Abstract: Catalytic cracking technology has become one of the core technologies in the transformation and development of refineries as the fuel-based refineries accelerate the transformation to integration of refining and chemical. A series of catalytic cracking technologies with product structure diversity developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd. were introduced, and the technological innovation, technological characteristics, application scenarios and industrial practice results were emphatically analyzed. Catalytic cracking technology realized the innovation chain from applied basic research to reactor technology development and then to transformation of production. A series of catalytic cracking technologies for enhancing petrochemicals production have become one of the most important technical support and solutions for refining enterprises to achieve the goal of “oil to chemicals”, which can realize the efficient utilization of refinery light distillate oil, heavy distillate oil and even crude oil.
