Sinopec has been granted an invention patent for “A continuous catalytic cracking regeneration operation simulation and evaluation system and method”. According to data from the Tianyancha app, Sinopec (600028) has obtained a new invention patent, titled “A continuous catalytic cracking regeneration operation simulation and evaluation system and method”; the patent application number is CN202210761511.X, and the date of grant is August 12, 2025. Patent Abstract: This disclosure relates to a continuous catalytic cracking regeneration operation simulation and evaluation system and method. The system includes a feed unit for storing the catalyst to be regenerated and a regenerator (2-1) ； The regenerator includes a housing, a feedstock inlet, heat exchange medium internal components (2–5), a char gas inlet, and a regenerator outlet ； The internal component of the heat exchange medium is formed as a tapered spiral coil, which is wound axially around the regenerator and located inside the housing ； The internal components of the heat exchange medium include the heat exchange medium inlet and the heat exchange medium outlet ； The heat exchange medium inlet and outlet extend to the outside of the regenerator shell via pipelines, so that the heat exchange medium within the internal tubes of these components exchanges heat with the substances inside the regenerator shell only through the tube walls. It enables continuous steady-state operation, has a smaller scale making it suitable for use in small and medium-sized laboratories, and allows for more accurate and convenient simulation and evaluation of the coking effects during catalytic cracking regeneration under different conditions. Since the beginning of this year, Sinopec has obtained 2,087 new patent approvals, a decrease of 42.35% compared to the same period last year. Based on the financial data in the company’s 2024 annual report, the company invested 15.215 billion yuan in research and development in 2024, representing a 8.92% increase compared to the previous year.
