摘要: The conversion of sulfur contaminated syngas to CH3OH over Pd/CeO2 and Pd/Al2O3 catalysts was studied at 513 K and 3.0 MPa. While the same 16.5% CH3OH yield (CO basis) was obtained over Pd/CeO2 in sulfur-free and contaminated (30 ppm H2S) syngas, the activity of Pd/Al2O3 declined rapidly with only 3 ppm H2S present yielding 2.2% CH3OH after 100 h. H2S addition also reduced the CO2 and hydrocarbon yields over Pd/CeO2 to less than 2% in total. XPS, XRF and XRD analysis suggests that H2S is not trapped but oxidized to some extent over Pd/CeO2.
