Abstract

1361190 Regenerating oxidation catalysts LAPORTE INDUSTRIES Ltd 15 Nov 1971 [24 Nov 1970] 55787/70 Heading B1E [Also in Division C2] Catalysts comprising silver, and optionally copper and/or gold, and X germanium, tin, lead, nitrogen, phosphorus, arsensic antimony and/or bismuth are regenerated by subjecting surface of the catalyst to reducing conditions until the selectivity as an oxidation catalyst increases to reach or approach asymptotically a maximum value. The reducing agent may be hydrogen or the compound to be oxidised.
