Abstract

Oxidative steam reforming of methane is one of the promising methods for the production of hydrogen or synthesis gas, which can be utilized for the synthesis of ammonia, methanol, dimethyl ether and fuel-range hydrocarbons. Performance of NiO-MgO solid solution with the promoting effect of noble metals such as Rh, Pt, and Pd on catalytic activity and carbon deposition were studied in oxidative steam reforming of methane under atmospheric and pressurized conditions. At low W/F condition such as 0.13 gh/mol, small amount of noble metals promoted Ni0.2Mg0.8O showed much higher catalytic activity than Ni0.2Mg0.8O catalyst that exhibited combustion activity due to the oxidation deactivation in oxidative steam reforming of methane under 1 atm. Reduction degree of Ni over noble metals catalysts was more effective to the high catalyst reducibility than that on NiO-MgO solid solution. Under pressurized conditions, large amount of carbon was formed on Ni0.2Mg0.8O; where as, the amount of deposited carbon was negligible on Rh catalyst. This is an abstract of a paper presented at the AIChE Spring Annual Meeting - The 5th World Congress on Particle Technology (Orlando, FL 4/23-27/2006).
