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.
