The present invention relates to a method and apparatus for uniformly loading particulate matter into a cylindrical bed or vessel. More specifically, the catalyst directivity for loading the catalytic reaction bed is because a plurality of concentric circles of catalyst particles on the entire circular surface of the catalyst bed simultaneously distribute catalyst particles or the like on a large diameter cylindrical vessel while simultaneously flowing the catalyst in a rounded line. It relates to packaging orientated packing (COP). The present invention relates primarily to ensuring that a catalyst, such as a cylindrical compression catalyst with stability of elevation extrusion, is uniformly filled in the bed at a high rate relative to volume.

It is a special object of the present invention to increase the packing density of particles which contain spherical particles and have a stability against high angle extrusion, and therefore simultaneously by means of a number of concentric round lines the bed traverses the entire diameter of the vessel. It is supposed to be done. A composite wheel of particles, such as a catalyst, is made up of a single rotary disk or a uniform rotation of the rotor that divides the catalyst flowing from the head outlet pipe into a number of radial fragments, the fragments having different diameters. As a result, the exit velocity of the catalyst particles from each segment of the disk distribution plane or from the sector gear creates a number of different radial throwing distances in the bed or vessel. Since all the fragments of the disk are rotated at the same speed, the concentric round lines of the catalyst create a line in the vessel, which allows them to be positioned simultaneously with adjacent annular wheels.

Such annular rounds are preferably relatively narrow in radial width but preferably a distance progressively different radially from the axis of the vessel to form a plurality of concentric round lines to uniformly cover the catalyst bed.

Catalytic reaction vessels having one or more fixed catalyst beds are now usually filled using catalyst distributors. This technique is known as catalyst directional packaging (often called COP loading) and is particularly useful for making the permeability and overall density of the catalyst bed uniform. In conventional catalytic processes, catalyst particles are generally produced by extrusion into cylindrical rods of 1 / 16'-1 / 4 '' diameter. Such extrudates are typically made of alumina, silica-alumina or synthetic or natural zeolitic materials and are generally less expensive to produce than spherical catalysts. However, such extrusion occupancy has the stability of the high angle extrusion: that is, the angle at which the pile of freely standing material is stabilized. Therefore, these are difficult to distribute evenly on a large diameter cylindrical container. Moreover, due to this difference in particle size, of course, during manufacture and loading, they break and break in the process reactor, and if the bed is filled by sole gravity from the central point in the vessel, they tend to be "classified" or separated.

The primary purpose of COP loading is to minimize voids and subsequently to local "hot spots" that may occur during the exothermic reaction of hydrocarbons with catalyst particles. In addition, the outflow distribution of the reactants in the reactor is improved by increasing the packing density of the solid particle material and the catalyst particles. Moreover, the increase in bed density limits the stability of the bed when the reactor starts outflow and is hydraulically driven by fluid outflow through the reactor.

In general, the amount of catalyst can be increased by several percent in existing vessels. In contrast, several percent less reactor volume requires the same amount of catalyst in the new vessel.

Generally, the above-described catalytic directional loading apparatus includes a distributor plate (disc) having a uniform diameter and a plurality of radial knives or pin parts at the apex of the rotating disc. In general, the distributor is either a conical assembly or one of the flat circular plates. However, the speed of the distributor may vary in order to distribute the catalyst across the entire cross sectional area of the bed, since the distance the catalyst is thrown is proportional to the disk speed. When the disk is a flat plate with wings formed there, a few holes are formed in the plate, causing some catalyst particles to drop the rotating part directly toward the center of the reaction vessel downwards.

US Patent No. 3,804,273 Uh1 relates to an apparatus for loading a catalyst bed with a radial distributor with a single conical surface. The only way to distribute the catalyst across the complete bed diameter is to increase and decrease the speed of the rotating disk.

U.S. Patent No. 3,972,686 introduces a small amount of catalyst falling through a plurality of grooves or holes near the center of the bed and the winged plate and the remaining catalyst falling to the side of the vessel. The system also needs to vary the speed of the rotating plate to load the catalyst to cover the entire level of the catalytic reaction bed.

A particular disadvantage of such conventional devices is the fact that they fall into circular or annular hills which tend to separate catalyst particles falling there at one speed of the catalyst. Larger particles roll down to the ground or outside the hill when smaller particles stop on their own hills. To some extent, these difficulties can be mitigated by changing the speed of the rotating disk, but significantly slowing the disk speed increases the loading time of the reactor bed, since the loading rate is proportional to that speed.

