Kim (assigned to Standard Oil of Indiana, Chicago, Ill.). Catalyst and Hydrocarbon Conversion Process. U.S. Pat. 4,136,060, Jan. 23, 1979. RHENIUM superior to that of nickel. A study of the effect of NB concentration and hydrogen pressure on the activity and stability of a 5% rhenium catalyst (percent metal on charcoal) showed that in the concentration range of 10% to 50% NB, the reaction proceeded almost at a constant rate, with apparent activation energy of about 7,000 calories per mole. Total conversion of NB was obtained at 180~ to 200CC. A considerable advantage of rhenium catalysts in NB reduction is their high selectivity. Being superior to palladium and nickel catalysts in productivity, the 5% rhenium catalysts showed a high working capacity over a wide range of contact loads, which is of great importance in its industrial use in columntype contact reactors. A comparison of the relative costs of rhenium-base catalysts with the cost of nickel-, platinum-, and palladium-base hydrogenation catalysts on granulated carbon showed that the 5% rhenium catalyst is competitive with 1% platinized carbon. The 2% rhenium catalyst is a promising substitute for 0.5% platinum or 2% palladium catalysts in the reduction of temperature-stable nitrocompounds.'~ A patent was applied for in 1978 on a catalytic composition for the reforming of petroleum hydrocarbons. The catalyst consists of 0.1 to 2.0 weight-percent rhenium and 0.1 to 2.0 weight-percent gallium. The catalyst was supported on a solid, porous, refractory, inorganic oxide material.
