摘　　要：本文介绍了莱托法高温加氢、萃取蒸馏低温加氢和溶剂萃取低温加氢工艺。阐述了加氢原理,列出了产品质量、收率、能耗指标,对3种粗苯加氢工艺进行了比较,认为粗苯精制改造宜采用低温加氢精制工艺。Litol high temperature hydrorefining process, low temperature hydrorefining process with ex- tractive distillation and low temperature hydrorefining process with solvent extraction are described in the paper. The hydrorefing principle is expounded and the product quality, yield and energy consumption.index are listed. Three kinds of the crude benzol hydrorefining processes are compared. It is considered that the low temperature hydrorefining process should be adopted for the crude benzol refining modification projects.
