説明
Abstract Fifteen amorphous Fe-Ni base alloys containing P and/or B as additives were studied to determine their catalytic activity for the hydrogenation of CO to produce mainly C1 to C3 hydrocarbons. The amorphous state is catalytically stable, if the reaction temperature is maintained considerably below the crystallization point of the amorphous alloy. With the exception of only one composition, the stable activity of the amorphous state is from several to several hundred times higher than the thermodynamically stable crystalline state of the same composition. Both the amorphous and the crystalline catalysts exhibit an activation energy of 100 ± 4 kJ/mol and a rate law −dP CO dt = kP H 2 1.0 P CO 0 . These results suggest that the active sites are of similar nature but different in number for the different structures and compositions of the catalysts.
