1496959 Catalysts for hydrocracking oils UOP Inc 2 May 1975 [3 May 1974] 18366/75 Heading C5E [Also in Division B1] Hydrocarbon feeds are hydrocracked using a catalyst comprising a carrier of co-gelled silicaalumina consisting of 57-43% wt. silica and 43-57% wt. alumina and containing, on an elemental basis, 7-9% wt. of a nickel component and 17-19% wt. of a tungsten component. The hydrocarbon feed may be a naphtha or gasoline boiling range distillate (to give LPG) or a heavier charge, e.g. kerosenes, light gas oils, heavy gas oils, full boiling range gas oils and "black oils". Specified reaction conditions include use of a fixed bed with a hydrogen/oil vol. ratio of 356-3560 (2000-20,000 SCFB), a LHSU of 0À2-15À0, a pressure of 6À4-205 atm. (50-3000 p.s.i.g.) and a catalyst bed inlet temperature of 177-427‹ C. (350-800‹ F). The example relates to the treatment of a light vaccum gas oil of specified properties. |
