Coated catalyst containing metal oxides and catalytic decomposition process of ammonia and hydrogen cyanide in coke-oven gas

摘要

Metal oxide catalyst contains 2-5.5 wt.% nickel oxide and 0.5-3.5 wt.% cobalt oxide on a magnesium oxide support. An Independent claim is also included for a process for decomposing ammonia and hydrogen cyanide from coke oven gas before feeding into a Claus desulfurization plant by passing the coke oven gas over a catalyst containing 2-5.5 wt.% nickel oxide and 0.5-3.5 wt.% cobalt oxide on a magnesium oxide support.
