Abstract

Abstract:

The conditions of coke formation and conversion of residual oil hydrocracking were studied intensively. Conditions included reaction temperature（410～440 ℃） and partial hygrogen pressure（3.0～7.0 MPa）and time（20～80 min）. The experiment was carried in high pressure autoclave without catalyst. The degree of coke and conversion of residual oil hydrocracking increased as reaction temperature and time and partial hygrogen pressure increased, but partial hydrogen pressure effected the degree of coke slightly. The results show that the optimum condition is: at 430 ℃ and 7.0 MPa when reacting 20 min. 

Key words: Reaction temperature , Partial hygrogen pressure , Reaction time , Coke formation , Conversion

摘要： 使用高压釜反应器，无催化剂条件下，考察了反应温度(410～440℃)、初始氢气压力(3 .0～7 .0 MPa) 及停留时间(20～80 min)对渣油加氢结焦及转化率的影响。当温度、停留时间增加时，渣油转化率与结焦率都增大，而初始氢气压力增加时渣油转化率增大，结焦率变化不大。结果表明，反应温度为430℃、初始氢气压力为7 .0 MPa 和反应时间为20 min是现有渣油加氢工艺的最佳反应条件。
