摘要：A process of enhancing both the activity and the methane selectivity of aDispersed Active Metal (“DAM”) hydrogenation catalyst is disclosed wherein the DAMundergoes low temperature oxidation in a slurry phase to form a stable, unique oxidizedcatalyst precursor that is subsequently reduced to form an enhanced catalyst bytreatment with hydrogen-containing gas at elevated temperature, wherein reduciblepromoter metals comprising one or more of rhenium, ruthenium, palladium, iron andcobalt are added to the DAM. The promoter metals are mixed with the oxidized catalystprecursor as a solution of their reducible salts. The oxidized catalyst precursors are againrecovered from the mixture and treated with hydrogen-containing gas to simultaneouslyform the metals and reactivate the DAM catalyst.
