Abstract:

Separation and purification of structurally similar olefin/paraffin/alkyne mixtures are vital important processes in chemical industry. Light hydrocarbons have similar physical and chemical properties, and only have minor difference in carbon number and degrees of unsaturation. Traditional cryogenic distillation usually exhibit low selectivity for structurally-related hydrocarbons and thus are energy-intensive processes. The diversity and designability of metal-organic frameworks (MOFs)/porous coordination polymers (PCPs) makes them can recognize the minor difference of different hydrocarbon molecules. Therefore, many significant progresses have been made in hydrocarbon separation with microporous MOFs as novel adsorbents. In this review, the recent progresses of MOFs in the adsorptive separation of olefin/paraffin/alkyne mixtures (C2 and C3) were systematically summarized. Additionally, the current problems and the future research directions to address challenges in the field of separation of light hydrocarbons with MOFs were discussed.

Key words: light hydrocarbons, adsorption, separation, olefin, alkane, alkynes, metal-organic frameworks

摘要:

烯烃、烷烃和炔烃等结构相似物的高效分离是石油化学工业可持续发展的关键过程之一。低碳烃化合物结构和性质相近,仅在碳数和不饱和度存在微小差异,传统低温精馏过程选择性低、能耗高。金属有机框架材料/多孔配位聚合物(MOF/PCP)的结构多样性及可设计性使其可以精确识别相似物分子间的微小差异,在低碳烃分离领域取得重要进展。综述了金属有机框架材料在碳二/碳三的烯烃、炔烃和烷烃分离体系中取得的最新进展以及分离机理,探讨了金属有机框架材料在低碳烃吸附分离研究中存在的问题和发展方向。
