Method for producing metal borohydride and molecular hydrogen

摘要

Method of generating a metal borohydride and / or H _2. This method comprises the following steps: B. generating metal borohydride in a synthetic process where H ₂ is a reactant and the reaction further requires metal hydroxide and boron oxide or further metal boron oxide; A metal borohydride and H ₂ O produced in step A is a step of generating of H ₂ in a chemical reaction process is a reactant, the amount of H ₂ produced in step B, in each step B and A A step greater than the amount of H ₂ required as a reactant in step A for the same amount of metal borohydride as reactant and reaction product; The process includes supplying H ₂ generated in the process C to the process A and repeating the processes A, B, and C. Steps A, B, and C are repeated, each extracting a portion of the metal borohydride and / or H ₂ produced in steps A and B while leaving a certain amount of metal borohydride and H ₂ , respectively.
