Catalyst porous ceramic carrier with high surface area

Abstract

The invention discloses a catalyst porous ceramic carrier with a high surface area, and belongs to the technical field of catalyst carriers. An outer arched porous carrier and an inner arched porous carrier are sintered into an arched structure, a first catalyst pouring layer and a second catalyst pouring layer are distributed in the outer arched porous carrier and the inner arched porous carrierin a staggered manner, slip casting is carried out by adopting a catalyst and adsorption gel, impurities in reactants are easy to capture, a contact reaction space is provided for the catalyst, the contact reaction area of the reactants and the catalyst is enlarged, on the premise that a reactant conduction gap is reserved, and the reactants can flow through the first catalyst pouring layer and the second catalyst pouring layer which are distributed inside and outside in the conduction process; and furthermore, a plurality of catalyst loading layers are arranged in the distribution diffusion carrier channel, the catalyst loading layers also realize catalytic reaction after impurities in reactants are adsorbed, and gaps are formed among the plurality of catalyst loading layers, so that thereactants are effectively prevented from being conducted and blocked.

Description

technical field [0001] The invention relates to the technical field of catalyst carriers, in particular to a catalyst porous ceramic carrier with a high surface area. Background technique [0002] The catalyst carrier supports the active components during the catalytic reaction and makes the catalyst have a specific physical form, but the carrier itself does not have catalytic activity. Traditional catalyst supports mainly include natural minerals, adsorbents, glass, polymers, etc., while porous ceramic catalyst supports have become a Catalyst support types that have received widespread attention in recent years [0003] The shapes of catalyst supports in the prior art include sheet, ring, sphere and other irregular shapes. These catalyst supports with different shapes can effectively adsorb catalysts. The uniformity and high distribution of the catalyst are extremely important to the adsorption effect of the reactants. In the prior art, the catalyst is only laid layer b...

AI Technical Summary

Problems solved by technology

In the prior art, the catalyst is only laid layer by layer on the catalyst carrier or filled in the catalyst carrier layer by layer. Although the surface area increases, the distribution of the catalyst is too tight, which often has a certain impact on the flow of the reactants; In addition, the catalyst carrier in the prior art still needs to improve the capture and adsorption of reactants.
