Abstract
A process for catalytic gasification of heavy oil of a specific gravity of higher than 0.7 with steam or steam/oxygen-containing gas characterized in that the heavy oil is contacted with chromium oxide catalyst or a catalyst comprising a mixture of chromium oxide and one or more of alkaline earth metal oxides, aluminum oxide, zirconium oxide, nickel oxide and cobalt oxide. More particularly, the present invention relates to a process for catalytic gasification of heavy oil of a specific gravity of higher than 0.7 characterized in that the heavy oil is contacted with a gasification catalyst comprising calcium aluminate, an alkali aluminate or tungsten-containing nickel and then the heavy oil is further contacted with said chromium oxide catalyst or chromium oxide-containing catalyst.