On the other hand, the excess speed of the disc results in blowing the catalyst out of the plate without having to wait long enough to control the radial throw distance. Moreover, the interior of such a bed is usually too dusty for the operator to actually see the bed with the catalyst in the loader, making it difficult to control the speed of the plate to achieve the desired radial throwing distance. Therefore, it is necessary to determine the possible level of distribution by the catalyst of the numerous drums loaded at a given bed level. Such a process is a waste of time and is not necessarily accurate and sufficient to ensure bed filling levels.

In practice, it is common practice to fill the bed with an outer edge, for example, higher than 6-12 inches as needed and then alternatively increase the height of the center level. The height of the central level is to increase the height throughout the reactor on the reactor, such as the depth of the bed or beds, at the outer edges, etc., by a similar amount. This problem is more severe when the container contains several separate beds, each of which is supported by a separate support "screen" and the beds below it must be filled through the opening in the center of the bed support where the beds are elevated. Become. Therefore, visual observation becomes more difficult.

Loutaty et al., US Pat. No. 4,306,829, introduce a catalyst particle distributor in the reactor or a grain distributor in silos. The distributor includes a flexible hand strap supported by the ribs along the length of the drive shaft. The grips are preferably made of reinforced rubber and are of equal length or progressively longer and longer apart from the feed hopper effluent. As examples, a system that is satisfactory for filling a model of a reaction vessel with a diameter of 60 cm (about 2 ft) is indicated. It is evident that the active length of the rotating hand strap changes its diameter by the speed of the working shaft and changes its interaction by the fall of catalyst particles. Effective loading of the vessel with each of the above mentioned devices is limited to a reactor of relatively small diameter, for the reasons mentioned above.

Farn ham, U. S. Patent 4,433, 707, assigned to the assignee of the present invention, evenly distributes catalyst particles from the center of the vessel to the outer wall using multiple plates of different diameters rotated at the same speed by a single operating axis. By introducing a method and apparatus for uniformly filling the reaction vessel at each level. Preferably, it is used as the largest diameter closest to the raw material feed hopper tube of the three conical disks. The upper disk includes a central inlet that allows the catalyst to be supplied to each of the lower disks. Since the disks are of different diameters, each one spreads the catalyst into different zones around the vessel by means of an actuating shaft rotating at constant speed. The system is very pleased to deliver the catalyst to smaller diameter vessels and deep beds. A suitable "tofu" room is preferably used on top of the container or on top of each of several beds. However, this method is also limited only to making a few annular round lines at the same time without changing the rotational axles.

Federal Republic of Germany Patent No. 2,703,329, patented in 1978, introduces another particle loading system using a plurality of disks that form a space in the axial direction that is rotated by a common operating axis. The form of operation is similar to the farm ham patent mentioned above.

According to the present invention, there is provided a catalyst particle loading method for providing an essentially uniform packing density to each of a plurality of adjacent annular areas across a shear area of a catalyst bed in a large diameter reaction vessel.

The present invention is directed to rotating the disc-shaped member such that the catalyst feed flow is essentially at constant velocity flow on the surface of the disc-shaped member to rotate about an axis generally perpendicular to the vessel described above.

On the surface of the disc-shaped member, the conveying flow is divided into a plurality of or radially extending sectors having a vertex essentially common to the axis of rotation of the disc-shaped member, each of which is a container as described above. Have a square angle with the other sectors in proportion to the horizontal plane of one of the plurality of associated annular areas on the bed surface of the catalyst, the radius of each sector being proportional to the radius of the associated annular area,

By rotating the disk-like member at an essentially constant speed, catalyst particles are distributed radially without essentially overlapping the non-adjacent annular area from the angular sector to its associated annular area, the annular area being reaction vessel. The catalyst particle loading method is characterized in that adjacent to each other across the cross-sectional area of the reaction vessel to provide a uniform catalyst distribution across the surface of the catalyst bed within.

