Catalytic exchange performance of hydrogen-deuterium and methane on Ni-Rh/Al_2O_3 catalyst

The catalytic properties of the Ni-Rh/Al2O3 catalysts for the hydrogen-deuterium exchange of methane were tested with the fixed-bed micro-reactor.The results indicated that the conversion of methane increased by increasing reaction temperature when the temperature was less than 692K,the conversion of methane is not changed with increasing temperature when the temperature was higher than 692K under the same feed composition conditions.The conversion of methane was reduced with increasing the flow of reactants when the temperature was less than 692K,the conversion of methane did not change with increasing temperature when the temperature was higher than 692K under the same feed composition conditions.The conversion of methane was significantly reduced with increasing the flow rate of HD/CH4 when the flow rate was 1.1—2.5.
