Factors affecting the temperature of the reaction bed
Thread Content
I would like to ask the experienced colleagues: under the same conditions, does the properties of the raw material have a greater impact on the bed temperature, or does the hydrogen partial pressure?
The hydrogen partial pressure is definitely the key factor; when there is insufficient hydrogen, no matter how demanding the properties of the feedstock are, it will not be able to participate more in the reaction.
In general hydrogenation reactions, the pressure is not adjusted; usually, changes in the properties of the feedstock cause changes in the bed temperature
Of course, the properties of the crude oil certainly have a significant impact on temperature fluctuations. Hydrogen partial pressure is required by both the catalyst and the reaction process; to some extent, increasing the hydrogen partial pressure has little effect on the reaction heat!
