How catalytic cracking improves octane number
There are many methods; it is recommended to consult Ma Bowen’s \"Technical Q&A on Catalytic Cracking Units\". To briefly mention a few key points, these include reaction temperature, reaction pressure, catalyst-to-oil ratio, catalyst activity and formulation, as well as additives
Increase the reaction temperature, control the blending of raw material components with a certain amount of common slag, and select an appropriate catalyst. A certain amount of light gasoline can also be reprocessed appropriately.
Good raw materials; additionally, octane-boosting additives can be added
Increase the slag content, use high-octane additives, and so on
Increasing slag inclusion to raise the content of naphthenes and aromatics in the feedstock, using additives, high reaction temperatures, and a high oil-to-reagent ratio
