    摘要： 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.

    摘要： A process for separating at least two liquid phases which are at least partially non miscible is characterized in that after reacting, a polyphase effluent is settled in at least two distinct settling zones arranged in parallel, each of these settling zones containing at least one settler. The feed to be treated is sent to reactor R via a means for circulating fluids P via line 1. The effluent leaves the reactor via line 2 and is separated into two fractions. One fraction is sent to a settling zone a) via line 3; the other fraction is sent to a settling zone b) via line 4. The heavy phase from settling zone a) is sent to the reactor via line 7 and the heavy phase of the settling zone b) is sent to the reactor via line 6. The light phase from settling zone a) is sent to line 8, and rejoins fresh feed supply line 1. The light phase from settling zone b) is evacuated from the circuit via line 5.

    摘要： Continuous process for converting hydrocarbons in the presence of a granular catalyst including a metal from group VI a, VII a or VIII, deposited on a carrier, comprising passing a charge of hydrocarbons with hydrogen through a series of at least two vertical catalytic zones in which the catalyst bed moves progressively downwardly, withdrawing progressively the catalyst from the bottom of the last catalytic zone, and reintroducing the same, after regeneration, at the top of the first catalytic zone.
