Steam reforming process and catalyst.

摘要

Hydrocarbon feedstocks including those containing sulfur are steam-reformed in the presence of a catalyst which in the unreduced condition contains nickel oxide, rare earth metal oxide, and zirconium oxide. The catalyst consists of 20-50% of nickel oxide, 10-25% of rare earth metal oxide and 25-70% of zirconium oxide. Preparation by treating an aqueous solution of nitrates or acetates of the metals with hydroxides or carbonates of ammonia or sodium to form precipitates, then drying, shaping and calcining.
