ABSTRACT:
A process for the isomerization of normal olefinic hydrocarbons is disclosed. The feed stream is passed through a first reaction zone and is then cooled sufficiently to cause the condensation of from about 1 to 25 mole percent of the hydrocarbons in the isomerization zone effluent stream. The uncondensed portion of the effluent of the first reaction zone is heated and passed through a second reaction zone which is maintained at a lower temperature than the first reaction zone. The product isomer is recovered from the effluent of the second reaction zone.
