1470917 Reforming catalysts COMPAGNIE FRANCAISE DE RAFFINAGE 12 Feb 1975 [13 Feb 1974] 6026/75 Heading C5E [Also in Division B1] Hydrocarbon feeds are hydroreformed in contact with a catalyst comprising a refractory mineral oxide carrier comprising combined halogen and, in free or combined form, 0À02-2% wt. of at least one platinum-group metal, 0À02- 2% wt. of at least one of Mo, Cr and Mn, 0À02-2% wt. of tin and, optionally, 0À05-0À5 wt. per cent sulphur. The examples describe (i) the hydroreforming of n-heptane at 520‹ C., 1 atmosphere pressure, a LHSV of 0À5 or 2 and a hydrogen/heptane molar ratio of 18 : 1 or 5 : 1 to give a specified range of products, and (ii) the hydroreforming of a charge of boiling range 76-151‹ C. of specified composition at 480‹ C., a LHSV of 2 and hydrogen/hydrocarbon molar ratio of 5 : 1. |
