摘要:

研究费托合成油的高值化利用是煤制油产业可持续发展,赋能碳达峰、碳中和的重要途径。费托合成油适合作为生产α-烯烃的原料,而油中有机酸、醇、醛、酮、酯等含氧化合物的脱除是α-烯烃分离精制的基础。脱除方法主要有吸附、加氢、精馏、溶剂萃取等,其中吸附法具有操作简单、可再生、深度除杂等优点,尤其适用于微量含氧化合物的完全脱除。介绍了分子筛、硅胶、活性氧化铝、树脂、金属有机骨架化合物(MOFs)等吸附剂脱除含氧化合物的原理,综述了各类吸附剂脱除费托合成油中含氧化合物的研究进展。结合文献数据,比较了各类吸附剂的吸附效果,并对脱除含氧化合物工艺的研究方向提出了建议。

Abstract:

Research on high value utilization of Fischer-Tropsch(F-T) synthetic oils is an important way for sustainable development of coal-to-oil industry, reaching carbon peak and realizing carbon neutralization. F-T synthetic oils is suitable to be the feedstock of producing α-olefin, and the removal of oxygenated compounds in oil, such as organic acids, alcohols, aldehydes, ketones, esters, is the basis of α-olefin separation and refining. The main removal methods include adsorption, hydrogenation, distillation, solvent extraction and so on. The adsorption method has the advantages of simple operation, regenerative and deep impurity removal rate, especially suitable for the complete removal of trace oxygenated compounds. In this paper, the principle of removing oxygenated compounds by adsorbents such as molecular sieve, silica gel, activated alumina, adsorption resin and metal-organic skeleton compounds(MOFs) was introduced, and the research progress of various adsorbents for the removal of oxygenated compounds from F-T synthetic oils was reviewed. Combined with literature data, the adsorption effects of various adsorbents were compared, and some suggestions on the research direction of the process of removing oxygenated compounds were also put forward.
