Abstract

The invention discloses a preparation method of a catalyst for removing a small amount of H2 from industrial CO gas. The catalyst is prepared by an impregnation method, nickel is taken as an active ingredient, transition metal is taken as an auxiliary agent, and active alumina is taken as a carrier. The catalyst prepared by the method has the advantages that: the preparation method is simple, the active ingredient is uniformly loaded, the obtained catalyst has high catalytic property, and CO and the H2 in the industrial CO gas can be subjected to methanation reaction, so that the content of the H2 in reaction tail gas is less than 400ppm, and the problem of purifying the CO gas in the carbonyl synthesis industry can be effectively solved.

Description

[0001] technical field [0002] The invention relates to a method for removing a small amount of H in industrial CO gas by using CO catalytic methanation reaction 2 The process technology and catalyst preparation method belong to the field of catalysts. Background technique [0003] Combining with our country's lack of oil, gas, and relatively rich coal resources, it is of great significance to develop chemical technology using coal as raw material. The preparation of a variety of bulk chemicals from CO separated from syngas, such as methanol, olefins, aromatics, formaldehyde, acetic anhydride, paraformaldehyde, dimethyl ether, ethylene glycol, and mixed alcohols, has become a research topic at home and abroad in recent years. One of the hotspots, among them, coal-to-ethylene glycol is an emerging technology in the field of coal chemical industry in recent years, which has significant economic and social benefits. The technology is based on the Fujian Institute of Materi...
