Abstract

Abstract The present invention provides a method for producing raw materials for a reformer by cracking and desulfurizing petroleum fuels, characterized by cracking and desulfurizing petroleum fuels in a desulfurizer in the fuel cell electricity generation process at a temperature of 300 degrees-600 degrees C., preferably 350 degrees-500 degrees C., a pressure of 1-10 kg/cm2, an H2/oil of 500-2000, preferably 800-1000, and an SV of 0.5-4 hr-1 using a zeolite catalyst such as Y-type zeolite or a metallosilicate catalyst such as one having an Si/Me atomic ratio of 40-3200 where Me is Al, Ni, Co, Mo, W, Fe, Cr or Ga.
