High pressure Water Gas Shift performance over a commercial non-sulfide CoMo catalyst using industrial coal-derived syngas

摘要: Abstract High pressure Water Gas Shift performance over a commercial non-sulfide CoMo catalyst was studied in bench scale set-up, using an industrial coal-derived syngas feed. CO conversion showed important dependence on both reaction temperature and space velocity but remained almost constant with increasing H2Ov/CO molar ratios. Hydrogen selectivity the same trend although it enhanced The effect of activation method also studied. Despite catalysts have been widely considered as non-active for WGS reaction, surprisingly high comparable to that attained by sulfide one, displayed this range conditions However, still resulted lower values if compared pre-sulfide one.
