INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD This invention relates to a method for producing (4) a raw material mixture containing a hydrocarbon having a carbon number of 4 or more and a T-alcohol and a dimethyl group. [Prior Art] The method of B has been implemented as a raw material for the flow contact decomposition of petroleum brain or sputum, m-coating solution, and tartar-light oil. In recent years, it has been used as raw materials for ethylene and 2-butadiene. The metathesis reaction, the carbon number 4 is contact cracking of the fine hydrocarbons, and the oxygenation of the olefins such as methanol and diethyl ether and methanol is further modified:: '= knowing the method of carbon number hydrocarbons ( Patent Document... Production of a lower olefin as a raw material Patent Document 1: US Pat. No. 6,880,038 [Summary of the Invention] (Problems to be Solved by the Invention) Conventionally, many proposals have been made for the reaction and purification as a production of propylene. However, the off-hand-to-hand knife=the oxygen-containing compound such as an alcohol as the raw material has two ==: but it is not proposed to include a lower heart than the reactor. Therefore, the first object of the present invention is to carry out the process. It is used to make a novel and economical system with a carbon number of 4 or more, at least one of which is reacted to produce 7, and the other side of the methanol and the dihydrazyl bond is in the mainstream of the current ethylene and propionate manufacturing method. Vapor 312XP / invention manual (supplement) /97-01/96135332 200831453 In the cracking process, although the process of the present invention is not substantially changed, but the process of the present invention is lysed with the plug gas, the ratio of the fineness, m, , ..., the smock undressing is integrated, and the process can be changed. In addition, by integrating the effective use of the flow suspensions that are not required in the process of each other, it is possible to construct an efficient process with a more significant multiplication effect. It is to provide a novel and economical system, the system combines the process and steam cracking. η (the means to solve the problem) 3 Ming and others are aimed at making the carbon number 4 or more of the rare hydrocarbons, and methanol and dimethyl - The reaction was carried out to obtain the reaction of (4). "The result is that the following results are found: "Excessive amount of dilute hydrocarbons consumed by the reaction", and the secondary compound of the aromatic compound and the stone compound Significantly, on the other hand, if the decene is removed, the yield of propylene is too low. By appropriately setting the reaction conditions of temperature, i, partial pressure, space velocity, etc., the amount of olefin consumed is controlled to some Within a certain range, it can be selected according to high selectivity and high yield. When propylene is obtained under such conditions, since a large amount of olefin having 4 or more carbon atoms which can be used as a reaction raw material is contained in the reactor outlet stream, the compounds are recovered into the reactor. On the one hand, in the reaction of at least one of the olefin having a carbon number of 4 or more and at least one of methanol and dimethyl ether, a trace amount of an aromatic compound and paraffin are also formed, and are combined in the outlet fluid of the reactor, especially in use. When a dilute hydrocarbon raw material having a carbon number of 4 or more is used as a raw material of paraffin, the paraffin concentration in the outlet fluid of the reactor increases. Since the paraffin wax hardly reacts in the reactor, 312XP/Invention Manual (Supplement)/97- 01/96135332 200831453 Therefore, when it is recycled to the reactor together with the olefin having 4 or more carbon atoms, the stone butterfly in the system will be fine and accumulated. Therefore, it is preferred to remove a portion of the fluid containing the stone butterfly from the system. In this case, the fluid to be taken out is preferably made into a fluid which can be effectively utilized. In addition, when an aromatic compound having a specific concentration or more is present in the olefin fluid having a carbon number of 4 or more, the reaction of the aromatic compound with an olefin having 4 or more carbon atoms, and an aromatic compound with methanol and dimethyl The reaction of at least one of the ethers becomes remarkable, and it is unfavorable to unnecessarily consume the supplied olefin having at least 4 carbon atoms and at least two of methanol and dimethyl ether. Further, when the aromatic compound is supplied to the reactor, the catalyst generated by the reaction with the olefin having 4 or more carbon atoms is caused by the catalyst = pore blocking, thereby promoting catalyst deterioration. As far as possible, remove the aromatic compounds present in the reaction benefit outlet fluid from the system and recycle them to

Such solid acid catalysts are preferably those having molecular sieve effect, and preferably In the solid acid catalyst, the structure of zeolites and phosphoric acid having a molecular sieve effect, as indicated by the code defined by the International Zeolite Association (IZA), may be, for example, ruthenium or osmium.

