A review of applied plasma processing of heavy oil and its model compounds

With the growing energy demand and the continuous decline of high-quality crude oil resources, the efficient utilization of unconventional resources such as heavy oil has become increasingly important. This aids in improving the stability and sustainability of energy supply. Plasma technology demonstrates significant potential in heavy oil processing due to its unique non-equilibrium and high-energy-density properties, positioning it as an efficient heavy oil conversion approach. Many scholars have made significant efforts to improve the processing capacity of plasma and the yield of target products. This article reviews the recent research advances in the application of plasma technology for the processing of heavy oil and its model compounds. A systematic overview and comparison of different plasma devices and their experimental results is provided. The effects of different phase feedstocks, additives and catalysts on plasma processing performance were analyzed. Provide a research framework and direction for future research. Finally, factors and key challenges limiting its industrialization process are identified, with outlooks and recommendations for the future. The aim is to provide a reference for research in the field of heavy oil processing and promote the application and development of plasma technology in the energy industry.
