Abstract

A high-activity deoxidant for the deep deoxidization of N2, H2, CO, CH4, C2H4, C3H6, etc is composed of active component (the low-valence oxide of Mn and Fe) and the carrier chosen from cement, gypsum, kaolinite, alumina, diatomite, etc. Its preparing process is also disclosed.

Description

technical field [0001] The present invention relates to a high activity deoxidizer and its preparation method, more specifically, the present invention relates to a kind of double metal oxide as the active component, which is especially suitable as a high activity deoxidizer for removing oxygen from gaseous or liquid materials. agent and its preparation method. Background technique [0002] As early as 1925, British Mande and others prepared a deoxidizer composed of iron powder, iron sulfate and hygroscopic substances in order to prevent the transformer from igniting and exploding. In the 1960s, there were reports of synthesis gas deoxygenation catalysts abroad. The active component of these catalysts is MoS 2 -CoS, Cu, Pb, Pt, Pa, and the carrier is mostly Al 2 o 3 , activated carbon, silica gel, molecular sieve and diatomaceous earth, etc. Among these catalysts, noble metals mainly composed of Pt and Pa have high catalytic deoxidation activity, but such catalysts are ...
