Description
Technical field
The utility model relates to a kind of petrochemical industry used catalyst or guard catalyst; be applicable to, as light ends oil and the catalyst of heavy distillate or guard catalyst, be particularly useful for the catalyst as gasoline, kerosene, diesel oil, normal pressure wax oil, decompressed wax oil and residual oil or guard catalyst.
Background technology
Catalyst plays core important function at catalytic field, usual catalyst all has certain pattern, a kind of catalyst is in the industry along with application target is different, have different requirement to the aspect such as specific area, pore volume, intensity, pressure drop, mass transfer, fluid distrbution of catalyst, research shows that catalyst is made different exterior appearances and all can be affected the serviceability of catalyst in industrial aspect.
The exterior appearance of traditional catalyst has that cylindrical, Raschig ring shape, seven apertures in the human head are spherical, cloverleaf pattern, bunge bedstraw herb shape, wheel shape, gear shape, wherein cylindrical shape is a kind of conventional catalyst shape at petrochemical industry.
Chinese patent 201410396670.X discloses a kind of cylindrical ceramic honeycomb substrate, this carrier has pore passage structure along cylinder axis direction, one section of opening of carrier, and one end is closed, be not that carrier two ends have pore passage structure, there is no pore passage structure along surface, column axis direction simultaneously.
Chinese patent 200520074789.1 discloses a kind of cylindrical vector, carrier axis place is provided with and axially runs through hole, periphery is provided with many axial large semi-circular open slots, although this patent devises some macroscopical through hole or open slots on a catalyst support, but or can not effectively utilize the carrying out of catalyst support surface area maximum that duct is set, increase pore volume and the porosity of catalyst carrier, thus improve the appearance impurity ability of catalyst.
Above publication just protects the overall appearance structure of catalyst; Kaolinite Preparation of Catalyst cross section and surface be not at the catalyst of macroscopic perspective with pore passage structure; which limits catalyst and have high pore volume; for requiring in industry that high catalyst holds impurity ability; this kind of catalyst effectively can not meet instructions for use, and this catalyst surface and cross section are restricted in industrial application without the cylinder shape catalyst of duct or few pore passage structure.
