Abstract

Petroleum distillates (especially gasoline fractions) are reformed to products having high anti-knock values by treatment with a catalyst comprising platinum or palladium and a silica-alumina cracking component having a surface-area of about 10-65 square metres per gram (see Group III). Reforming is carried out at a temperature of 600-1000 DEG F., a pressure of 100-1000 lbs. per square inch, an hourly liquid space velocity of 0.1-10, and in the presence of 1-20 mols. of hydrogen per mol. of hydrocarbon. The maximum isomer yields obtained are substantially independent of temperature so that the temperature may be raised to increase the formation of aromatic hydrocarbons, and higher hydrogen partial pressures may be used to reduce demethanation and carbon formation. The process may be of the fixed, moving, or fluidized bed type, and hydrogen may be recycled.ALSO:A reforming catalyst comprises platinum or palladium and a silica-alumina cracking component having a surface area of about 10-65 square meters per gram. The platinum or palladium content is preferably 0.01-2.5 per cent by weight of the catalyst. The silica-alumina may be derived from natural materials or prepared synthetically, and its surface is reduced, before depositing the platinum or palladium, by steaming at 900-1400 DEG F and atmospheric to 100 lbs. per sq. in pressure or by heating at 1600-1800 DEG F. Regeneration may be effected by treatment with a gas containing 2 per cent oxygen at 900-950 DEG F and increasing the oxygen content up to that of air. The catalyst may also contain low surface area silica-zirconia, silica - alumina - zirconia, silica - magnesia, silica - alumina - magnesia, silica - thoria, silica - alumina - thoria or alumina - boria, and a hydrogenation component e.g. oxides of chromium, molybdenum, tungsten, and uranium, metallic nickel, cobalt, and iron, and molybdates, thiomolybdates, phosphates, tungstates, chromates and borates of nickel, cobalt, and iron. The catalysts are used for reforming petroleum distillates in the presence of added hydrogen to form products with high anti-knock values (see Group IV(b)).
