Abstract
Processes for increasing an octane value of a gasoline component by dehydrogenating a stream comprising Chydrocarbons and methylcyclohexane in a first dehydrogenation zone to form an intermediate dehydrogenation effluent, and then dehydrogenating the intermediate dehydrogenation effluent in a second dehydrogenation zone to form a Cdehydrogenation effluent. The Cdehydrogenation effluent has an increased olefins content compared to an olefins content of the intermediate dehydrogenation effluent. The first dehydrogenation zone is operated under conditions to convert methylcyclohexane to toluene and minimize cracking reactions. The intermediate dehydrogenation effluent may be heated before being passed to the second dehydrogenation zone.
