Abstract

The present invention refers to processes for obtaining steam reforming catalysts containing nickel, cerium, lanthanum and copper oxides, free from potassium or alkali metals, preferably with the oxide layer being located externally with a thickness of less than 0.5 mm on the support particle, preferably the support being based on alumina, magnesium aluminate, hexaaluminates or mixtures thereof. The catalysts according to present invention show high activity, resistance to thermal deactivation and resistance to coke accumulation in the steam reforming reaction of hydrocarbons.
