Investigation into the High Selectivity of 2% Ag/gamma-Al2O3 for the Reduction of Oxygen in a H2-rich Ethylene Feed

TAP experiments have studied the catalytic behaviour of  Ag/gamma–Al2O3. The types of active sites, and the intrinsic activity of these sites has been determined. The lifetime of the reactive adsorbed oxygen intermediate has also been determined. These results have been combined with adsorption/desorption rate constants to provide an overview of the catalyst system.
