中文摘要：

这篇论文在过热的蒸气论述常规重油的新 aquathermolysis 研究。一个新高温度压热器被设计，在体积和压力能被调整的地方。Aquathermolysis 在不同反应时间和温度下面在二件不同的常规重油样品上被学习。试验性的结果证明 aquathermolysis 确实为常规重油发生。作为反应时间增加，油粘性减少。然而，反应将在时间的某个时期以后到达平衡并且易于对敏感更进一步反应时间再。分析证明当树脂和沥青质减少时，浸透的烃和 H/C 比率在反应以后增加。aquathermolysis 的主要机制包括 hydrogenization，树脂和沥青质的脱硫反应，等等。

英文摘要：

This paper presents a new aquathermolysis study of conventional heavy oil in superheated steam. A new high temperature autoclave was designed, where volume and pressure could be adjusted. Aquathermolysis was studied on two different conventional heavy oil samples under different reaction times and temperatures. Experimental results show that aquathermolysis does take place for conventional heavy oil. As reaction time increases, the oil viscosity reduces. However, the reaction will reach equilibrium after a certain period of time and won＇t be sensitive to any further reaction time any more. Analysis shows that, while resin and asphaltenes decrease, saturated hydrocarbons and the H/C ratio increase after reaction. The main mechanism of aquathermolysis includes hydrogenization, desulfuration reaction of resin and asphaltenes, etc.
