Abstract: A method for producing a metal nitride and/or a metal carbide, a metal nitride and/or metal carbide optionally produced according to the method, and the use of the metal nitride and/or carbide in catalysis optionally catalytic hydroprocessing. Optionally, the method comprises: i) contacting at least one metal oxide comprising at least one first metal M1 with a cyanometallate comprising at least one second metal M2 to form a reaction mixture; and, ii) subjecting the reaction mixture to a temperature of at least 300° C. for a reaction period. Optionally, the metal nitride and/or metal carbide is a metal nitride comprising tungsten nitride.

Abstract: Disclosed are novel catalyst compositions, catalyst precursors, processes for making catalyst precursors, processes for making catalyst compositions, and processes for converting syngas. The catalytic component in the catalyst composition can comprise a metal carbide and/or a metal nitride. This disclosure is particularly useful for converting syngas via the Fischer-Tropsch reactions to make olefins and/or alcohols.
