Abstract

Aliphatic or alicyclic C1 to C20 hydrocarbons are dehydrogenated in a process wherein the hydrogen produced is separated from the gaseous reaction mixture by contacting the reaction mixture with one side of a membrane selectively permeable to hydrogen, the unconverted reactants being further reacted to produce more hydrogen. There is reference to the dehydrogenation of propane and butane to olefins, isopentane to isoprene and cyclohexane to benzene.ALSO:<PICT:1039381/C1/1> Hydrogen is produced by a gas phase chemical reaction in a process which includes the step of contacting the reaction mixture with one side of a membrane selectively permeable to hydrogen to separate a diffused gaseous hydrogen stream from the undiffused gaseous reaction mixture containing unconverted reactant(s), and further reacting the unconverted reactant(s) to produce more hydrogen. Examples relate to (1) the dissociation of ammonia at 800-1200 DEG F. using as catalyst, for example, platinum, palladium, rhodium or ruthenium packed into reaction chamber 49 (Fig. 4), and collecting at 55 hydrogen which has diffused through the walls of diffusion coil 52, made for example of palladium-25% silver alloy; (2) dissociation of ammonia in a multi-stage reaction system, each reactor being operated at 850 DEG F. and 40 atmospheres, and a hydrogen diffusion unit being provided between each reaction stage (for example as in Fig. 2, not shown); (3) steam reforming of naphtha at 1200 DEG F. and 14 atmospheres; (4) steam reforming of propane at 1300 DEG F. and at 1470 DEG F. Reactions generally discussed are the dehydrogenation of C1 to C20 hydrocarbons; steam-reforming of C1 to C20 hydrocarbons at 1050 DEG to 1800 DEG F. and 5 to 300 atmospheres; the CO shift reaction.
