Özet
Kinetics of low temperature CO oxidation was studied in hydrogen-rich streams using cobalt (1.25 wt %) and ceria (1.25 wt %) promoted 1.4 wt % Pt/Al2O3 catalyst prepared by incipient-to-wetness impregnation. Intrinsic kinetic data were obtained in the initial rate region in a microflow reactor operating in differential mode using eight different sets of CO and O2 concentrations in 60% H2 and He as balance. The experiments were conducted at 110°C, both in the absence and the presence of 25% CO2 and 10% H2O, and at for two space times. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