According to another aspect of the present invention, in a method for loading catalyst particles in a substantially uniform high density across a bed in a large diameter vessel, the present invention provides an essentially cylindrical shape with an annular column concentric with the cylindrical column described above. Distribution by dropping catalyst particles by gravity in the inner column,

Deflecting said annular column on a single disc shaped member rotating about an axis concentric with said cylindrical column,

On the disc-shaped member, the annular column is divided into a plurality of radially extending sectors having a vertex essentially common to the axis of rotation of the disc-shaped member,

Each of these sectors starts at the same radius outward from the apex and is proportional to the radius of the annular area associated with the angle of inclination with one of the other sectors in the vessel that is proportional to the horizontal area of the associated annular area of the surface of the catalyst bed. Has a radius of

The cylindrical inner column is divided into a plurality of separation flow passages rotatable to the disc-shaped member and essentially radially perpendicular to the column, each separation flow passage having a different radius but shorter than the radius of any sector,

By rotating the disk-like member, catalyst particles are radially distributed from each of the sectors and flow into the associated annular area, each annular area being concentrically adjacent and essentially uniformly thick across the cross-sectional area in the vessel. And a catalyst bed having a mean density and forming a catalyst bed.

According to another aspect of the present invention, in the catalytic loading device for uniformly distributing a large diameter bed in the radially transverse direction in the reaction vessel,

The present invention includes a hopper means for supplying catalyst particles in a feed pipe means having a discharge port extending generally in a central direction in the reaction vessel,

A disk-shaped member for providing a distribution surface under the outlet of said supply pipe means, said distribution surface on said disk-shaped member being divided into a plurality of radially extending sectors having a common vertex at the center of the disk-shaped member; The sectors start radially outward from the apex at the same distance and each sector has an angle with another sector proportional to the horizontal plane of the associated annular area on the surface of the catalyst bed in the vessel, the radius of each sector being And a driving means which is proportional to the radius of the associated annular area and which causes the disk-like member to be driven about its center.

According to another aspect of the present invention, there is provided a feed pipe which includes a hopper for uniformly distributing the catalyst particles radially onto a large diameter bed in the reaction vessel, and which can be supported by the reaction vessel for feeding the catalyst into the reaction vessel. In the catalyst particle loading apparatus comprising a means, and a drive means for rotating the earthquake catalyst distribution means about its center for rotation in the reaction vessel under the supply pipe means, the present invention is common to the center of the disk-shaped member A distributing means having a dispensing surface distributed into a plurality of radially extending sectors having vertices, the respective sectors starting at a constant distance radially from the common vertex outer axis, wherein the common vertices Other sectors in which each sector is proportional to the horizontal plane of the associated annular area on the surface of the catalyst bed in the vessel. Located where it may have an angle between and, the radius of each of the sectors is proportional to the radius of the associated annular area, concentrically annular of the catalyst which rotates the disk-like member at essentially constant speed and simultaneously crosses the surface of the catalyst bed. A catalyst particle loading apparatus comprising means for reducing the volume.

In practicing the method of the invention, a catalyst distributor, which is a single sequential or disc shaped member, is placed at an appropriate level on the bed to be filled. The catalyst is then fed to the distributor from a hopper with a feed tube positioned essentially so that the cylindrical catalyst column falls on a single rotor or disk part.

The catalyst particles are then distributed by a single disk across the entire diameter of the bed at essentially uniform density, while forming a plurality of annular catalyst round lines co-centered with the vessel or bed center. Such operation is achieved without changing the speed of the disc by directing the cylindrical catalyst column into a number of arched linear gears or different radial length portions on a single rotating disc. Preferably, each arched portion has a volume proportional to one of the annular areas of the bed of the cross sectional area of the container. The required volume is formed by the inclusion of an angle on the disk and the radial length of the arched linear cog wheels. In the preferred form of the disc, it is desirable to have different volumes such that each adjacent arched linear gear or portion forms such an annular catalytic round in a bed of essentially the same width.

By the total cross sectional area of the vessel, the cylindrical catalyst volume exiting the feed can be divided into an outer annular column and an inner cylindrical column. In a preferred specific example, this method can be achieved by a frusto-conical component extending upwards and inwards into the feed tube from the main distribution surface of the disc. The critical substrate and main plate of the conical part generally form an auxiliary hopper or storage volume that supplies catalyst to another, many separate, arched outlet passages of different radial lengths perpendicular to the column. Each of these other outflow passages is also rotated by a single rotor or disk-like member. Preferably, each of these outlet passages is shorter than the radius of any arched portion or sector formed by the disk.

By rotating the plate uniformly, each of the plurality of arched outflow passages forms an annular round line of concentric circles of different diameters. These wheels simultaneously cover the surface area of the catalyst bed support in the vessel containing the catalyst.

Since each wheel (rounded line) is formed simultaneously at all levels, the depth of the catalyst is uniform across the entire vessel or bed diameter and the resulting catalyst bed has a high average density compared to the same vessel or bed volume.

