摘要：The hydrodenitrogenation(HDN) performance improvement is the crucial factor but also the difficulty in the development of hydrotreating catalyst for inferior gas oil, while catalyst support preparation and modification technology are the core of obtaining high-performance hydrotreating catalyst for inferior gas oil. To deal with the issue of large pore size distribution of conventional Al2O3, which is not conducive to the diffusion of reactants and the improvement of specific surface area, the preparation methods (sol-gel method, precipitation method, hydrothermal synthesis method) and their advantages and defects of homogeneous mesoporous Al2O3(MA) support were introduced. In order to improve the catalyst hydrodenitrogenation activity, the promoters (phosphorus, boron, fluorine) modification, composite oxides (TiO2-Al2O3, SiO2-Al2O3) modification and composite modification on Al2O3 support in recent years were reviewed. The changes of support acidity and interaction with active phases after modification and their effect on catalyst hydrodenitrogenation performance were analyzed. Future research should focus on the homogeneous mesoporous Al2O3 support and composite modification, with a view to obtain high activity hydrodenitrogenation catalyst for inferior gas oil. ? 2020, Chemical Industry Press Co., Ltd..
