Abstract
The present invention relates to a process for the production of olefins from a hydrocarbon cut, comprising a step for separating at least one paraffin contained in the hydrocarbon cut, a step for dehydrogenating the paraffin and a step for purifying the hydrogen produced during dehydrogenation, at least a part of that hydrogen being recycled to the dehydrogenation step. The invention is of particular application to the preparation of olefins containing 3 to 5 carbon atoms per molecule from a C.sub.3 to C.sub.5 hydrocarbon cut containing at least one paraffin.
