ABSTRACT:
A process using hydrogen dissolving metals, alloys and intermetallic compounds to drive otherwise thermodynamically unfavorable dehydrogenation reactions is disclosed. The process comprises the steps of selecting an organic reactant comprising carbon and hydrogen, and exposing the organic reactant to a material at a temperature and pressure sufficient to remove at least one hydrogen from one said organic reactant and to form a material hydride, the material being selected from the group of metals, alloys and intermetallic compounds having a negative standard free energy of formation for a hydrided product MH.sub.y, where M is the material, H is hydrogen and y is a non-zero number between 0 and about 4 and represents the total hydrogen to material atom ratio wherein the standard free energy change for the reaction of the organic rectant in the present of the material to remove at least one hydrogen atom therefrom and from the material hydride is negative.
