NON-OXIDE METAL-CONTAINING CERAMIC CATALYSTS

摘要

Supported non-oxide metal carbide-containing catalysts are provided which comprise: (a) an oxide support, such as alumina or cordierite; (b) a passivating layer of a ceramic, such as silicon carbide; and (c) a non-oxide metal-containing ceramic catalytic component, such as a Group VI metal carbide or nitride, preferably tungsten carbide or molybdenum carbide.
