Zusammenfassung:1,179,120. Pt on C catalysts. FARBENFABRIKEN BAYER A.G. 16 Dec., 1966 [28 Dec., 1965; 28 Nov., 1966], No. 42796/69. Divided out of 1,179,119. Heading B1E. Catalysts comprising finely divided Group VIII precious metal supported by a mixture of graphite and 10-50% activated carbon are used in the production of hydroxylammonium salts by reduction of NO with hydrogen in aqueous acid solution. In examples Pt is supported on 80% graphite and 20% activated carbon.
