ABSTRACT:
A process for the isomerization of acyclic hydrocarbons and alkylaromatic hydrocarbons is disclosed. The mixed-phase feed stream is heated and the liquid-phase portion of the feed stream is simultaneously vaporized by indirect heat exchange against the effluent of the reaction zone. Prior to this exchange, the effluent of the isomerization zone is heated in a fired heater to a temperature above that employed in the reaction zone. The inventive concept eliminates the need to pass mixed-phase feed streams through fired multi-pass heaters.
