Abstract
Processes and apparatus for isomerizing hydrocarbons are provided. The process comprises providing a feed stream comprising C5, C6 and C7+ hydrocarbons. The feed stream is separated to produce a first stream rich in C5 and C6 hydrocarbons and a second stream rich in benzene and C7+ hydrocarbons. The first stream is isomerized in the presence of isomerization catalyst and hydrogen in an isomerization zone under isomerization conditions to produce an isomerized stream. The second stream is contacted with a benzene saturation catalyst at benzene saturation conditions to produce a saturation effluent stream comprising cyclohexane.
