The challenges facing the refining industry today mainly include the following aspects: * In terms of resources, the number of conventional** is becoming heavier and worse, and the number of non-conventional** is gradually increasing; The demand for transportation fuels (light oil products) continues to grow, while the demand for heavy fuel oil is gradually decreasing; The quality of the products is constantly improved and the production process is cleaner. This forces refining and chemical enterprises to research and develop technologies for the deep and efficient conversion of inferior heavy oil to continuously improve the yield of light oil and the utilization rate of resources. In recent years, the use of this technology to process residue has become a hot spot and focus of the oil refining industry.
Through in-depth research on the chemical engineering of high-efficiency conversion reaction of heavy oil, CNOOC Limited has developed a new high-efficiency homogeneous oil-soluble catalyst and a new cyclone reactor. Using Huizhou Petrochemical vacuum residue as raw material, the cumulative operation has reached 300h, the conversion rate has reached more than 95%, and the total coking rate is controlled at 0Within 8%, there was no obvious coking in the reactor.
Whether it is the current situation of China National Offshore Oil Corporation (CNOOC) or the actual situation in China, it is very urgent and important to improve the resource utilization rate of heavy oil and the yield of light oil, and slurry bed hydrogenation technology, as the best technology to achieve this goal, requires us to emancipate our minds, carry out relevant work from the aspects of residue molecular characterization, catalyst research and development, conversion mechanism and engineering design, strengthen cooperative relations with domestic and foreign scientific research institutes, and collaborate in innovation. Strive to keep pace with the world in slurry bed hydrocracking technology.
