ABSTRACT:
Process for the isomerization of a hydrocarbon feed containing hydrocarbons comprising at least 4 carbon atoms, which process comprises isomerizing a hydrocarbon stream; separating the isomerisate thus obtained into a hydrogen-containing gas and a hydrocarbon effluent; separating from the hydrocarbon effluent a product stream containing branched hydrocarbons, leaving non-product hydrocarbons, and passing at least part of these hydrocarbons again to the isomerization step, in which process at least part of the feed is added to at least part of the isomerisate before the isomerisate is separated into the hydrogen-containing gas and the hydrocarbon effluent.
