Abstract

Preparation and Catalytic Properties of Cerium Hydride. -CeH0.3 is formed at 523 K and atmospheric pressure from the elements using a pulse-flow technique. The reaction of cerium hydride with small molecules under near atmospheric pressure and 523 K is monitored in a series of pulse-flow reactions. The hydride does not adsorb or react with either CO or CO2. There is extensive reaction with O2 resulting in water formation and a significant rise in temperature. The interaction between CeH0.3 and MeOH gives rise to adsorption and, at low levels, CH 4 and H 2 . Propyne hydrogenation also occurs over cerium hydride but a hydrogen source other than the hydride is required. -(JACKSON*, S. D.; KELLY, G. J.; VASS, E. M.; J.
