THE REACTION OF CO2 WITH CH4 TO SYNTHESIZE H-2 AND CO OVER NICKEL-LOADED Y-ZEOLITES

Nickel metal introduced into Y-zeolite exhibited a high catalytic activity in the dehydrogenation of methane and in the hydrogenation of carbon dioxide with methane to obtain hydrogen and CO at about 850 K. The activity strongly depended on the nickel amount in NaY, and the catalytic properties were influenced by the kind of cations in the Y-zeolite. The higher CO2 conversion was obtained over Ni supported on non-acidic zeolites.