OT/nm3 The catalyst, as such, preferably, for example, MFI, MEL, MOR, MWW, FAU, BEA, CHA, more preferably MFI, MEL, MOR, MWW, CHA, especially MFI, MEL, MWW, Here, the skeletal density (unit: T/nm3) means the number of T atoms (atoms other than oxygen in the atoms constituting the zeolite skeleton) present in the zeolite per unit volume (lnm3), and this value will be Further, as the solid acid catalyst, it is preferable to have fine pores having a pore diameter of 0·3 to 0·9 nm, and a BET specific surface area of 200 to 700 m 2 /g, and a pore volume of 0· : 1 to 0.5 g/ml of crystalline aluminosilicates, metal losili cates, or crystalline acid-filled ingots, etc. Here, the pore diameter is represented by International. The crystallographic free diameter of the channels defined by Zeolite • Association (IZA), when the pores (channels) are in the shape of a perfect circle, refer to the diameter of the pores in the shape of the pores 312XP / invention instructions (repair) ) /97-01/96135332 23 200831453 When it is elliptical, it means its short diameter. In addition, the aluminum silicate, the preferred system Si〇2 / Ah〇3 ι〇 the molar ratio or more. If the molar ratio of Si〇2/Al2〇3 is too low, the durability of the catalyst is lowered, which is not preferable. The upper limit of the Si〇2/Al2〇a molar ratio is usually 1 〇〇〇〇 - or less. If the Mo of Si/AhOs is higher than this, then the activity of the catalyst is lowered, no. The above molar ratio can be obtained by a method such as fluorescent ray irradiation and chemical analysis. r. The aluminum content in the catalyst can be controlled and controlled according to the amount of raw materials used to prepare the catalyst. In addition, after the preparation, the A1 can be reduced by steaming, etc. It can be replaced by other elements such as boron or gallium, and it is preferable to use it as a substitute. This catalyst can be used alone or in combination of two or more. The above-mentioned catalyst active ingredient can be directly used as a touch. In the reaction, the substance and the adhesive which are inert to the reaction may be used in the reaction, or the mixture may be formed into a mixture, or may be used in the reaction. As a substance and an adhesive which is responsive to the reaction, for example, oxidation may be employed. Aluminum or alumina gel, diacetate, dioxane (tetra) gel, quartz, and mixtures thereof, etc. The above-mentioned touch I composition does not contain substances inert to such reactions and adhesion agents. It has only the composition of the active ingredient of the catalyst. Therefore, in the case of the present invention, the active substance of the catalyst is reacted with the above-mentioned catalyst active ingredients in the case of a substance containing an inert substance and an adhesive. Inert materials such as shells and adhesives are called catalysts. In the case where there is no such thing as the shell and the adhesive, the catalyst active ingredient 312XP/invention specification (supplement)/97·〇1/1⁄2 135332 24 200831453 ^invented The catalyst active ingredient used = is measured by the diameter of the flat diameter. 1. When the two paths are too large, the catalyst activity is displayed, and the right catalyst is pulled, which is inferior. Small, the right is too small, the operability - etc. is obtained. The diameter of the flat diameter can be observed by SEM observation of the use of the touch of the sister of the invention is not particularly limited, Modulation is carried out by a known method for hydrothermal synthesis. :: It can also be modified by ions, or formed by the formation of ions, immersion and support. Further, the catalyst for the modification "in the case of the reaction" may have the above physical properties and composition, and may be prepared according to the formula (4). [Reaction raw materials] It is a hydrocarbon hydrocarbon as a reaction raw material in the present invention. Methanol and dimethyl ether are described. The above olefins (olefin raw materials) G - the use of olefins having a carbon number of 4 or more as a reaction, There is no limitation. For example, a hydrogen obtained by gasification of carbon can be produced by a producer (10) fraction, a