ABSTRACT:
A process is provided for the hydrogenation of benzene and the isomerization of a light naphtha feedstock consisting essentially of a stream having a boiling range of from about 50.degree. F. to about 240.degree. F. comprising the steps of contacting the light naphtha feedstock at isomerization conditions in an isomerization reaction zone with an isomerization catalyst in the presence of hydrogen and producing an isomerization reaction zone effluent, combining the isomerization reaction zone effluent with a supplemental benzene-containing stream comprising at least 1 weight percent benzene and forming a hydrogenation zone feedstock, and hydrotreating the hydrogenation zone feedstock at hydrogenation conditions in a hydrogenation reaction zone with a hydrogenation catalyst in the presence of hydrogen for producing an isomerate product comprising less than 0.1 weight percent benzene.
