Abstract

The invention provides a deodorization adsorption material and a preparation method thereof. Asphalt base special activated carbon is mainly adopted as a carrier framework material, activated components such as copper and potassium are carried on the carrier framework material, the adsorption material is prepared through procedures such as dipping and calcining, and effective protection on substances such as ammonia gases, hydrogen sulfide, methyl mercaptan and methylamine is achieved.

Description

technical field [0001] The invention belongs to the technical field of impregnated carbon, and comprises an adsorption material with excellent protective performance and a preparation method thereof. Background technique [0002] At present, domestic general deodorization adsorption materials are mainly prepared with coal-based activated carbon as the carrier, but this kind of adsorption material prepared with coal as raw material not only has a short protection time, but also has high ash content, uneven packing density, and high packing density. , causing the filling tank or filter to be heavy and bulky, especially in the case of limited space, the disadvantages are more obvious. [0003] Compared with traditional activated carbon, pitch-based spherical activated carbon has a series of advantages such as good sphericity, uniform packing density, large specific surface area, high strength, wear resistance and corrosion resistance. In particular, the adsorption material pre...
