Abstract

Sodium borohydride as a hydrogen storage material for portable application has attracted much attention. A newly designed reactor with a toroidal tube distributor has been developed to generate hydrogen from sodium borohydride accelerated by cobalt(II) salts. The effects of the cobalt solution flow rate, the cobalt(II) acetate concentration, as well as the reaction temperature on hydrogen generation are discussed. The newly designed reactor successful reduced the hydrogen generation startup time and improved the water distribution. The results indicate that the startup time is decreased with an increase in (1) the concentration of the cobalt(II) acetate solution, (2) the reactor temperature and (3) the cobalt salt solution flow rate. The hydrogen yield increases with increase in cobalt(II) acetate concentration and reached a maximum at 1 wt %; further increases in the catalyst loading results in a decrease of the hydrogen yield. Furthermore, the hydrogen yields > 99 % is achieved using the novel reactor.