C4 raffinate + a raffinate, etc., from a petroleum feedstock by contact decomposition or steam cracking. The /co mixed gas is synthesized as a raw material (1 sher-Tropsch), obtained by the oligomerization reaction containing ethylene, and desulfurized or oxidized by a cerium having a carbon number of 4 or more. Those obtained by the dehydrogenation method, those obtained by the reaction, those obtained by dehydration, those known by the chlorination reaction of a divalent compound having a carbon number of 4 or more, etc., which are obtained by various known methods ( In particular, 312XP/invention specification (supplement)/97-01/96135332 200831453 olefin having a carbon number of 4 to 10), in which case, a compound other than the olefin having 4 or more carbon atoms derived from each production method may be used as it is. The state of the art can also use refined olefins. Among them, when an olefin raw material containing a paraffin having a carbon number of 4 or more is used, since the paraffin has an effect of diluting a gas, it is easy to control the reaction temperature, and a paraffin-containing raw material can be obtained at a relatively low cost, which is preferable. More preferably, it is an olefin raw material containing at least one of n-butylene and isobutane. As such preferred raw materials, for example, the above-mentioned BB fraction, C4 raffinate D liquid-1 and C4 raffinate-2 can be mentioned. These materials usually contain butadiene. Since butadiene is easily converted into an aromatic compound by a reaction, it is very important that at least a part of the produced aromatic compound is not recovered in the reactor and taken out as in the present invention. Further, since the BB fraction contains a large amount of butadiene, it is preferred to use a fluid having a butadiene concentration as a raw material in contact with a hydrogenation catalyst. 1. The decyl alcohol, dimethyl ether >c; The source of the use of at least one of methanol and dimethyl ether as a reaction raw material is not particularly limited. For example, it can be obtained by a hydrogenation reaction of coal and natural gas, and a hydrogen/co mixed gas derived from by-products in the iron industry; a plant-derived alcohol is obtained by a modification reaction; Those who have obtained organic substances such as recycled plastics and municipal wastes. In this case, any one of a state in which a compound other than methanol or dimethyl ether from each production method is mixed may be used as it is, and a purified one may be used. [Reaction operation and conditions: Step (1) (lc) in the third aspect] Hereinafter, the 312XP/Mtft^# of the propylene of the present invention using the above catalyst and reaction raw material (ffim/97-〇l/) 96135332 26 200831453 The operation and conditions of the manufacturing method are explained. <Reactor> The reaction of '4 or more olefins with sterols and diterpene scales> is the gas phase reaction. The form of the gas phase reactor is not limited, and is usually selected from a continuous fixed bed reactor and a fluidized bed reaction, preferably a fixed bed reactor. Further, when the catalyst is filled into a fixed bed reactor, In order to suppress the temperature distribution of the n-touch layer to be small, the granular material which is inert to the reaction, such as quartz sand, alumina, emulsified cerium, cerium oxide-alumina, etc., may be mixed with the catalyst. In this case, the amount of the granular material which is inert to the reaction such as quartz sand is not particularly limited. Further, from the viewpoint of uniform mixing with the catalyst, the granular material is preferably bonded. The catalyst has the same degree of particle size. In addition, the reaction can also be connected by series. Two or more reaction units are formed. In this case, one reactor may be partitioned into a plurality of reaction chambers, or two or more reactors may be connected in series. ^ " When the above reactors are connected in series, a heat exchanger may be disposed between the reactor and the reactor for the purpose of removing heat generated by the reaction. Further, the purpose of dispersing heat may be The reaction substrate (reaction raw