摘　　要：采用不同处理方式对活性炭载体进行处理,对处理后载体进行脱砷剂样品制备。以催化裂化汽油为原料油,注入砷化氢气体,获得含砷原料油。通过液相脱砷评价,考察活性炭载体不同处理方式对脱砷性能的影响。研究表明:8%硝酸处理后水洗至中性的载体制备的脱砷剂脱砷性能最好,平均转化率可达98.42%。The activated carbon carrier was treated by different methods, and the samples of dearsenization agent were prepared.Arsenic-containing feedstock was obtained by injecting hydrogen arsenide gas into FCC gasoline as feedstock. The effects of different treatment methods of activated carbon carrier on the performance of arsenic removal were investigated by evaluating arsenic removal in liquid phase. The results showed that the dearsenization agent prepared by 8% nitric acid treated carrier with water washing to neutral had the best dearsenization performance and the average conversion reached 98.42%.
