CATALYST (VARIANTS), METHOD OF PREPARATION THEREOF, AND A METHOD FOR PRODUCTION OF HYDROGEN FROM HYDRIDE SOLUTIONS Russian patent published in 2008 - IPC B01J23/78 B01J23/89 B01J21/00 B01J37/02 C01B3/06 

FIELD: hydrogen production processes.

SUBSTANCE: invention relates to catalysts for hydrolysis of hydride compounds to produce pure hydrogen for being supplied to power installations, including fuel cells. Invention provides catalyst for production of hydrogen from aqueous or water-alkali solutions of hydride compounds containing platinum group metal deposited on complex lithium-cobalt oxide and, additionally, modifying agent selected from series: titanium dioxide, carbon material, oxide of metal belonging to aluminum, magnesium, titanium, silicon, and vanadium subgroups. According to second variant, catalyst contains no platinum group metal. Described are also catalyst preparation method (variants) and hydrogen generation process, which is conducted at temperature no higher than 60°C both in continuous and in periodic mode. As hydrogen source, sodium borohydride, potassium borohydride, and ammine-borane can be used.

EFFECT: increased catalyst activity at environmental temperatures (from -20 to 60°C), prolonged time of stable operation of catalytic system, and reduced or suppressed platinum metals in composition of catalyst.