material) is divided and supplied. Preferably, at least one of methanol and dimercaptopurine is divided into a reaction portion (reactor or reaction chamber) of the first stage and a reaction unit after the second stage (reaction) In the reaction conditions used in the present invention, the catalytic carbon is less, and the catalyst 312XP/invention specification (supplement)/97-01/96135332 27 200831453 has a slow deterioration rate, but In the case of continuous operation for more than one year, it is necessary to carry out catalyst regeneration during operation. For example, when selecting a solid-state reactor, it is preferable to set at least two or more reactors in parallel while switching the reaction and regeneration. While operating as a fixed bed reactor, it is selected from a multi-tubular reactor or a heat-dissipating reactor. On the other hand, in the case of a remote selective fluidized bed reactor, it is preferred to continuously contact the catalyst. The catalyst is sent to the regeneration tank, and the catalyst regenerated in the regeneration tank is continuously sent back to the reactor for reaction. Here, as the catalyst regeneration operation, for example, a catalyst which deteriorates due to carbon deposition may be mentioned. The regeneration is carried out by treatment with a nitrogen gas containing oxygen and steam, etc. As a regeneration operation in the fixed bed reactor, it is preferred to remove the volatile organic compound attached to the catalyst by using a nitrogen gas to contain The low-concentration oxygen nitrogen gas is burned and removed, and then treated with a gas to remove the molecular oxygen contained in the catalyst layer. f <concentration ratio of olefin to decanol and dimethyl ether supplied to the reactor> In the present invention, the amount of olefins having a carbon number of 4 or more supplied to the reactor is relative to the methanol supplied to the reactor The total number of ears and the number of diterpene groups is 2 times, and the molar ratio is 〇·2 or more, preferably 〇·% or more, and is 10 or less, preferably 5 or less. · ' 312XP / Invention Manual (Repair) / 97-01/96135332 28 200831453 When Mdm is set, Mc4 is 0· 2~10 times (Mm+2Mdm), preferably 0 times, regardless of the supply concentration ratio is too low or The over-south's reaction is slower and slower, especially 疋. If the ratio of the supply to the right is too low, the consumption of raw materials will be reduced, so it is not good. Here, the supply concentration ratio can be known by quantifying the composition of the fluid supplied to the reactor or the mixed fluid by a general analytical method such as gas chromatography. Further, when at least one of the olefin having 4 or more carbon atoms and methanol and dimethyl ether is supplied to the reactor, these may be supplied separately, or a part or all of them may be mixed beforehand and supplied. <Base concentration to be supplied to the reactor> In the present invention, the total concentration (base concentration) of the olefin having a carbon number of 4 or more and methanol and dimethyl ether in the total supply raw material supplied to the reactor is preferably 20 volumes. More than or equal to 80% by volume, more preferably 3% by volume or more and 7% by volume or less. The basis of this can be determined by quantifying the composition of the fluid supplied to the reactor or the composition of the mixed fluid by a general analytical method such as gas chromatography. When the concentration of the matrix on the right is too high, the formation of the aromatic oxime and the paraffin wax becomes remarkable, and the selectivity of propylene decreases, and the tendency of "low" tends. On the contrary, if the base is When the Bayer wave is too low, the reaction speed becomes 愣〇^^^H^ Γ and then a large amount of catalyst is required, and the refining cost of the product and the magical construction fee of the reaction device 1 are also increased, and it is not economical. 312ΧΡ/发明发明(补件)/97-〇1/96135332 200831453 In the present invention, the reaction substrate is diluted as a method for controlling the concentration of the substrate by using a diluent gas as described below, for example, control is carried out.