In order to better understand the present invention, the effects of the present invention will be described with reference to the accompanying drawings through preferred embodiments of the present invention.

FIG. 1 is a diagram illustrating the application of the method of the present invention to the directional catalyst loading of a large diameter catalytic reaction vessel 10 using a catalyst loading apparatus 12 of the preferred type so that the catalyst particles lie in a concentric round line. will be. As shown in FIG. 2, a plurality of concentric rounded or radial lengths of such annular widths may be used to fill the bed 16 with catalyst at the same depth and density across the diameter. Cover the entire diameter at the same time. This method covers the entire diameter at the same time, especially after precipitation. This method relates, in particular, to catalyst loading with a high angle of stability, such as cylindrical extruded particles of the catalyst which are relatively stationary after precipitation.

As shown in particular in FIG. 1, the vessel 10 includes a plurality of beds 16, each of which is formed on a catalyst support or screen 18. As shown in the figure, multiple support structures 18 may be provided such that each of several successively interconnected outlet beds 16 is arranged on one over the other. In order to ensure that each bed 16 is filled with a uniform density throughout its height or depth, the axial length of the catalyst distribution device is relatively short such that it is underneath the top of the bed or the upper support 18, or a vessel ( It is also important to be able to fill the top of 10) as sufficiently as possible, with little or no head room on top of the catalyst bed 16. For this reason, the installed catalyst distribution sequential part 20 according to the invention is divided into a plurality of arched pieces or linear gears 24 having a common vertex at the axis of rotation 30 of the disc part 22. Primary distribution surfaces formed by 22). However, as shown in the figures, each piece or linear gear has a different radius from two of its adjacent linear gears, and two desirable pieces of the same area are diameters of each other in order to balance the sequential dynamics. In opposite directions.

In the particular example shown in FIGS. 3 and 4, the radial rib component 26 forms a linear gear 24 and has different radial lengths as shown in the figure. The rib part 26 extends axially away from the dispensing surface of the plate 22 and generally extends perpendicular to the dispensing surface of the plate 22. In addition, each linear gear or piece 24 has a different angle of incidence and the total volume of catalyst that angle, along with the depth of the ribs 26, may fall on each rounded line on the surface of the bed 16. It was also particularly noteworthy to decide. It is of course also understood that the total volume of each linear gear or fragment is proportional to the area of the rounded line 14 of the corresponding catalyst that will form on top of the bed 16. In general, the volume of such linear gears 24 is also proportional to the width of each rounded line proportional to the circumferential area of the rounded line and adjacent rounded lines formed by the linear wheels or fragments 24.

As specially shown in FIG. 4, the catalyst is fed by a feed tube 28 having a shaft 30 to a distribution surface formed of a plate 22 and a respective piece 24, which shaft 30 The distributor plate 22 generally has a coaxial shaft with an actuating shaft 32 attached, such as by a wheel barrel 34 and a key or actuating pin 36.

As shown in FIG. 1, the distribution system of the present invention may be used in conjunction with conventional catalytic aromatic packaging equipment. As can be seen there, the hopper 38 is loaded as a catalyst and feeds the catalyst through the feed pipe 40 to the low feed hopper 42 by gravity. The hopper 42 holds the head of the catalyst fixed on the dispensing disk 20, preferably over the passage 44 formed in the upper grating 18, such as by the arm 49 lying on the axis, or It is preferably supported at the upper flange 46 of the vessel 10. The rotary disc 20 can then be operated with the actuating shaft 32 and the shaft 20 at the required speed, either by local air or by an electric motor 48 mounted on the low hopper 42. The operation of the motor 48 may be via an air hose or wire 50. Alternatively, the shaft 32 can be rotated by extending the working shaft 32 on the flange 46 to an external motor (not shown).

A particular problem with the distribution of catalysts in large diameter vessels is the uniform catalyst distribution near the center of the vessel. It is very important to ensure that the catalyst is placed evenly across the center, including, for example, 8-15 feet of appetizer vessel diameter. It is not satisfactory at all to drop the catalyst through the middle of the distribution plate and drop it out from the center heap. According to a preferred specific example of the present invention, this problem is solved using a plurality of rectangular tubes or channels 52, 54, 56 and 58, each having a different radial length. As best shown in FIG. 5, these channels produce additional annular catalytic distribution rounds with the plate 60 supported on the bottom collar 62. The plate 60 is provided with a lower collar 62 by a nut 66 and a plurality of grooved nails 64 which allow the pin 60 to maintain adequate space in proportion to the flange 68 of the column 62. I support it. The plate 60 itself acts as another catalyst distributor through the operation of the radial rod 70 carried to its apex surface. A suitable doorway 72 that forms a space radially from the axis of rotation of the plate 60 controls the amount of catalyst intended to flow out of the deepest rounded line.

