Description

1. Technical field

[0001] The preparation method of the high adsorption capacity zeolite molecular sieve adsorbent of the invention belongs to the technical field of preparation and modification of zeolite molecular sieves. Specifically, it relates to a preparation method of a modified 5A molecular sieve adsorbent with high carbon monoxide adsorption capacity. 2. Technical Background

[0002] With C 1 With the rapid development of chemistry, the application of carbon monoxide in the development of chemical industry is becoming more and more extensive. The synthesis of many chemical products such as formic acid, acetic acid, oxalic acid, dimethylamide, phosgene, polycarbonate, polyurethane and other compounds requires pure carbon monoxide; At the same time, in the synthesis of ammonia, toluene diisocyanate (TDI) and other industries, the existence of trace carbon monoxide in the gas will cause catalyst poisoning of some reactions, which must be removed; in addition, there ar...
