ABSTRACT:
A process for forming a supported metal carbide catalyst, for example, a Group VIB transition metal carbide, such as tungsten carbide, which process comprises the calcination of a carbon support that has been impregnated with a metal carbide precursor comprising a water soluble salt of: (1) a cation comprising nitrogen-hydrogen bonded moieties, such as a guanidine cation; and (2) an anion, such as a tungstate anion, comprising metal-oxygen bonded moieties, so that upon calcination the product formed is the metal carbide and the by-products comprise ammonia and carbon dioxide.
