Diesel hydrogenation: refining reactor and reforming reactor?
Thread Content
Do the catalysts in your two reactors are the same?
They’re different; one is refined, the other is modified
There is a clear difference; the modified catalyst requires higher operating conditions than the refined one
Of course it’s different; refining generally involves the saturation of olefins, as well as the removal of sulfur, nitrogen, and oxygen, whereas modification entails cracking or isomerization
They’re definitely different; the refined reactor is equipped with protectants and refined catalysts, while the reforming reactor contains reforming catalysts, and some of them also have post-refining agents.
For such easily distinguishable type of reactors, in the reforming process, what is used inside the reforming reactor is generally a reforming agent; whereas in the cracking process, the substance used in the cracking reactor is usually a cracking agent. The final bed layer in the last reactor at the back usually involves post-refining.
