A system and method for coupling co2 conversion to improve high value product yield from catalytic apparatuses
By introducing a CO2 reforming unit into the catalytic cracking unit, CO and H2 are generated through dry reforming reaction, which solves the problems of catalyst coking and greenhouse gas emissions, improves the conversion rate of heavy oil and the yield of high-value products, and forms a highly efficient catalyst closed-loop system.

AI Technical Summary
When processing low-quality heavy oil, catalytic cracking units produce high yields of dry gas and coke, resulting in large greenhouse gas emissions. Existing technologies struggle to achieve efficient conversion of CO2 and CH4 and enhance the production of high-value products.
By introducing a CO2 reforming unit into the catalytic cracking unit, the reformed dry gas and regenerated flue gas are used to carry out a dry reforming reaction with the regenerated catalyst to generate CO and H2. At the same time, the catalyst is reduced and regenerated, forming a closed-loop system, reducing the problem of carbon deposition, and improving the conversion rate of heavy oil and the yield of high-value products.
It enables continuous reaction and regeneration of catalysts, reduces CO2 and CH4 emissions, improves heavy oil conversion rate and yield of high-value products such as gasoline and propylene, reduces coke yield, and the method is simple and easy to implement.
