A kind of catalyst preparation method

Abstract

The invention relates to a catalyst preparation method, which uses a catalyst preparation device, the catalyst preparation device includes a support plate, a turning mechanism, a clamping mechanism and a spraying mechanism, and a turning mechanism is installed in the middle of the end surface of the support plate, A clamping mechanism is installed on the overturning mechanism, a spraying mechanism is installed on the support plate, and the spraying mechanism is located above the clamping mechanism. The invention can solve the problem that when the catalytic liquid is sprayed onto the catalyst carrier, the catalytic liquid cannot be evenly sprayed onto the catalyst carrier, resulting in the catalyst carrier not being able to absorb the catalytic liquid uniformly, affecting the catalytic effect of the catalyst carrier during use, and affecting the catalytic reaction rate It can also solve the problem that the existing device cannot turn the catalyst carrier intermittently at 180 degrees during spraying, resulting in competitive adsorption, affecting the absorption efficiency of the catalyst carrier to the catalytic liquid, and the catalytic liquid cannot be recycled, which is easy to cause the catalytic liquid Wasted conundrum.

Description

technical field [0001] The invention relates to the technical field of chemical catalysts, in particular to a catalyst preparation method. Background technique [0002] Catalyst, English name catalyst, is a substance that changes the reaction rate but does not change the total standard Gibbs free energy of the reaction. It is generally defined as a substance that can change the chemical reaction rate (increase or decrease) of the reactant in a chemical reaction without changing the chemical balance. , and its quality and chemical properties have not changed before and after the chemical reaction is called a catalyst (a solid catalyst is also called a catalyst). There are many methods for the preparation of catalysts. The traditional methods include mechanical mixing, precipitation, impregnation, solution evaporation to dryness, hot melting, soaking (leaching), ion exchange, etc., which have been developed in the past ten years. New methods include chemical bonding and fibro...

Problems solved by technology

[0005] The present invention can solve the problem that the existing catalyst preparation device cannot evenly spray the catalytic liquid onto the catalyst carrier when spraying the catalytic liquid onto the catalyst carrier, resulting in the catalyst carrier being unable to absorb the catalytic liquid evenly and affecting the catalyst carrier when used. The catalytic effect affects the catalytic reaction rate. It can also solve the problem that the existing catalyst preparation device cannot turn the catalyst carrier intermittently at 180 degrees when spraying, which may easily lead to competitive adsorption when the catalytic liquid is sprayed onto the carrier. It affects the absorption efficiency of the catalyst carrier to the catalytic liquid, and the catalytic liquid cannot be recycled, which is easy to cause the waste of the catalytic liquid
