PURPOSE: To provide a method for reforming a heavy oil by which a light oil and hydrogen can be produced at a lower reactional temperature in a higher yield than those in a conventional method.
CONSTITUTION: This method for reforming a heavy oil comprises a steam reforming step for reforming a mixture prepared by adding steam to a heavy oil raw material consisting essentially of a hydrocarbon or a mixture obtained by adding steam and oxygen or air thereto in the presence of a catalyst prepared by adding one or more metals selected from Ni, Co and Mo or a metallic oxide thereof to a carrier comprising one or more oxides of alkaline earth metals selected from Ca, Mg and Ba and alumina under conditions of a reactional temperature within the range of 600-800°C, a reactional pressure within the range of 1-20kg/cm2 and a ratio of steam/carbon (mol/atomic ratio) within the range of 1-10. Thereby, hydrogen and a light oil can be obtained at the lower reactional temperature of steam reforming reaction in higher yield than those of a conventional method.
