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.

Abstract: Polyketones can be formed in enhanced yield by conducting the polymerization of the carbon monoxide and olefin monomers used to form the polyketone in a gas phase polymerization process in the presence of a catalyst support which is substantially saturated with an amount of a liquid, non-polymerizable diluent, for example, an organic diluent, which is effective in increasing the amount of polyketone formed over that which would be formed in the substantial absence of the diluent. Preferably, the catalyst is supported on a high surface area polyketone support (e.g., a carbon monoxide-ethylene high surface area support). Hydrogen gas can be used to reduce the molecular weight and increase the bulk density and thermal stability of the polyketone product.
