采用间歇式高压釜反应器研究了加拿大油砂沥青和沙特重质减压渣油及其模型化合物十二烷基苯的加氢裂化反应,实验条件为5 0MPa、410～430℃、0～60min。以微小电热丝在反应器中很小的区域制造了局部高温,考察了其对加氢裂化的影响。结果表明,该方法促进了反应物中自由基的形成,提高了重质油及其模型化合物的转化率和中间馏分油的收率。 The hydrocracking reaction of Canadian oil sands bitumen and Saudi heavy crude oil and its model compound dodecylbenzene was studied with a batch autoclave reactor. The experimental conditions were 50 MPa, 410 ~ 430 ℃, 0 ~ 60 min . The local heating was made in a very small area of ​​the reactor by the tiny electric heating wire, and its influence on hydrocracking was investigated. The results showed that this method promoted the formation of free radicals in the reactants and improved the conversion of heavy oil and its model compounds and the yield of middle distillate.
