• Methane reforming
• CO(2)
• Ruthenium
• Hydrogen production
• Alumina
• Ceria

The catalytic activities of ruthenium-based catalysts (5 wt% Ru) supported on alumina, ceria and ceria/alumina with different proportions of ceria (nCe10Al, n = 1, 3, 5; n = atomic ratio) were studied for the methane reforming reaction with CO(2) (CH(4)/CO(2) = 1) in the temperature range of 400-800 degrees C. Evaluation of coke deposited after the reaction showed carbon deposition on Ru catalysts supported on CeO(2), 1Ce10Al and 3Ce10Al, but not on Ru/Al(2)O(3) and Ru/5Ce10Al. Moreover, the sample Ru/5Ce10Al exhibited a higher activity than the other catalysts. To cite this article: M. Safariamin et al., C R. Chimie 12 (2009).