The diene concentration of the total feedstock of the reactor was 2.0 v/min. If the raw materials in the raw materials are smack, 麄一^, and "TT j a cloth/times pass, the formation of aromatic compounds will increase, and the deterioration caused by the carbon deposition of the catalyst will become faster. Preferably, the butylene/Chen degree system can be obtained by quantifying the composition of the fluid supplied to the reactor or the mixed fluid by a general analytical method such as gas chromatography. The method of reducing the concentration of butadiene in the raw material may be, for example, a partial hydrogenation method in which the fluid is brought into contact with a hydrogenation catalyst to be converted into an olefin. In addition, there may be a case where the hydrocarbon-containing fluid is contained in the reactor after being recovered. In the case of a family compound, the total amount of the diaromatic compound in the total raw material supplied to the reactor is the total of the olefins having 4 or more carbon atoms contained in the total raw material supplied to the reactor. The amount is not more than 莫· 05 in terms of molar ratio. If the concentration of the aromatic compound in the raw material is too high, the reaction of the aromatic compound with the olefin having 4 or more carbon atoms in the reactor, and the aromatic compound and hydrazine At least one of an alcohol and a dimethyl ether The reaction becomes remarkable. It is not necessary to consume at least one of the olefin having a carbon number of 4 or more and the methanol and the dimethyl bond 312 ΧΡ / invention specification (supplement) / 97-01/96135332 30 200831453. When the aromatic compound is supplied to the reactor, the aromatic compound in the oral fluid is taken out of the system due to the catalyst formed by the reaction with the thinning of the upper sputum, and the aromatics in the fluid of the reactor are removed. The concentration of the compound is lowered. The ratio of the total amount of the aromatic compound-free compound to the total amount of the furnace having a carbon number of 4 or more can be obtained by separately supplying: = stream (4), by gas chromatography or the like. As a method of reducing the degree of aromatic compounding (four degrees) of the original money, a separation method by distillation may be mentioned. <Diluted gas> In the reactor, in addition to the olefin having 4 or more carbon atoms, In addition to methanol and dimethyl, in the middle, and less, there may also be a mixture of sarcophagi, aromatics, water vapor, carbon dioxide, carbon monoxide, nitrogen, argon, helium, and the like. Inert gas. Again, this In the gas release, paraffin and aromatics are slightly reacted depending on the reaction conditions, and are classified as a diluent gas because of a small amount of reaction. As such a diluent gas, impurities contained in the reaction raw material may be used as they are. The separately prepared diluent gas is mixed with the reaction raw material. Further, the diluent gas may be mixed with the reaction raw material before being placed in the reactor, or may be supplied to the reactor separately from the reaction raw material. As a preferred diluent gas, the carbon number is 4 The above stone sacrifice class. Better 312XP / invention manual (supplement) /97-01/96135332 31 200831453 At least one of the diced and diced. The inclusion of these sarcophagus materials, and because The material having a large heat capacity can be: the reaction temperature of the olefinic nicotinic acid, and it is easy to control the space velocity. The space velocity referred to herein refers to the reaction material per unit weight of the catalyst (the active component of the catalyst). The flow rate of the olefin having a carbon number of 4 or more, the catalyst weight means the weight of the catalytically active component which is used for the granulation and molding of the catalyst, and the yield and the adhesive. χ, the flow rate is the flow rate of the fine smoke (weight/time). The space velocity is preferably between 0.1Hr1 and 500ΗΓ1, more preferably between i 〇 jjf and 100 Hr-1. When the space velocity is too high, the conversion ratio of at least one of the olefin of the raw material and the hydrazine and the dimethyl ether is lowered, and a sufficient propylene selectivity cannot be obtained. Further, when the space velocity is too low, in order to obtain a constant throughput, the amount of catalyst required is increased, and the reactor is excessively large, and undesirable by-products such as aromatic compounds and paraffin are formed, and propylene is selected. ^ Reduced, so it is not good.

