    摘要: A method for the treatment of a methanol reforming catalyst includes pre-aging the catalyst by baking it out in a dry atmosphere in order thereby to complete its inherent initial loss of volume before the start of the methanol reforming reaction. The method may be used for methanol reforming reactors in fuel-cell-operated motor vehicles.

    摘要: Mixed metal carbide catalysts that are active for catalyzing the net partial oxidation of methane to CO and H2 are disclosed, along with their method of making. The preferred catalysts of the invention comprise a mixture of at least two carbided metals that are prepared by the reaction of the metal oxides, alkoxides or nitrates with a hydrocarbon of the formula CnH2n+2 wherein n is an integer from 1 to 4. Optionally, the catalysts include an additional promoter and/or a catalyst support. Preferred catalysts are at least 50 wt % molybdenum, tungsten or chromium, and also contain a second metal selected from the group consisting of molybdenum, tungsten, vanadium, chromium, iron, niobium, tantalum, rhenium, cobalt, copper, tin and bismuth.
