Properties of LaNi_4.3Al_0.7 Applied in Separating Hydrogen from Coke Oven Gas

Abstract:

Nowadays hydrogen as an important source of energy is still produced from fossil fuel processing largely, hence the separation of hydrogen from the gas mixture with high recovery ratio and purity arises as an important issue. In this paper we proposed a hydrogen recovery/production process from half-coke oven gas, and the material LaNi_4.3Al_0.7 was considered for use due to its low plateau pressure and good resistance to impurities. We use a Sieverts type volumetric apparatus to investigate the material properties,including P-C-T properties and hydriding/ dehydriding kinetics under different conditions. Based on the results obtained, the feasibility of using the material for gas separation purpose was discussed.Keywords: Gas separation; metal hydride; reaction kinetics; P-C-T properties; Sieverts method