Although not shown in detail, the feed pipe 28 adjusts the amount of catalyst flowing annularly into the composite linear gear 24 at an appropriate ratio as compared to the amount of catalyst flowing out cylindrically over the upper and inner edges 87 of the disk 86. To the conical surface of the frusto-conical disc 86 by supporting the cutting cone disk 81 with a setscooter 31 and adjusting the sliding collar 29 up and down. It can also be seen that it is positioned proportionally adjustable, in which the chamber 88 formed of the cut-cone section 86 and the plate 22 is connected to the tubes 52, 54, 56 and 58 and the plate. And distributes the catalyst to 60. Similarly, the outlet between plate 60 and collar 68, as mentioned above, is supported by rod 70, through orifice 72 The entire catalyst flow is regulated from the edge of the plate 60.

As best seen in FIG. 5, the supply of catalyst exiting feed tube 28 into the inner cylindrical portion is fed through four rectangular tubes 52, 54 through forward outlet 84 in plate 22. Outflow to (56) and (58), wherein the catalyst passing through the distribution plate 60 passes through the four circular outlet 90 formed in the plate (22).

Each forms tubes 52, 54, 56 and 58 of different radial lengths shorter than any radial passage of linear gear 24, so that the catalyst feeds into the outer portion of the bed or vessel. When falling off at 24, round or annular portions of the inner diameter of the catalyst bed are simultaneously filled. At the same time, the catalyst passing through the outlet 90 is the deepest part of the bed, depending on the spacing of the plates 60 in the collar 68 and the radial arrangement of the rods 70 and the adjustment of the size of the orifice 72. It is optionally placed on. In a specific example of the invention, a single stem is placed by ten arched pieces 24 and four by tubes 52, 54, 56 and 58 and two plates 60. It is therefore also seen that it enables the distribution of the catalyst over a number of bands forming 16 separate rounded lines in the example of the present invention, which consist of lying by).

In this apparatus, the collar 62 and the plate 60 are connected to the distribution plate 22 so that disassembly is possible by the screw 80. The pipes 52, 54, 56, and 58 are formed as permanent parts of the plate 22. Alternatively, the complete sequential parts may be made as a bundle or other part permanently connected, or as disassembleable connection to the distribution plate 22. It will be apparent to one of ordinary skill in the art that plate 22 may be better conical than flat if necessary.

Each of which comprises a single catalyst distribution disk or a rotor or multiple outlet passages lies in a concentric annular round line of limited concentricity but is approximately the same radial width and lies across the entire circumference of the vessel 10. The chair is preferably rotated at constant speed. Since the speed is defined as such a constant and determined by the bed diameter, at the same time the rotor essentially forms the catalyst on the entire cross section of the vessel. Once adjusted, the speed remains largely constant while each bed is completely filled from the support 18 to the top of the bed 16. Placing such a bed evenly throughout its depth results in an increase in density of the total catalyst volume that can be loaded throughout the vessel or into each bed. In actual practice, it has been found that there is an increase in density of about 10% as measured by the weight of the total catalyst that can be loaded into the volume of a known container using the varying speed of the rotatable disk compared to the conventional COP loading method. . Since the rate of conversion of the hydrocarbon feed through the vessel is dependent on the total volume of the catalyst, the present invention provides a higher feed rate of hydrocarbons through the reactor for yield of the same product at a constant feed rate in the same volume of vessel, Makes it possible to increase. Both of these conditions are highly desirable in a hydrocarbon feed process for contact conversion, and have been shown to significantly reduce costs in such a process.

The above specific examples of the present invention will be particularly concerned with loading extrusion catalyst particles across the complete cross section of a large diameter reaction vessel. However, the method and apparatus may also be adapted for loading spherical or other special materials such as pellet catalysts or grains, such as in silos. Other contact materials in the form of particles, such as sulfuric acid absorbents, and ion exchange materials are also often hostile to large diameter containers. The present invention is particularly useful for maintaining high density throughout the bed of solid particles in large diameter vessels in which their function is large.

From the foregoing description, various modifications and replacements are possible for those skilled in the art, in the device or in the method of adjusting such a device, all such modifications or replacements being made with the appended claims. It should be seen as belonging to and included in the category of scope.
