摘要:

燃油中的含硫化合物燃烧产生的SOx是环境污染的主要来源之一,近年来随着环保法规的日趋严格,油品的超深度脱硫已成为当务之急。吸附脱硫(ADS)因具有低能耗、条件温和、操作简单和反应高效等优点,被认为是实现深度脱硫的最有前景的技术之一。目前,作为多孔材料族的新成员,金属有机骨架(MOFs)已显示出良好的吸附脱硫性能。本文综述了近10年来MOFs在吸附脱硫中的最新研究成果。首先,简述了MOFs的不同分类,包括IRMOFs、ZIFs、MILs、PCNs、HKUST-1、UiOs、CPOs等类型,详细介绍了每一类MOFs中具有代表性的材料及其复合物在吸附脱硫中的研究和应用进展,对每种材料的吸附脱硫效果及回收再生、循环利用情况进行了分析;然后总结了不同MOFs的吸附脱硫机理,概述了MOFs吸附剂的稳定性;最后,指出了MOFs在今后应用中应着重解决的问题,并对MOFs在吸附脱硫领域的应用前景进行了展望。

Abstract:

SOx from the combustion of sulfur compounds in fuel is one of the main sources of environmental pollution. In recent years, with the increasingly strict environmental regulations,deep desulfurization of fuel has become a top priority. Adsorption desulfurization (ADS) has the advantages of low energy consumption, mild conditions, simple operation and efficient reaction. It is considered to be one of the most promising technologies for achieving deep desulfurization. Currently, as a new member of porous material family, metal-organic frameworks (MOFs) have shown good desulfurization performance. This article reviewed the most up-to-date progress of MOFs in adsorption desulfurization in the past 10 years. Firstly, the different types of MOFs such as IRMOFs, ZIFs, MILs, PCNs, HKUST-1, UiOs and CPOs were described. The representative materials in each types of MOFs were introduced in detail, and the research and application progress of MOFs in adsorption desulfurization were summarized. The desulfurization effect, regeneration and recycling of MOFs were analyzed. Then, the mechanisms of adsorption desulfurization and the stability of MOFs were summarized. Finally, the key problems of the applications of MOFs to be solved in future were also mentioned. The future development prospects of MOFs in fuel adsorption desulfurization were prospected.

Key words: metal-organic frameworks, adsorption desulfurization, fuel
