Abstract
The utility model relates to a hollow tooth ball-shaped catalyst carrier. The carrier is in a tooth-shaped hollow cylindrical particle shape, the middle part of the carrier is in a cylinder structure, the center of the cylinder is provided with an axial circular through hole, the diameter of the through hole is equal to the radius of the tooth-shaped hollow cylinder particle, the outer wall of the cylinder is provided with 3-10 axial arc-shaped opening grooves, the depth of the opening groove is 25% of the diameter of the tooth-shaped hollow cylindrical particle, the width of the opening of the opening groove is 70% of the radius of the axial through hole, and the length of the cylinder is equal to the diameter of the cross section of the tooth-shaped hollow cylindrical particle; and the catalyst carrier has good rollability, is uniformly mixed and filled with reactants, and has a larger surface area and larger voidage, and the phenomenon of tooth biting is not generated between the catalyst carrier and the reactant, so the flow resistance of the reactants in a catalyst bed is reduced, the possibility of coking is reduced, and the reaction efficiency and the utilization ratio of the catalyst are improved.
Description
Technical field
The utility model relates to a kind of hollow tooth spherical carrier of catalyst, particularly is shaped as the tooth sphere, and there is the catalyst carrier of open slot on the surface.
Background technology
The shape of current petrochemical industry catalyst for application carrier has sheet, annular, sphere and other irregularly shaped.These have difform catalyst carrier adsoption catalyst effectively.But, the different shape catalyst carrier of the prior art part that in course of reaction, all comes with some shortcomings, poor as sheet and ring catalyst carrier rollability, be difficult for reactant absorption evenly, easily cause catalytic reaction inconsistent.Ring catalyst carrier rollability is good, even mixed packing, but the bed space is little, and the resistance drop in the catalytic reaction process increases very fast, is unfavorable for giving full play to the due catalytic action of catalyst.Also have in the prior art at place, spherical carrier of catalyst axle center and offer axially extending bore, with the raising bed voidage, but reactant differs bigger to inner diffusion length everywhere from appearance, is unfavorable for improving the utilization rate of catalyst.
The utility model content
The purpose of this utility model provides the hollow tooth spherical carrier of catalyst that a kind of surface is provided with many axial circular arc open slots.
Hollow tooth spherical carrier of catalyst described in the utility model is shaped as profile of tooth open column shape particle, the centre is a cylindrical structure, the cylinder center is axial manhole, through-hole diameter equals the radius of profile of tooth open column shape particle, the cylinder outer wall is provided with 3～10 axial circular arc open slots, the opening groove depth is 25% of a profile of tooth open column shape particle diameter, and the open slot A/F is 70% of an axially extending bore radius, and cylinder length equals the diameter of profile of tooth open column shape particle cross section.
Catalyst carrier is mixed and made into by heat-resisting inorganic oxide material or inorganic oxide and molecular sieve.Inorganic oxide can be wherein two or more a mixture of aluminium oxide, magnesia, zirconia, iron oxide, titanium oxide, silica, amorphous aluminum silicide, natural clay or they; Molecular sieve can be mixture or the compound of any two kinds of mixtures or compound or three among micro porous molecular sieve, mesopore molecular sieve, large pore molecular sieve or the three.
The utility model compared with prior art has following good effect:
Hollow tooth spherical carrier of catalyst in pelletized form has good easy rollability, even with the reactant mixed packing, establish axially extending bore and outer wall within adding and be provided with many axial circular arc open slots, the surface area and the voidage of catalyst carrier have greatly been increased, the flow resistance of reactant in beds reduced, reduce the possibility of coking, improved the reaction efficiency and the utilization rate of catalyst.
The bulk density of catalyst carrier described in the utility model is littler by about 3% than the bulk density of the catalyst carrier that does not have circular hole.
