Title:
METHOD OF USING MOLYBDENUM CARBIDE CATALYST
Document Type and Number:
WIPO Patent Application WO2002076885
Kind Code:
A3
Abstract:
A molybdenum carbide compound is formed by reacting a molybdate with a mixture of hydrogen and carbon monoxide. By heating the molybdate powder from a temperature below 300 DEG C, to maximum temperature 850 DEG C, a controlled reaction can be conducted wherein molybdenum carbide is formed. A high surface area, nanograin, metastable molybdenum carbide can be formed when the reaction temperature is below 750 DEG C. The metastable molybdenum carbide is particularly suitable for use as a catalyst for the methane dry reforming reaction and the water gas shift reaction.
