Use of hydride phases based on intermetallic compounds as catalysts for hydrogenation and hydrogenolysis
Investigation of the use of intermetallic hydride phases as effective catalysts of hydrogenation by molecular hydrogen is proceeding in two directions: (1) study of the catalytic activity of hydride phases in hydrogenation reactions of olefin and acetylene hydrocarbons and organic compounds containing multiple nitrogen-carbon bonds, and (2) feasibility on the use of hydride phases as catalysts hydrogenating carbon monoxide and in ammonia synthesis, at 250 to 350/sup 0/C and pressures below 100 atm. The first group of reactions takes smoothly at 20 to 100/sup 0/C and 1 to 50 atm hydrogen pressure. The hydrogenation reaction of multiple carbon-carbon and carbon-nitrogen bonds does not require any special catalyst selection. The second group of reactions requires considerably more energy for activating the CO and N/sub 2/ molecules. Hydride phases of transition metal and rare earth metal intermetallic compounds are used as catalysts.
