Abstract
The present invention relates to a deoxidizing catalyst for high concentration carbon monoxide synthetic gas, which comprises the compositions, in weight percentages, 5 to 10% of Cu, 2 to 5% of Mn, 0.2 to 2% of Co and 80 to 94% of activated carbon. The catalyst can deeply deoxidize high concentration carbon monoxide gas with the oxygen content smaller than 1%, and the content of residue oxygen in the purified gas is smaller than 1 ppm. The catalyst has the advantages of low cost, high catalytic activity for the reaction of CO and O2 to generate CO2, low reaction temperature and favorable catalytic activity.
Description
The invention belongs to a kind of synthetic gas deoxidizing catalyst, relate in particular to a kind of high concentration carbon monoxide synthetic gas deoxidizing catalyst.
At present, synthetic gas (CO, the H that reports both at home and abroad
