摘要：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

Abstract: Hydrocracking tests of Canadian oil sand bitumen, Saudi Arabian heavy vacuum residue and model compound 1 -pheny1 dodecane (PhDD) were carried out in a batch autoclave reactor. The reaction conditions were as follows: pressure 5.0 MPa, temperature 410-430℃, reaction time 0-60 min. The heating with a fine inside filament produced small local high temperature zone in the reaction, its effect on the hydrocracking was investigated. Results show that this method accelerates the formation of free radicals, improves the conversion of heavy oil and its model compound, and increases the yield of the middle fraction oil.
Key Words: heavy oil; hydrocracking; free radical
