Where do the elements removed in the hydrogenation reaction go?

Where does all the sulfur, nitrogen, and oxygen removed in the reactor go? Attached to the catalyst surface or eliminated by the reaction
Mutter to yourself the definition of hydrorefining~~~ With that, you’ll have solved most of this problem~~~
Did sulfur go with the hydrogen? What about nitrogen and oxygen?
Was it converted through catalytic reaction, or remains in the oil?
Most of it is hydrogen sulfide. Ammonium salts & water
I suggest you first write down the hydrogenation reaction equation, and then you’ll know what to do
What is the purpose of stripping and distillation after your reaction?
A reactor typically has two beds: the upper bed is used primarily to convert unsaturated hydrocarbons into saturated ones, while the lower bed serves to remove impurities such as O, N, S, and Cl; these impurities are then separated through a stripping tower located downstream
Hydrorefining refers to the process of converting harmful impurities such as sulfur, oxygen, and nitrogen in oils into corresponding hydrogen sulfide, water, and ammonia under hydrogen pressure and in the presence of a catalyst, thereby removing these impurities. It also involves the hydrogenation of olefins and dienes to saturate them, as well as the partial hydrogenation of aromatics, in order to improve the quality of the oil. Sometimes, hydrorefining refers to the refining and modification of light oils, while hydrotreating refers to the refining and desulfurization of heavy oils. :victory:
