PURPOSE:To remove a smelling agent of sulfur compound in a hydrocarbon gas, to prevent deterioration in activity of reforming catalyst, and to prolong the life of the catalyst, by setting a desulfurizing catalyst in front of the reforming catalyst kept in the titled reformer. CONSTITUTION:The desulfurizing catalyst 11 of 1-20wt% alkaline earth or alkali metal such as Ca, etc. supported on an expanded porous material of inorganic heat-resistant substance such as codierite, etc. or an integrated molded article of multi-layer thin walls having cross-sectional honeycomb or lattice shape is set in front of the reforming catalyst 8. The desulfurizing catalyst 11 as well as the reforming catalyst 8 are simultaneously preheated to 700-800 deg.C by flame formed on the fire plate 9. After the partial oxidation starts, the desulfurizing catalyst is heated to 400-500 deg.C by the heat generated at the reforming catalyst 8, so a smelling agent consisting of a sulfur compound such as methyl mercaptan, etc. is adsorbed and removed. The sulfur compound accumulated on the desulfurizing catalyst 11 is released and exhausted by the flame formed by the fire plate 9 when a burner is reignited. |
