摘　　要：为了实现石脑油的高效资源化利用,需开发石脑油高效分离技术。简述了石脑油正/异构烷烃吸附分离原理及分离技术现状,介绍了新型吸附剂材料的研发进展,包括金属有机框架材料(MOFs)、沸石咪唑框架材料(ZIFs)、碳分子筛(CMS)、中空沸石分子筛等,阐述了新型吸附材料对正构烷烃的分离效果和分离机理,探讨了新型吸附剂、膜分离技术和吸附-膜分离耦合技术用于分离石脑油中正/异构烷烃的可行性,展望了新型正/异构烷烃分离技术,以期为石脑油高效资源化利用提供新途径。To achieve the optimum utilization of naphtha resource, high efficient separation methods need to be explored for naphtha. In this review, the adsorption mechanism and recent technology for n-alkanes separation are briefly discussed. New types of adsorbents, including metal organic frameworks （MOFs）, zeolite imidazole frameworks （ZIFs）, carbon molecular sieve （CMS） and hollow zeolite molecular sieve, are introduced. Besides, the separation performance and separation mechanism of new adsorbents for n-alkanes separation are discussed. The feasibilities of new adsorbents, membrane separation technology and adsorption-membrane separation coupling technology for the separation of n-/iso-alkanes are also discussed. Novel technologies for n-alkanes separation from naphtha are proposed, which may offer new approaches for the efficient utilization of naphtha resource.
