Questions regarding the reactor catalyst and feedstock
Thread Content
I’d like to ask for advice here. Does reducing the feed rate to the reactor mean reducing the space velocity? Conversely, if I want to reduce the space velocity, I need to reduce the feed rate as well. Is this the one to go in? What is the impact of improving hydrogen purity on denitration?
The space velocity is the flow rate of the feed oil divided by the volume of the catalyst; since the volume of the catalyst remains constant, the flow rate of the feed oil is directly proportional to the space velocity. The greater the processing capacity, the higher the space velocity. Increasing hydrogen purity is equivalent to increasing the hydrogen partial pressure, which facilitates the progress of hydrogenation reactions; therefore, it is beneficial for nitrogen removal.
The space velocity actually reflects the residence time of the material within the catalyst
