Abstract: A method for separating C8 - C24 carbon number range straight chain hydrocarbons from hydrocarbon mixture employing a molecular sieve selective adsorption process comprising an adsorption cycle and a desorption cycle operated in the vapor phase at an elevated temperature and super-atmospheric pressure wherein a vaporized desorbent hydrocarbon is employed in the desorption cycle. Also a method for treating a selective adsorbent effluent to recover desorbent hydrocarbon for recycle to the selective adsorption process.

Abstract: A MOLECULAR SIEVE SELECTIVE ADSORPTION PROCESS FOR SEPARATING NON-STRAIGHT CHAIN HYDROCARBONS FROM A C5-C9 CHARGE MIXTURE OF STRAIGHT CHAIN AND NON-STRAIGHT CHAIN HYDROCARBONS INCORPORATING A CHARGE VAPORIZATION SYSTEM WHEREIN LIQUID CHARGE IS PARTIALLY VAPORIZED IN A FIRST HEATING ZONE AT AN ELEVATED PRESSURE, WHEREIN PARTIALLY VAPOR-

IZED CHARGE IS TOTALLY VAPORIZED BY ADIABATIC EXPANSION IN AN EXPANSION ZONE EXTERIOR TO THE HEATING ZONE, AND WHEREIN THE VAPORIZED CHARGE IS SUPERHEATED IN A SECOND HEATING ZONE PRIOR TO ADMISSION INTO AN ADSORPTION ZONE.
