摘要：NOVELTY - A naphtha absorption and separation method involves filling naphtha with 5A molecular sieve in a simulated moving bed adsorption separation device under liquid phase conditions. The mixture is passed through continuous processes of liquid-solid adsorption separation to give desorption effluent and raffinate effluent, where the effluent of the desorption effluent and raffinate are obtained after recovery of desorption of oil rich n-paraffins and non-normal paraffins-rich raffinate oil, and the desorbed oil comprises (in wt.%) n-alkanes (90-100). USE - Method for absorption and separation of naphtha. ADVANTAGE - The method ensures absorption and separation of naphtha in a low operating temperature, with continuous operation, high yield, low consumption desorption, high product yield and high utilization rate of the molecular sieve adsorption separation method.
