PURPOSE:To permit continuous steam reforming using Ru catalyst for a long time by treating raw hydrocarbon previously by hydro-desulfurization and allowing the hydrocarbon to contact with Ru catalyst while maintaining the S-content at below a specified value. CONSTITUTION:In a process for reforming raw hydrocarbon with steam using Ru catalyst, the raw hydrocarbon is previously hydro-desulfurized, then allowed to contact with Ru catalyst while maintaining the S-content at below 0.05ppm by wt. Said Ru catalyst includes all kinds of steam reforming catalyst contg. 0.5-5wt% Ru, no matter what kind of carrier is used or cocatalyst component is present or not present. For the hydrodesulfurization, CoMo or NiMoX may be used as catalyst and gaseous H2 or reformed gas may be used as hydrogenation gas. |
