Patent number: 5651917Abstract: An acidic aqueous medium for contacting and purifying a gas-phase stream by oxidation of a contaminant contained therein. The medium comprises an aqueous medium which contains redox-effective quantities of (1) silver(I) oxidation catalyst, (2) hydrogen peroxide oxidant, (3) silver metal-reoxidation co-catalyst ingredient which forms a cyclic complex with the hydrogen peroxide oxidant, and (4) oxidation-resistant acid. The acidic aqueous medium provides an integrated functionality of components (1) through (4) for the efficient cascade oxidation of a contaminant containing gas stream, and the continuous regeneration of the reduced silver metal catalyst back to the silver(I) oxidation state.Type: GrantFiled: August 10, 1995Date of Patent: July 29, 1997Assignees: Philip Morris Incorporated, Philip Morris Products, Inc.Inventors: Charles T.
