Abstract
A process for the dehydrogenation of a dehydrogenatable hydrocarbon by contacting the hydrocarbon with a liquid comprising an alkali metal in a dehydrogenation zone to produce a dehydrogenated hydrocarbon and an alkali metal halide. The resulting alkali metal hydride is heated to produce a heated liquid alkali metal and hydrogen. The heated liquid alkali metal is recycled to the dehydrogenation zone to provide heat and elemental metal.
Claims7
A process for the dehydrogenation of a dehydrogenatable hydrocarbon which process comprises:
- (a) contacting said dehydrogenatable hydrocarbon with a liquid comprising an alkali metal in a dehydrogenation zone at dehydrogenation conditions to produce a dehydrogenated hydrocarbon and an alkali metal hydride;
- (b) removing and heating at least a portion of said alkali metal hydride from said dehydrogenation zone to produce a heated liquid alkali metal and hydrogen;
- (c) recycling at least a portion of said heated liquid alkali metal to said dehydrogenation zone in step (a);
- and
- (d) recovering said dehydrogenated hydrocarbon.
