Improved process for olefins to gasoline conversion.

摘要

An improved process is described for the conversion of olefins to gasoline in contact with zeolite type cataylst. Improvement comprises incorporating a fractionation step in the separation of the effluent stream from the olefins to gasoline conversion reactor such that LPG components in the effluent stream are separated and recovered as well as a stream comprising C5+ gasoline range boiling liquids. In a preferred embodiment the fractionation step is integrated with FCC unsaturated gas plant fractionators providing advantages in the utilization of common fractionation equipment resulting in significant reduction in process energy and investment requirement.
