Does desulfurization differ under reaction conditions with the same temperature rise but different temperatures?
Thread Content
Will the desulfurization efficiency differ if the inlet temperatures of different reactors are 280 degrees Celsius or 300 degrees Celsius, with the same temperature rise of 50 degrees Celsius and a constant system pressure? I hope those with practical experience can share their views!
It should be different. The reaction kinetics of each reaction system (oil and catalyst) are different, so their reactions to the same temperature rise also vary.
Yes, what was said upstairs is correct; the effects are different.
The desulfurization reaction is closely influenced by the reaction temperature and hydrogen partial pressure; the higher the reaction temperature and hydrogen partial pressure, the better the desulfurization effect and the greater the degree of desulfurization. Temperature rise is merely a comprehensive reflection of the complex reaction heat within the reaction bed, and it can only provide a brief indication of the effectiveness of the desulfurization reaction.
