The characteristics of engineering technologies of first residue hydrotreating processes both in China and abroad and technical status of residue hydrotreating technologies to be engineered are introduced. The technical gap between the engineering technologies of Chinese residue hydrotreating processes and those of overseas residue hydrotreating processes is analyzed, and ways to fully utilize the existing residue hydrotreating units in China are studied. The orientations of engineering technology development of Chinese residue hydrotreating processes are recommended ： （ 1 ） development of engineering technologies for moving-bed residue hy- drotreating process to improve the utilization of resources ; （2） development of engineering technologies for in- tegrated switch-bed （or moving-bed） and fixed-bed residue hydrotreating processes to extend the operating cy- cle of the fixed-bed unit ; （3） development of engineering technologies for large residue hydrotreating units to improve the efficiency of capital investment; （4） development of engineering technologies for integrated moving-bed residue hydrotreating and fixed-bed VGO hydrocracking processes to increase the conversion of heavy oil; （5） development of engineering technologies for int hydrofining processes to produce the blending component egrated residue hydrocracking and fixed-bed gas oil for clean fuel.
