Description
Technical field
The present invention relates to a kind of preparation method of porous catalyst.
Background technology
Solid catalyst only has surface to play a role in catalytic fluid or gas reactant, therefore by solid catalyst system
It is most important into loose structure.Have in known technology and micropore is contained using activated carbon, molecular sieve, bentonite, float stone, diatomite etc.
The solid of structure is as catalyst carrier.Activated carbon and molecular sieve pores rate are high in these materials, but aperture is in nanoscale, hole
Footpath is too small and influences the mass transfer of reaction substrate and product, less efficient.The natural micropore material such as bentonite, float stone, diatomite
Porosity is low, equally exists the problem of mass-transfer efficiency is low.Other the above inert carrier occupies the substantial amounts of component of catalyst,
Also the efficiency of catalyst is significantly affected.
The content of the invention
The invention solves prepare the relatively low technical problem of catalyst efficiency using porous carrier, there is provided a kind of macropore catalysis
Agent preparation method.
Macroporous catalyst preparation method of the present invention, it is characterised in that including catalyst powder and combustible powder and adhesive are mixed
Close uniform, briquetting, cause in 450-650 DEG C of roasting, in 850-1000 DEG C of activation, the activation process equipped with steam and air
At least part combustible powder smoulder, macroporous catalyst is obtained after cooling.
The catalyst powder be at least one catalytic cpd powder, metal oxide powder, miberal powder, clay powder, additive powder,
At least one of mixture of anti-denaturant powder and these materials.
The combustible powder is at least one in the mixture of coal dust, coke powder, plant carbon dust, Plant Powder and these materials
Kind.
Described adhesive is at least one of mixture of coal tar, pitch, inorganic glue, organic gel and these materials.
The catalyst powder and combustible powder footpath are between 0.05-0.2 microns.
The catalyst powder is classified as 1: 0.5-1: 5 with combustible powder ratio.
Carbon content is between 0-55% in the macroporous catalyst.
Catalyst void prepared by macroporous catalyst preparation method of the present invention is the sky left after combustible powder is burnt
Gap, space aperture is between 0.05-0.2 microns, hence it is evident that more than activated carbon and molecular sieve bore diameter, these macropores can be obviously improved
The mass transport process of reaction substrate and product；Most of combustible is burned off simultaneously, can improve active ingredient in the catalyst
Ratio, thus improve catalytic efficiency；Manufacturing cost is low.
Embodiment
Macroporous catalyst preparation method of the present invention, it is characterised in that including catalyst powder and combustible powder and adhesive are mixed
Close uniform, briquetting, cause in 450-650 DEG C of roasting, in 850-1000 DEG C of activation, the activation process equipped with steam and air
At least part combustible powder smoulder, macroporous catalyst is obtained after cooling.
The catalyst powder be at least one catalytic cpd powder, metal oxide powder, miberal powder, clay powder, additive powder,
At least one of mixture of anti-denaturant powder and these materials.
The combustible powder is at least one in the mixture of coal dust, coke powder, plant carbon dust, Plant Powder and these materials
Kind.
Described adhesive is at least one of mixture of coal tar, pitch, inorganic glue, organic gel and these materials.
The catalyst powder and combustible powder footpath are between 0.05-0.2 microns.Due to the hole of macroporous catalyst be can
Combustion things powder is burned off what is left, therefore the aperture of the macroporous catalyst can be obtained by adjusting the particle diameter of combustible powder；
Multifarious macroporous catalyst aperture can be obtained by using the combustible powder of different pore size.
The catalyst powder is classified as 1: 0.5-1: 5 with combustible powder ratio.In the case where Microporous Carbon is not involved in catalytic reaction,
The catalyst powder is classified as 1: 0.5-1: 2 with combustible powder ratio, and now most of inert charcoal particle is burned out, catalyst
It is active more preferable；In the case where Microporous Carbon participates in catalytic reaction, the catalyst powder is classified as 1: 2-1: 5 with combustible powder ratio, institute
Member-retaining portion Microporous Carbon is stated in macroporous catalyst to obtain more preferable catalyst activity.
Carbon content is between 0-55% in the macroporous catalyst.In the case where Microporous Carbon is not involved in catalytic reaction, institute
Carbon content is stated in macroporous catalyst between 0-10%, now most of inert charcoal particle is burned out, and catalyst activity is more preferable；
In the case where Microporous Carbon participates in catalytic reaction, carbon content is more preferable to obtain between 20-55% in the macroporous catalyst
Catalyst activity.
Present invention is further illustrated below by way of separate embodiment.
Embodiment
