CATALYSTS COMPRISING NIOBIA AND/OR TANTALA SUPPORTED ON TITANIA

摘要

CATALYSTS COMPRISING NIOBIA AND/OR TANTALA SUPPORTED ON TITANIA Catalysts comprising an oxide of a metal selected from the group consisting of (a) niobium, (b) mixtures of niobium and tantalum, or (c) tantalum supported on a titania support wherein at least a portion, and preferably at least about 25 wt.%, of said supported metal oxide is in a non-crystalline form. These catalysts have been found to be useful for synthesizing methanethiol and CH4 from mixtures of H2S and CO. Niobia on tantala is a useful catalyst for removing NOx from industrial waste gases.
