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 CO2 (CH4/CO2 = 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 CeO2, 1Ce10Al and 3Ce10Al, but not on Ru/Al2O3 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). (C) 2009 Academie des sciences.