If the reaction temperature is too low, the reaction rate is low, and there is a tendency for more unreacted raw materials to remain, and the yield of propylene is also lowered. On the other hand, if the reaction temperature is too high, propylene is produced. The reaction rate is significantly lower. <Reaction pressure> 312XP/Invention manual (supplement)/97-01/96135332 32 200831453 1 The upper limit of the reaction pressure is usually 2 MPa (absolute pressure, the same applies hereinafter), preferably less than 1 MPa, more preferably 7. 7 MPa or less. The lower limit of the reaction pressure is not particularly limited, and is usually 1 kPa or more, preferably 5 Å or more. If the reaction pressure is too high, the formation of poor by-products such as stone _ and aromatic compounds. When the amount is increased, the yield of propylene tends to decrease. If the reaction pressure is too low, the reaction rate tends to be slow. <Resource consumption of the reaction> The molar flow rate of methanol relative to the methanol supplied to the reactor Ether The total of the flow rate is 2 times, and the total of the molar flow rate of methanol at the outlet of the reactor and the molar flow rate of the dimercapto ether is preferably less than 1%, more preferably less than 0·10/〇〇 in the reactor. The consumption of methanol and dimethyl (tetra) is small, and the amount of decyl alcohol and dimethyl ether at the outlet of the reactor increases, which makes it difficult to refine the olefin of the product. As the consumption of decyl alcohol and didecyl ether increases. The method 'is, for example, a method of raising the reaction temperature and lowering the space velocity. Further, in the present invention, the carbon number of the outlet of the reactor is 4 or more with respect to the molar flow rate of the olefin having 4 or more carbon atoms supplied to the reactor. The molar flow rate of the olefin is set to be 20% or more and less than 90%. The molar flow ratio is preferably 20% or more, less than 70%, more preferably 25% or more, and less than _. If the consumption of olefins having a slave number of 4 or more is too small, the amount of unreacted olefins will increase, and the flow rate of the fluid recovered to the reactor will become too large, which is not preferable. Conversely, if the amount of consumption is too large, paraffin will be produced by the side. As a poor compound such as an aromatic compound, the yield of propylene is lowered, which is not preferable. 12XP/Invention Manual (Supplement)/97-01/96135332 33 200831453 As a method of consuming the amount of olefin having 4 or more carbon atoms in the reactor, for example, a method of appropriately setting the reaction temperature and the space velocity can be mentioned. Here, the methanol, the dimethyl ether and the olefin having a carbon number of 4 or more are supplied to the reactor, and the composition of the fluid supplied to the reactor or the mixed fluid can be obtained by gas chromatography. When the flow rate of each fluid is measured by a general analysis method, the flow rate of the sterol and the dimethyl bond and the olefin having a carbon number of 4 or more at the outlet of the reactor can be determined by a general method such as gas chromatography or the like. The composition of the outlet fluid is quantified, and the flow rate of the reactor outlet stream f is measured or calculated. <Reaction product> As a reactor outlet gas (reactor effluent), a mixed gas containing propylene, an unreacted raw material, a by-product, and a diluent belonging to the reaction product can be obtained. The concentration of propylene in the mixed gas is usually from 5 to 95% by weight. The unreacted raw material is usually an olefin having 4 or more carbon atoms. Although the reaction conditions include at least one of decyl alcohol and didecyl ether, it is preferred to carry out the reaction under reaction conditions in which at least one of decyl alcohol and dimethyl ether is not left. Thereby, the reaction product and the unreacted raw material can be easily separated by the two U. Examples of the by-products include ethylene, a rare carbon having 4 or more carbon atoms, a paraffin wax, an aromatic compound, and water. [Separation step] * {Separation step in the first and second aspects}, "Separation of hydrocarbons and water having a carbon number of 3 or less: Step (2) > Reactor outlet gas system by cooling, compression, distillation, etc. The general separation step 'is a fluid (A) having a carbon number of 3 or less, a hydrocarbon having a carbon number of 4 to 312XP/invention specification (supplement)/97-01/96135332 34 200831453, And water-rich fluids.

