Catalytic Oxycracking of Vacuum Gas Oil

The article presents an in-depth study of catalytic oxycracking of vacuum gas oil, a process that integrates cracking and partial oxidation to convert heavy hydrocarbons into valuable products. It explores the complex thermochemical reactions involved, highlighting the critical parameters that affect the explosion risk and the selection of reaction space geometry and oxidant injection methods. The research identifies key processes such as degradation, dehydrogenation, and oxidative dehydrogenation that occur during the catalytic oxycracking. Detailed kinetic parameters including rate constants, reaction order, and activation energy are determined, offering insights into the formation of hydrocarbon and oxygen-containing compounds. The study also investigates the influence of process parameters like temperature, oxidation degree, contact time, and process time on the conversion degree and product yield. Notably, the presence of oxygen is found to significantly enhance the yield of desired liquid fractions and gaseous products. The article concludes by discussing the potential applications of the resulting fractions, emphasizing the importance of selecting optimal process conditions for efficient conversion and high-quality product yield.
