Discussion on reaction pressure and hydrogen consumption
Thread Content
It is easy to understand that as the reaction pressure increases, the hydrogen consumption for dissolution also increases. So the question is: as the reaction pressure increases, how does the consumption of chemical hydrogen change? Please provide a detailed analysis
It should be increased; from the perspective of chemical equilibrium, increasing pressure facilitates the forward progression of the reaction, which is beneficial for hydrogenation reactions.
Increase: From the perspective of chemical equilibrium, increasing pressure facilitates the forward progression of the reaction, which is beneficial for hydrogenation reactions； At the same time, the reaction depth should also increase
If the composition of the raw materials remains unchanged and the temperature at the reactor inlet stays constant, increasing the pressure in the reaction system appropriately results, based on experience, in little change in the desulfurization efficiency. However, the denitration reaction and aromatic saturation reaction increase slightly; therefore, I believe that the chemical hydrogen consumption may increase slightly as well.
Not necessarily. Increasing the reaction pressure is equivalent to increasing the reaction depth, and hydrogen consumption will increase at this time. However, when the catalyst reaches the end of its life, its activity decreases, and it is difficult to increase the degree of reaction even by raising the pressure; generally, increasing the temperature is used to enhance the degree of reaction.
With all other conditions unchanged, I believe that simply increasing the pressure will lead to an increase in hydrogen consumption, as higher pressure facilitates the forward progression of the reaction, resulting in more hydrogen being used. . . . . I’m not sure if what I’m saying is correct; I’m a newcomer learning ***.
Theoretically, it definitely increases; in actual production, the effect isn’t very noticeable
