摘要：
Low-temperature Fischer-Tropsch (LTFT) synthesis technology has attracted much attention in the coal chemical industry owe to its advantages of good product quality, low reaction energy consumption, large production capacity and more selectable catalysts species. Wax oil obtained from low-temperature Fischer-Tropsch synthesis can be refined to obtain high-quality clean oil by hydrocracking process. In this work, the product characteristics of Fischer-Tropsch synthesis was described, the reaction characteristics of wax oil hydrocracking, the reaction progress of wax oil and the carbocation reaction mechanism of the bi-functional catalyst in the hydrocracking process were listed and analyzed. Recent advances in hydrocracking bi-functional catalyst for wax oil hydrocracking have been emphatically introduced. Besides, the influence of active metal components, supports and additives on the hydrocracking process were also discussed. The analysis shows that the loading of active metals, the acid content and pore structure of the carrier have a great influence on the catalytic performance. The key of improving the activity of hydrocracking catalysts is the optimization and reasonable matching between the active sites of hydrogenation metal and the acid sites of cracking. In addition, the integration of composite-multi-model pores and active sites undoubtedly improve the product distribution and product property of wax oil hydrocracking based on the shape selectivity of zeolite. © 2021, Chemical Industry Press Co., Ltd..
