摘　　要：我国是富煤贫油国家,煤焦油的深加工尤为重要。就现有国内几套煤焦油装置不能长周期运行,究其原因是预处理过程中没将不饱和烃及胶质沥青质除掉,导致加氢裂化反应器结焦所致。主要研究在深加工高温煤焦油过程中,预处理用悬浮床反应器替换传统的分馏塔,保证装置长周期运行。China is rich in coal and short of oil, so the deep processing of coal tar is very important. The reason to cause that the existing domestic several sets of coal tar devices cannot realize long term operation was analyzed. The results show that the reason is that the unsaturated hydrocarbon and colloid asphalt are not removed in the process of pretreatment, which causes the hydrocracking reactor coking. In this paper, the pretreatment with suspended-bed reactor instead of the traditional fractionating column was studied to ensure the device long term operation in the deep processing of high temperature coal tar.
