ABSTRACT:
Silicon containing methanation catalysts e.g. those prepared by coprecipitation techniques, may be stabilized to prevent leaching of silicon species by a hydrothermal treatment comprising heating the reduced catalyst in a steam reducing gas atmosphere, lowering the temperature until liquid water species condense out, reheating to evaporate the condensed water and passivation in a mildly oxidizing atmosphere.
