Doubts about the catalytic terminator
Thread Content
What is a suitable terminator to use in a catalytic reaction riser reactor? Is it appropriate to use fractionated acidic water as a terminator? (Mostly, acidic water becomes alkaline – could this have an impact on the acidic sites of the catalyst?) I hope to receive guidance from all the teachers. Thank you!
To increase the production of liquefied gas or gasoline while reducing olefins, it is possible to use stabilized gasoline as a terminator; for schemes aimed at increasing gasoline production, light diesel or water can be used as terminators. Meanwhile, to boost the production of both gasoline and diesel or to achieve the highest yield of light hydrocarbons, acidic water can be used as a terminator
We generally use heavy gasoline; if it is necessary to reprocess light contaminated oil, then we use light contaminated oil
It is not recommended to use acidic water as a quenching agent; nowadays acidic water tends to be alkaline, which can deactivate the catalyst. It is suggested to use crude gasoline or deionized water instead
I have read relevant literature indicating that demineralized water is used as a quenching agent
A teacher said: The alkaline substance in acidic water does not neutralize the acidity of the catalyst! We don’t know either if it’s true or not.
We have used crude gasoline, acidic water, deoxygenated water, and diesel.
Teacher! Is there any difference between using acidic water and deoxygenated water?
