Abstract

A reforming and isomerization process has been developed. A reforming feedstream is charged to a reforming zone containing a reforming catalyst and operating at reforming conditions to generate a reforming zone effluent. Hydrogen and an isomerization feedstream is charged into an isomerization zone to contact an isomerization catalyst at isomerization conditions to increase the branching of the hydrocarbons. The isomerization catalyst is a solid acid catalyst comprising a support comprising a sulfated oxide or hydroxide of at least an element of Group IVB, a first component being at least one lanthanide series element, mixtures thereof, or yttrium, and a second component being a platinum group metal or mixtures thereof. The reforming zone effluent and the isomerization zone effluent are each separated to form a light ends stream and a product stream. The light ends streams are combined for processing in a net gas re-contacting zone.
