The development of catalytic materials for the efficient combustion of light alkanes is fundamentally important for both automotive pollution control and the control of emissions produced from bio-fuel combustion. The presence of trace gas-phase SO2 is known to promote low temperature propane combustion over conventional Pt/Al2O3 combustion catalysts, however, there have been no systematic efforts to isolate the respective roles of support and metal, and it remains unclear, which plays the dominant role in this unusual phenomenon. Light alkane combustion over Pt/Al2O3 using pre-sulfated alumina supports to tune the physicochemical catalyst properties was presented. Support sulfation significantly enhanced ethane combustion, and improved methane and propane light-off. Catalyst activity increased with Pt loading, while the magnitude of sulfate promotion scales with alkane chain length. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
