Abstract

Processes for the production of a gasoline blend. A C7 portion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the C7 saturated hydrocarbons are convert to C7 olefins. The C7 olefins have a higher octane number than the C7 saturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The C7 olefins can be blended in a gasoline pool. C5 and C6 hydrocarbons can be isomerized and dehydrogenated as well, separately or with the C7 components.
