizing device 21. Adsorbed in a dispersed state. In the catalyst holding unit 20 of the second reactor 34, the reaction between the unreacted raw material gas 11 flowing from the first reactor 33 and the mist of the reaction liquid 10 is promoted by the dispersed and adsorbed catalyst 19, The fine catalyst that scatters is also adsorbed and collected on the surface of the amorphous alloy wire 9 by the magnetic gradient of the amorphous alloy wire 9, and the mist of the reaction solution 14 that scatters as a splash collides with the packed bed of the amorphous alloy wire 9. It is collected and dropped into the reactor 33 by gravity and returned. Further, the catalyst 19 adsorbed and held on the surface of the amorphous alloy fine wire 9 is appropriately detached and back-washed by demagnetizing the catalyst holding unit 20 and flowing a liquid from above, and dropped into the first reactor 33. Can be returned.

According to the catalytic reaction apparatus 32 according to the third embodiment, in the first reactor 33, the raw material gas 11 is discharged as bubbles into the reaction liquid 10 to cause an upward flow, whereby the catalyst 19 is reacted with the reaction liquid 10 and the raw material gas 11. It is diffused by flowing together. Then, the raw material gas 11 reacts with the reaction liquid 10 and the catalyst 19 in the first reactor 33, and the liquid 14 after the reaction is discharged from the drain pipe 15 through the wire mesh filter 37.
However, since the catalyst 19 has a tendency that the concentration on the upper side of the reaction solution 10 is thin and the concentration on the lower side tends to be thick due to gravity sedimentation, unreacted raw material components that cannot be reacted due to the concentration difference of the catalyst 19 remain. From above, the reaction product gas and the unreacted raw material gas flow out. Further, a part of the reaction liquid 10 is accompanied with the gas as mist, and the fine catalyst is ejected as droplets and rises with the outflow gas.
Unreacted components such as the raw material gas 11 passing through the first reactor 33 are reacted by the catalyst 19 introduced into the inner region 4 of the catalyst holding unit 20 and adsorbed and held, and the mist of the reaction liquid 10 is amorphous. It collides with the packed bed of the alloy fine wire 9 and is collected, falls to the reactor 33 by gravity and is returned, and the particles of the catalyst 19 are adsorbed and collected by the magnetic force of the catalyst holding unit. Thus, the raw material components such as the unreacted raw material gas 11 are reduced by the reaction by the catalyst, and the liquid mist and the catalyst are prevented from flowing out by the amorphous alloy fine wire 9, and as a result, from the upper end 34 a of the second reactor 34. Further, it is possible to suppress or prevent the unreacted raw material, liquid mist, and catalyst 19 from being lost to the outside and being lost.

 As described above, according to the catalytic reaction apparatus 32 according to the present embodiment, the raw material gas 11 reacts with the reaction liquid 10 and the catalyst 19 in the first reactor 33, and the liquid 14 after the reaction is discharged via the wire mesh filter 37. The unreacted raw material gas 11 discharged from the liquid pipe 14 to the outside and passed through the reaction liquid 14 and the mist of the reaction liquid 10 are sufficiently reacted by the catalyst holding unit 20 provided in the second reactor 34. Therefore, it is prevented that the unreacted raw material component is discharged outside. Moreover, the magnetic gradient of the catalyst holding unit 20 prevents the particulate catalyst accompanying the raw material gas 11 from being adsorbed and scattered and scattered outside.

Next, another configuration example of the catalyst holding unit 20 will be described as a fourth embodiment of the present invention.
The catalyst holding unit 40 provided in the first reactor 39 of the catalyst reaction apparatus 38 according to the fourth embodiment shown in FIG. 7 is a plurality of partition plates 3 made up of an even number in the first reactor 39 which is a substantially cylindrical housing. Here, four partition plates 3 are provided. As a result, two sets of inner regions 4 partitioned by two opposing partition plates 3 are formed, and three outer regions 5 are formed between and outside the two regions.
The two sets of inner regions 4 are filled with amorphous alloy fine wires 9, respectively. A pair of permanent magnets 22 is arranged outside the inner regions 4 as a magnetizing device 21 so as to face each other. These two sets of permanent magnets 22 are also provided with a pair of opening / closing drive means 24 (not shown) for moving the permanent magnets 22 so as to face and separate from the first reactor 39, respectively.

  Further, each inner region 4 is filled with the reaction liquid 10 containing the catalyst 19, and the raw material gas 11 is supplied as bubbles from the discharge port 13 a of the supply pipe 13 of the lower raw material gas 11. On the other hand, for example, cooling water circulates in the three outer regions 5 as temperature adjusting media through external pipes (not shown).

If the catalyst reaction device 38 is configured as described above, the magnetizing device 21 can set a stronger magnetic field by opposingly arranging the permanent magnets 22 in the relatively narrow inner region 4. Since the fine alloy wire 9 can be magnetized more strongly and the catalyst 19 can be uniformly dispersed and fixed, the reaction between the reaction solution 10, the raw material gas 11, and the catalyst 19 is performed more uniformly and strongly in the inner region 4, so The reaction raw material liquid 10 and the raw material gas 11 are further reduced, and these discharges can be further suppressed to improve the reaction efficiency.
The inner region 4 provided in the first reactor 39 is not limited to two and may be three or more. In any case, it is preferable to provide an even number of partition plates 3 to partition the inner region 4.

