Abstract

Heavy oil, as an important energy resource, faces many challenges in its extraction and utilization. With the gradual reduction of global crude oil reserves, the extraction and utilization of heavy oil have become particularly important. The catalytic aquathermolysis technology for heavy oil has received widespread attention as an effective method for heavy oil processing. The research shows that this technology can reduce the viscosity of heavy oil and improve oil recovery by hydrolyzing the colloidal asphaltene in heavy oil at high temperature and cracking it into small molecular structure. In the specific reaction process, organic sulfide plays a key role, and the reaction temperature range is 200~350℃. The experimental data showed that the viscosity of heavy oil decreased significantly and the proportion of saturated hydrocarbons and aromatic hydrocarbons increased after adding catalyst. In addition, the paper also introduces a number of research results and the research and development ideas of new catalysts, which provides a reference for the further development of heavy oil catalytic aquathermolysis technology. Research in this field not only helps to solve the problem of heavy oil extraction, but also opens up new avenues for the sustainable utilization of energy resources.
