Abstract
Hydrogen generator with circulation scheme that generates high-purity hydrogen from the solution of sodium borohydride has been developed. In circulation scheme working solution is repeatedly passed through catalytic unit in reactor; the velocity of solution flow and mass transfer processes are more intensive and the entire catalyst is working under approximately the same conditions. Alumina-supported Pt-, Pd-, and Ni-granulated materials have been used as model catalysts during performance testing of the hydrogen generator. Instead of water-alkaline solution it is proposed to use sodium metaborate solution saturated at room temperature as a solvent and stabilizer to prepare working solutions. Optimal parameters of working process (working solution composition, temperature, pressure) were defined. Technical specifications of the generator allow achieving hydrogen performance up to 3 Nm3/h and higher.
