    • Disclosed is a combined process for hydrotreating and catalytic cracking of residue, wherein the residue, catalytic cracking heavy cycle oil with acidic solid impurity being removed, optional distillate oil and adistillate of catalytic cracking slurry oil from which the acidic solid impurity is removed are fed into residue hydrotreating unit, the hydrogenated residue obtained and optional vacuum gas oil are fed into catalytic cracking unit to obtain various products; the catalytic cracking heavy cycle oil from which the acidic solid impurity is removed is circulated to the residue hydrotreating unit; the catalytic cracking slurry oil is separated by distilling, the distillate of the catalytic cracking slurry oil after removing off the acidic solid impurity is circulated to the residue hydrotreating unit. This process makes the residue hydrotreating and catalytic cracking being combined together more effectively such that it is not only able to improve product quality of the residue hydrotreating, elongate operation cycle of the residue hydrotreating unit, but also increases the yield of the hydrogenated diesel oil and catalytic cracking light oil, and decreases coking quantity of the catalytic cracking.
    • 公开了一种用于残余物加氢处理和催化裂化的组合方法,其中除去残留物,除去酸性固体杂质的催化裂解重质循环油,任选的馏出油和除去酸性固体杂质的催化裂化浆料油馏出物 进入残渣加氢处理装置,将得到的氢化残渣和任选的减压瓦斯油加入催化裂化装置中得到各种产物; 去除酸性固体杂质的催化裂解重质循环油循环至残渣加氢处理装置; 通过蒸馏分离催化裂化浆料油,除去酸性固体杂质后的催化裂化浆料油的馏出物循环至残渣加氢处理装置。 该方法使残渣加氢处理和催化裂化更有效地结合在一起,使得不仅能够提高残余物加氢处理装置的残余物加氢处理,延长操作循环的产品质量,而且还提高氢化柴油的产率, 催化裂解轻油,降低催化裂化的焦化量。
