| abstract | A process for the production of olefins comprises dehydrogenating at least one hydrogen-donor hydrocarbon that is essentially free from olefinic unsaturation, e.g. a paraffin, in the presence of a dehydrogenation catalyst and in the presence of at least one hydrogen-acceptor hydrocarbon that is more highly unsaturated than a mono-olefin, e.g. a diene and/or acetylene, under conditions effective to cause at least part of said hydrogen-donor hydrocarbon to be dehydrogenated and at least part of the hydrogen-acceptor to be hydrogenated. The amount of hydrogen-acceptor is such that there are 0.5 to 20 moles of said hydrogen-donor for each mole of hydrogen-acceptor. Preferably the amount of said hydrogen-acceptor hydrocarbon hydrogenated is such that the heat of hydrogenation of said hydrogen-acceptor hydrocarbon provides at least 25 % of the heat required for dehydrogenation of said hydrogen-donor hydrocarbon. In a preferred form of the invention, a hydrocarbon stream containing the hydrogen-acceptor is a C4 stream from a hydrocarbon cracker and is reacted with a paraffin such as propane or 2-methylpropane as the hydrogen-donor; after separation of propene and/or 2-methylpropene, at least part of the product is recycled to the cracker. |
