In the practical operation of a tubular reactor, is it beneficial for the reaction to control the inlet temperature, or is it better to control the jacket temperature?

Hello, our current practice is to keep the temperature of the incoming gaseous material higher than that of the jacket. As a result, the reaction at the top of the catalyst is intense; the temperature in the upper part of the bed is about 20°C higher than that of the jacket, while the temperature in the middle and lower parts of the bed is equal to that of the jacket, with little to no reaction occurring there. The composition of the material in the reaction mixture indicates excessive reaction and an increase in side reactions. If we reduce the temperature of the incoming material and increase the temperature of the jacket, could this help bring the reaction to the middle and lower parts of the bed, thereby reducing side reactions, facilitating the main reaction, and increasing the production capacity?
It is possible to control both the inlet temperature and the jacket temperature; the latter is used to control the temperature at the rear of the reactor.
The temperature of the reaction bed is primarily controlled by the temperature at the outlet of the reaction feed furnace; if the reaction feed cannot be changed, it is necessary to reduce the temperature at the outlet of the feed furnace
