1317964 Catalyst composition GULF RESEARCH & DEVELOPMENT CO 12 Aug 1970 [25 Aug 1969] 38804/70 Heading B1E [Also in Division C5] A catalyst composition comprises solely alumina, cobalt (1-4 wt% based on the total catalyst) molybdenum (4-12 wt%) and silver or copper (0.1-6 wt%) the metals optionally being in the form of oxides. The catalyst is formed by grinding together oxides of the above components or by impregnating the alumina with solutions of compounds of the other metal components, drying and then calcining, e.g. at 400-600‹C.
