| Abstract: | 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-Br2/100g 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). |
