摘　　要：乙烯一联合车间加氢装置在独山子天利实业总公司的碳五精制、苯乙烯抽提项目实施过程中进行了配套的工艺改造,加工工艺流程由原设计的全馏分加氢工艺改为C_6~C_8组分的中心馏分加氢,进料性质发生了很大的变化,反应器空速也大幅下降。通过对改造前后一段加氢反应器进料性质、产品及运行参数的对比分析认为:一段加氢反应器催化剂运行周期及使用寿命在加工工艺流程改造后得到延长。During the implementation of the C_5 hydrogenation and styrene extraction project of Dushanzi Tianli Industry General Corporation, process transformation was carried out to the hydrogenation unit in ethylene plant. The originally designed full range distillate hydrogenation process was modified to C_6~ C_8 heart cut hydrogenation process,the properties of feedstock changed a lot,and the space velocity in reactor dropped sharply. By comparing and analyzing the feedstock properties,product and operation parameters of the first-stage hydrogenation reactor before and after transformation,the operation cycle and service life of the catalysts in first-stage hydrogenation reactor were greatly extended.
