Method for producing metal borohydride from metal boron oxide

Abstract

Metal borohydride, Me(BH4)n, is produced from metal boron oxide, Me(BO2)n, in which Me is a metal or a molecule that shows metal-like behaviour and can act as a metal, and n is an integer that can be associated with the valence of the metal, wherein in a first fluidized bed step the metal boron oxide is provided in a first fluidized bed. The first fluidized bed is fluidized using a gas selected from at least one of nitrogen, N2, gas and a noble gas, under such circumstances, especially pressure and temperature, that oxygen atoms are removed from the metal boron oxide to provide metal boron, MeBn, particles, possibly ions. In a subsequent second fluidized bed step the metal boron particles are provided in a second fluidized bed that is fluidized using hydrogen, H2, gas under such circumstances that hydrogen chemically reacts with the metal boron particles to provide metal borohydride.
