| 摘 要： | 在研究重金属镍、钒对烃类裂化催化剂中毒机理的基础上，通过具有一剂多能和协同作用元素间的复配和优化，并考虑工业应用的可行性和成本，研制了无毒、高效和稳定性好的DFP抗钒、抗镍双功能水溶性钝化剂，在乌鲁木齐石化公司1.2 Mt/a的重油催化裂化装置(RFCCU)进行了工业应用试验。结果表明，当原料油中掺质量分数为39％～42％的减压渣油，平衡剂上钒质量分数高达7.5×10－9～9×10－9，镍质量分数为5×10－9～6×10－9条件下，使用DFP钝化剂与国产钝化剂MP相比，轻质油收率提高0.45%,焦炭产率下降16％～20%,氢气产率下降25％～30%，平衡剂活性指数提高4～5个单位，使用方便，有显著的经济效益和社会效益。

| Abstract: | DFP, a newly developed vanadium and nickel passivator featured by non-toxicity, high efficiency and stability, was tested on a industrial RFCC unit. Test results showed that, with 39%-42% (wt) residue in the feedstock and 7500-9000 ppm vanadium and 5000-6000 ppm nickel in the equilibi-um catalyst, light oil yield and activity were increased by 0.45% and 4%-5% respectively, and coke yiel dand hydrogen yield were reduced by 16%-20% (wt) and 25%-30% (wt), respectively, compared with MP, a typical passivator in domestic market. |
