Abstract
The benzene content in a gasoline pool is reduced by an isomerization process that splits a benzene-containing C.sub.4 -C.sub.6 feedstream between at least two reaction zones and combines the feed fractions with effluent streams. The splitting of the feed stream distributes the heat of reaction over two reactors and lowers the relative exotherm. The lower exotherm for benzene saturation permits higher benzene feeds to be processed without reducing product quality.