As a second aspect of the separation step, the method comprising the following steps can be applied. After the water condensation is removed by the cooling and compression steps (4), the fluid separated by the steam residue into a hydrocarbon having a carbon number of 3 or less and the fluid having a carbon number of 4 or more (A)' will be rich in hydrocarbons having a carbon number of 3 or less. The fluid is separated by distillation into a fluid rich in hydrocarbons having a carbon number of 2 or less and a fluid having a hydrocarbon having a carbon number of 3. As a third aspect of the general separation step, a method comprising the steps of: cooling and After the condensation step removes the moisture condensation, the fluid rich in carbon number 2 or less and the carbon-rich number 3 are separated by distillation. a fluid and a fluid rich in carbon atoms of 3 or more, and a fluid rich in carbon atoms of 3 or more is separated into a fluid rich in carbon number 3 and a fluid rich in hydrocarbons having 4 or more carbons by distillation ( A) As a fourth aspect of the above-described general separation step, a method comprising the steps of: condensing and removing water by a cooling and compression step, and then distilling it into a hydrocarbon having a carbon number of 3 or less The fluid and the fluid (A) rich in carbon 4 or more smoke are separated from the fluid having a carbon number of 3 or less by distillation into a fluid having a carbon number of 2 or less and a hydrocarbon having 3 carbon atoms and rich in The fluid of the hydrocarbon having a carbon number of 3. In the first to fourth aspects of the above general separation step, if necessary, it is preferably 312XP/invention specification (supplement)/97-01/96135332 35 200831453 for quenching, washing, and In the case of dehydration, etc., in the case of oxygen-containing compounds: ^ in the reactor outlet gas, Qiu Qixi, everyone. Hunting by the bonfire step, will remove at least the ruthenium-containing compound of the knife. It depends on the reactor, carbon, etc. In the case of acid gas, _ is emulsified by p /, _ 3, and is divided into acid gases. The separation of the at least part of the water is mainly condensed by compression and cooling. It is preferred that the water removed by the adsorbent such as molecular sieve can be used to fly the activated sludge or the like to the process water. In the case of f-fat = 3 (sometimes referred to as "this process" in 1 time), it is known as the spoiler from the reaction, and ffl. ^ is recovered from the export rolling body. The water is preferably used as a helium gas source for the solution. In addition, it can also be used as a diluent gas. The reactor is received in the process, and the hydrocarbon having a carbon number of 2 or less from the reaction gas of the reaction H is more The high purity G::: obtained by steaming and other purification steps is used as the purity of ethylene. = is above. The purity of propylene is 95% or more, which is more than the above. More preferably 99.9% or more. The ethylene and propylene carbonate thus obtained can be used as a raw material of ethylene and (tetra) derivatives which are generally produced, for example, from the viewpoint of quality of impurities, etc., for example, it can be used for production by oxidation reaction. Ethylene bromide, B. ethanolamine, bis, etc., by chlorination to produce vinyl chloride mono-, 1 '1, dichloroethane, chlorinated ethylene resin, vinylidene chloride, or borrow Ethylene, low-density or high-density polyethylene is produced by polymerization of ethylene, and ethylbenzene is produced by ethylation of 312XP/invention specification (supplement)/97-01/96135332 36 200831453.

Here, "taken out from the process" means a reactor that is not recycled to the process, and may be directly supplied to other processes by the g, or may be temporarily stored in the tank via a pipe and then supplied to other processes. Further, it may be used as a fuel without being supplied to another process. As a first aspect of the method of recovering a hydrocarbon fluid (A) having a carbon number of 4 or more to the reactor, a method comprising the following steps may be applied; The carbon number of 4 or more, the flow, and the part (8) of (A) are taken out from the process, and the remaining fluid (6) is separated into a fluid having a lower aromatic product (% by weight) than the fluid (6) by a general separation method such as distillation. (D) a fluid with a carbon number of 4 that is lower in concentration than the flowing (6), and The fluid (D) is recovered to the reactor, and the fluid (Ε) is taken out from the process. U As a second aspect, a method comprising the steps of: discharging a hydrocarbon fluid having a carbon number of 4 or more by distillation or the like can be applied. The general separation method is to separate a fluid (F) having a lower concentration of aromatic compounds than a fluid (Α) and a fluid having a lower hydrocarbon concentration of carbon 4 (A) than at least a fluid (A), and at least one portion of the fluid (F). The process is taken out, and at least a part of the fluid (1) of the fluid (G) is taken to the working device, and the remaining fluid (H) is taken out from the process. The raw material containing paraffin having a carbon number of 4 or more is used. In the case of a dilute hydrocarbon raw material having a carbon number of 4 or more, the fluid (8) or the second state 312XP/invention specification (supplement)/97-01/96135332 42 200831453 in the above-described first aspect is difficult because it contains a large amount of stone. The bad composition flow Zhao, Cheng: Connection: 22 minutes, f line separation and refining. Therefore, the system is effectively used as a 'cracking nr' system to supply to the steam cracking process, whereby these fluids (8), (8) can become The raw material for the production of propylene in the steam cracking process. At this time, the colder at least - part of the disk is hydrogenated. The fluid with a higher paraffin concentration than the fluid (8) /-() is supplied to the steam cracking process towel by contacting the body (8) or the fluid (8) foot m/2. The fluid having a higher smoke concentration is supplied to the cracking process of the steam cracking process. Further, in the case of the solution, carbon deposition is likely to occur, which is not preferable. Further, in this case, the total concentration of the aromatics contained in the fluid (B) or the fluid (H) is preferably less than 5. When the volume %, more preferably less than 3 〇, and the volume of the aromatic compound is high, the amount of the aromatic compound is relatively high, and the ethylene yield tends to decrease, which is not preferable. The first aspect is also obtained.

