How to reduce the catalytic fuel-to-air ratio?
1. One-way conversion. 2. Optimize the operation of the fractionation tower to achieve the highest possible dry point for gasoline, with the diesel-gasoline overlap not exceeding 10°C.
Are there any methods for controlling catalytic reactions?
1】High activity, high oil-to-reagent ratio, improved reaction depth； 2】Raise the diesel cut point and increase the diesel flash point. Reduce the overlap between diesel and gasoline ； 3】Optimize raw material properties ；
New catalysts that can reduce diesel yield are available. We have dual lift pipes; the gasoline lift pipe is now used to feed the hydrogenated diesel back in.
High oil ratio, low reprocessing ratio, high activity, high gasoline dry point, appropriate terminator, high reaction temperature
Is your gasoline still selling well? The market has been weak lately, and it seems that gasoline isn’t selling easily
1. Appropriately increase the reaction depth. 2. Adjust the distillation system and appropriately modify the heat extraction load from the first intermediate stage in order to reduce the mixing of steam and diesel.
The temperature of the catalytic reaction has an impact on gasoline and diesel: at higher reaction temperatures, more gasoline is produced (up to 525 degrees), while at lower temperatures, more diesel is produced.
Increase the amount of freshening agent added to boost catalyst activity, raise the reaction temperature, and increase the dry point of gasoline.
