摘要：

Catalysts derived from perovskite type oxides LaCo1-xMxO3 (M = Ru or Fe, x = 0.2) synthesized by a modified citrate sol-gel method were tested in the oxidative reforming of diesel for hydrogen production. Physicochemical characterization of the samples revealed differences in the surface area, crystalline size, reducibility and relative distribution of the cobalt active phase on the surface of catalyst. These properties have important implications in the catalytic behaviour of the samples in the oxidative reforming of diesel. The increase in reducibility and metal exposition implies higher reforming activity as it was observed for the catalyst derived from LaCo0.8Ru0.2O3.