[Production of propylene] Hereinafter, production examples and comparative examples of propylene using the above catalyst are shown. 1> 'The production of propylene was carried out using the above-mentioned catalyst. In the reaction, a normal-pressure fixed-bed flow reactor was used, and the above-mentioned catalyst 〇·1〇g, quartz sand was filled in a quartz reaction tube having an inner diameter of 6 mm. a mixture of this reactor, supplied by an evaporator It is prepared into isobutylene (40% by volume), decyl alcohol (20% by volume), benzene (〇·8 vol%) in the present invention as a simulated gas composed of the reactor inlet gas (the piping 104 of Fig. 1 or Fig. 2). a gas of butadiene (0.1% by volume) and isobutane (39.1% by volume). The reaction temperature (reactor inlet gas temperature) was set to 550. 反应 The reaction started 312XP/invention specification ( Supplement) /97-01/96135332 54 200831453 After 70 minutes, the product was analyzed by gas chromatography. The reaction conditions and reaction results at this time are shown in Table 1. The selectivity of propylene was 54.8%, belonging to Further, the reaction was further continued, and the time until the conversion of sterol was less than 99% was evaluated as the catalyst life. As a result, the catalyst life was 312 hours. <Example 2> In addition to the supply to the reaction The benzene concentration of the apparatus was set to 丨·6 vol%, and the isobutane and the alkane concentration were set to 38·3 vol%, and the same reaction as in Example 1 was carried out (the reaction was carried out by the method. After the reaction started for 7 minutes, the gas was used. Analysis of the product by phase chromatography. The reaction conditions at this time and The results are shown in Table 1. The selectivity of propylene was 54. 4%, which was a very high degree. Further, the reaction was continued, and the time until the conversion of sterol was less than 99% was evaluated as the catalyst life. The catalyst life was 305 hours. <Comparative Example 1 > The same as Example 1 except that the concentration of benzene supplied to the reactor was 3.2% by volume, and the concentration of Isobutyl I was 36.7 % by volume. The reaction was carried out in the same manner as in the above method. After the reaction was started for 70 minutes, the product was analyzed by gas chromatography. The reaction conditions and the reaction results at this time are shown in Table 1. The selectivity of propylene was 51. 4%, which was a very low level compared to Examples 1 and 2. This is because the raw material butene and/or decyl alcohol reacts with benzene to form a burnt benzene because the butene and/or methanol originally used for propylene generation is wasted wastefully. Further, the reaction was continued, and the time until the conversion of sterol was less than 99% was evaluated by the 312 XP/invention specification (supplement)/97-01/96135332 55 ZUU5J14^3 as the catalyst life. Compared with Examples 1 and 2, Moxibustion # σ ', the media life was 221 hours, and the benzene blocked the catalyst pores = the result. It is presumed that this is due to the burning of the tenth and the promotion of carbon deposition. ^In this way, according to the method of the present invention, by making the material group portion not recovered and taken out, the amount of the aromatic compound concentration of the reaction thief is low, and the monthly concentration of the reaction is low.