Next, as a fifth embodiment of the present invention, a configuration example of a combination of a plurality of reactors provided with a catalyst holding unit 20 will be described.
The catalyst reaction apparatus 41 shown in FIG. 8 will be described by taking the catalyst reaction apparatus 1 according to the first embodiment as an example. In the catalytic reaction device 41, the supply pipe 13 for the raw material gas 11 is connected to the lower end 2a so that the three first reactors 2 provided with the catalyst holding unit 20 are arranged in parallel, and the liquid 14 after the reaction is discharged. The drainage pipes 15 are connected to each other. Here, each 1st reactor 2 shall be distinguished by code | symbol 2A, 2B, 2C.
And it branches from each supply pipe | tube 13 connected to each 1st reactor 2, and it is comprised so that the discharge pipe 42 may be provided, respectively, and the liquid 14 after reaction may be discharged | emitted.
The pipes 13, 15 and 42 are provided with switching valves 43, 44 and 45 for opening and closing. When using the catalytic reaction device 41, two of the three first reactors 2 are connected in series and used, so the direction of the first reactor 2 is set upside down depending on the connection form.

A method of using the catalyst reaction apparatus 41 having such a configuration will be described with reference to FIG. 9 (a), (b), and (c), any two first reactors 2 are connected in series by switching the switching valves 43, 44, and 45, respectively, and the remaining one first reaction is performed. The container 2 is shown in a separated state.
In FIG. 9 (a), the first reactor 2C is shut off from the pipeline, demagnetized by turning off the magnetizing device 21, and the catalyst 19 is removed from the amorphous alloy thin wire 9, and maintenance such as repair or the like is performed. . For this reason, the two first reactors 2A, 2B are connected in series, and when the magnetizing device 21 is turned ON, the catalyst 19 is adsorbed in a dispersed state on the amorphous alloy thin wire 9 in each catalyst holding unit 20, and the tubes 13, 15 , 43, the raw material gas 11 is sequentially reacted with the reaction liquid 10 and the catalyst 19 in the first reactors 2A and 2B. As a result, the liquid 14 after the reaction can be discharged with almost no unreacted source gas 11 present.

Next, in FIG.9 (b), the 1st reactor 2A was interrupted | blocked from the pipe line, and the 1st reactor 2C which finished maintenances, such as washing | cleaning and repair replacement | exchange previously, was connected to the downstream of the 1st reactor 2B. In this state, the raw material gas 11 is supplied to the first reactors 2B and 2C to be reacted.
Next, in FIG.9 (c), the 1st reactor 2B was interrupted | blocked from the pipe line, and the 1st reactor 2A which finished the maintenances, such as washing | cleaning and repair replacement | exchange previously, was connected to the downstream of the 1st reactor 2C. In this state, the raw material gas 11 is supplied to the first reactors 2C and 2A to be reacted.
In this way, with respect to the plurality of first reactors 2, some of the first reactors 2 are shut off from the pipes to remove or wash the catalyst 19, and the remaining first reactors 2 use the catalyst holding unit. 20 is used to carry out the catalytic reaction, and the first reactor 2 that has been subjected to maintenance such as cleaning and repairing in turn is connected to the rearmost side, so that a plurality of second reactors can be produced without worrying about clogging or failure of the catalyst 19. One reactor 2 can be used continuously.

  In addition, in the catalyst reaction apparatus 41 by 5th embodiment mentioned above, it replaces with the 1st reactor 2 by 1st embodiment, the 1st reactor 23 of the catalyst reaction apparatus 41 by a modification, the catalyst holding | maintenance by 3rd embodiment The present invention can be applied to the first reactor 33 and the second reactor 34 of the unit 30, the first reactor 39 of the catalyst holding unit 38 according to the fourth embodiment, and the like. Moreover, also in the catalyst holding part 27 in 2nd embodiment, the 2nd reactor 30 can be arrange | positioned multiplely as shown in FIG. 9, and it can use similarly in series.

In each of the above-described embodiments, the first reactors 2, 23, 39 and the second reactors 30, 34 using the catalyst holding unit 20 are formed in a substantially cylindrical shape, so that the high-pressure and high-temperature reaction liquid 10 and the raw material gas are formed. 11 reaction can also be used.
However, as long as the reaction liquid 10 and the source gas 11 are not high pressure or high temperature, they are not limited to a substantially cylindrical shape, and may be a polygonal cylinder shape such as a square cylinder used in the prior art. In some cases, the partition plate 3 is not necessary and the outer region 5 does not need to be provided, so that the entire cross-sectional volume of the first reactor 2, 23, 39 or the second reactor 30, 34 is filled with the amorphous alloy thin wire 9. The catalyst 19 can be dispersed and adsorbed by the magnetizing device 21.
In addition, in the catalyst holding unit 20, the first cylindrical reactors 2, 23, 39 and the second reactors 30, 34, which are substantially cylindrical, are not provided with the partition plate 3, and the entire cross-sectional volume is filled with the amorphous alloy fine wire 9 to be permanent. The magnetizing device 21 may be used with the magnets 22 arranged opposite to each other.

  In each of the above-described embodiments and the like, the permanent magnet 22 is used as means for forming a magnetic field in the magnetizing device 21, but an electromagnet may be used instead of this, and in this case, the current is turned on and off. Since the magnetization and demagnetization can be switched, the opening / closing drive means 24 may not be provided.
