摘要：
The reforming reaction between CH4 and CO2 over Ni/Al2O3 at 700 degrees C has been found to show a deuterium kinetic isotope effect and a pattern of kinetic orders which depends on the reactant ratio. It appears that methane activation is rate limiting when CO2 is in excess but that removal of carbonaceous matter may become rate determining when there is excess CH4. With Rh/Al2O3 the adsorption of methane is partially reversible, the kinetic isotope effect has an intermediate value and removal of deposited matter is rapid.
