摘　　要：分析焦化粗苯加工工艺利弊,对新出现的粗苯催化氯化精制工艺作描述,包括粗苯预处理、粗苯催化氯化、加碱蒸吹、精馏、废物处理等,该工艺的投入实施,可达到减少投资、流程短、消耗低、产品质量好的效果。Advantage and disadvantage of crude benzene process from coke chemical plant was analyzed. The new rising refining process of crude benzene by catalyzed chlorination, including preprocess of crude benzene, catalyzed chlorination of crude benzene, stripping by adding alkali, distillation and waste full process were introduced. This new process is put into production. The investment of equipment is lowered. The schematic flow process is shorter, consumption of process is Iowerer, the quality of product is better.
