Abstract

Experimental results of absorption and desorption reactions of cerium-doped NaAlH4 in an air-heated tank are presented. With a hydrogenation pressure of 100 bars a maximum capacity of 3.5 wt% is reached after 4 h during absorption experiments. For desorption, after 5 h reaction a capacity of 3.5 wt% is reached at a pressure of 4 bars and 150°C. Additionally, the kinetics of the material and the tank geometry have been modelled and the influence of cooling heat transfer and inlet hydrogen temperature are analyzed.
