We have an Axens CCR unit with 4 reactors and I would like to know whether we can maintain different temperature in each reactor? If the answer YES, what are the effect on RON and catalyst? Please share your experience.

It depends on your processing objectives. For example, since most of the hydrocracking occurs in the last reactor, an elevated inlet temperature there will increase octane at the expense of liquid yield. Some refiners who operate in the gasoline mode use a U shaped inlet profile. Some who are maximizing aromatics production do not.
Data from Axens’ pilot plant runs can be used to optimize the inlet profile according to your needs. For, example, if you are short on hydrogen, octane, or yield.
