Research Progress on Removal of Oxygenates in Fischer-Tropsch Oil by Adsorption

The oxygen-containing compounds in Fischer Tropsch synthetic oil greatly affect the downstream deep processing of hydrocarbons, and effective removal is required. Compared to traditional removal technologies such as hydrogenation deoxygenation, solvent extraction, and extraction distillation, adsorption deoxygenation technology has the advantages of low cost, mild operating conditions, easy removal and recovery, and minimal impact on oil quality. Therefore, adsorption deoxygenation technology has devel‐ oped rapidly in various removal processes and has become a research hotspot in the current Fischer Tropsch oil deoxygenation. Adsorbents are the core of adsorption deoxygenation technology. Therefore, this article briefly introduces the adsorption mechanism and summarizes the research progress of adsorbents widely used in recent years, such as silica gel, alumina, molecular sieves, and metal organic frameworks, in adsorbing oxygen-containing compounds in Fischer Tropsch synthetic oils. And provide reference suggestions for further adsorption and deoxygenation directions in the future.
