摘要
采用高压釜作为减黏反应器对印尼油砂油进行减黏改质处理,考察反应温度为380~440℃、反应时间为5~60min条件下的减黏率、结焦率和反应深度。结果表明,在反应温度为420℃、反应时间为30min的条件下,结焦率为0.91%,产品油50℃动力黏度为395mPa·s,减黏率为99.62%。
The properties of Indonesian tar sand oil were analyzed by thermogravimetric analysis. The visbreaking process for upgrading the oil was tested by autoclave at the conditions of 380-440 ℃, N2 pressure of （1＋0.1） MPa,reaction time of 5--60 min,and stirring rate of 200 r/min to investigate the changes of viscosity reduction rate, coking rate,and reaction depth. The results show that at the reaction conditions of 420 ℃ ,30 rain,the coking rate is 0.91% ,the kinetic viscosity of product is 395 mPa s at 50 ℃ and the viscosity reduction rate reaches 99.62%.
