ELEMENTAL MAGNESIUM PRODUCTION BY CARBOTHERMIC REDUCTION FOR USE IN THE REGENERATION OF HYDROGEN STORAGE COMPOUNDS

摘要

The invention provides a process for the production of elemental' magnesium from feed materials containing magnesium oxide and carbon, said process comprising: exposing excess magnesium oxide and carbon to a high temperature reaction zone, in the presence of a catalyst, which is optionally supported, for disproportionation of carbon monoxide back to carbon and carbon dioxide, wherein said magnesium oxide and carbon react at a temperature of at least 1100. OC in said reaction zone to produce gaseous magnesium and carbon monoxide, and.removing said gaseous magnesium and carbon dioxide from said reaction zone. The obtained magnesium powder is used in a process for synthesizing or regenerating hydrogen storage compounds such as metal borohydrides.
