摘　　要：在DZ 1催化剂的基础上,开发了高活性的齿球型DZCⅡ 1催化剂,该催化剂比DZ 1催化剂反应温度低10℃。在反应压力4 0MPa、体积空速2 0～4 5h-1、氢油体积比300∶1和反应温度≥230℃的条件下,生成油的溴价≤0 5g Br2/100g,二烯价为0,达到了芳烃抽提的指标要求。DZCⅡ-1 catalyst was developed by Research Institute of PetroChina Daqing Petrochemical Corp. for secondary hydrogenation of pyrolysis gasoline upon basis of its DZ1 catalyst. The catalyst, with a shape of dentiform sphere, can produce high quality pyrolysis gasoline with bromine value of ≤ 05 gBr2/100g and iodine value of 0, which satisfies the demand of aromatics extraction unit. Operation condition: 40MPa (hydrogen pressure), ≥230 ℃, LHSV 20-45 h-1 , hydrogen/oil 300:1(vol). 
