摘要： 以中海油惠州炼化提供的减压渣油为研究对象,在自主研发的渣油悬浮床加氢装置中进行实验,考察了反应温度、氢分压、催化剂质量分数以及空速对转化率、产物各馏分收率的影响。结果表明,在反应温度460℃、氢分压14MPa、氢油体积比1000∶1、催化剂质量分数300μg/g、空速1.0h-1的最优反应条件下,渣油转化率为 90.50%,生焦率为5.01%。同时分析了渣油悬浮床加氢反应的反应机理与抑焦机理,可为渣油悬浮床加氢裂化技术的工业化提供了理论指导和技术支持。

Abstract: The slurry bed hydrogenation was studied using vacuum residue from CNOOC Huizhou Refining & Chemical as raw material. The effects of reaction temperature, hydrogen partial pressure, catalyst mass fraction and airspeed on the conversion rate and the yield of each product were investigated in slurry bed hydrocracking reactor of independent research and development. The results showed that under the optimal reaction conditions of reaction temperature 460 ℃, hydrogen partial pressure 14 MPa, hydrogen oil volume ratio 1 000∶1, catalyst mass fraction 300 μg/g and space velocity 1.0 h-1, the residue conversion rate was 90.50%, The coke rate was 5.01%. At the same time, the reaction mechanism and the coking mechanism of the hydrogenation reaction of the suspended sediment were analyzed, which provided theoretical guidance and technical support for the industrialization of the hydrocracking technology.
