|a The results of an initial examination of the feasibility of separation of tritium from gaseous protium-tritium mixtures using vanadium hydride in cyclic processes is reported. Interest was drawn to the vanadium-hydrogen system because of the so-called inverse isotope effect exhibited by this system. Thus the tritide is more stable than the protide, a fact which makes the system attractive for removal of tritium from a mixture in which the light isotope predominates. The initial results of three phases of the research program are reported, dealing with studies of the equilibrium and kinetics properties of isotope exchange, development of an equilibrium theory of isotope separation via heatless adsorption, and experiments on the performance of a single heatless adsorption stage. In the equilibrium and kinetics studies, measurements were made of pressure-composition isotherms, the HT--H₂ separation factors and rates of HT--H₂ exchange. This information was used to evaluate constants in the theory and to understand the performance of the heatless adsorption experiments. A recently developed equilibrium theory of heatless adsorption was applied to the HT--H₂ separation using vanadium hydride. Using the theory it was predicted that no separation would occur by pressure cycling wholly within the ..beta.. phase but that separation would occur by cycling between the ..beta.. and ..gamma.. phases and using high purge-to-feed ratios. Heatless adsorption experiments conducted within the ..beta.. phase led to inverse separations rather than no separation. A kinetic isotope effect may be responsible. Cycling between the ..beta.. and ..gamma.. phases led to separation but not to the predicted complete removal of HT from the product stream, possibly because of finite rates of exchange. Further experimental and theoretical work is suggested which may ultimately make possible assessment of the feasibility and practicability of hydrogen isotope separation by this approach.
