How to adjust operations when catalytic cracking gasoline has a high olefin content?
I think the gasoline cut-off should be raised a bit.
The main control in our plant is the reagent-to-oil ratio; an increase in this ratio results in a decrease in the olefin content. By increasing the reaction temperature, the final boiling point of the crude gasoline can be kept higher, which also allows for better control over the levels of olefins and benzene.
Increase the oil-to-agent ratio, appropriately reduce the reaction temperature, enhance the hydrogen transfer reaction, and achieve stable deep stabilization of gasoline
