摘　　要：采用5A分子筛为吸附剂,在固定床装置中将石脑油中的正构烷烃和非正构烷烃进行吸附分离,得到富含正构烷烃的脱附油和正构烷烃含量很少的吸余油。探讨了吸附温度、进料空速、脱附时所需的脱附温度、进料空速以及中间油切割时间对分离效果的影响。结果表明,在吸附温度为260℃,进料空速为1.0 h-1,脱附温度为350℃,进料空速为150 h-1时分离效果良好。The absorption-separation of n-alkanes and non-normal alkanes in naphtha are performed by using 5A zeolite in a fixed-bed unit. The resulting desorption oil enriched in n-alkanes and raffinate oil enriched in non-normal alkanes are obtained. The influences of adsorption temperature, space velocity, desorption temperature and desorption space velocity on the separation are studied. The good separation effect can be achieved under the following conditions ： 260℃ of adsorption temperature, 1.0 h-1 of space velocity, 350℃ of desorption temperature and 150 h- 1 of desorption space velocity.
