Hydrodecomposition reactions of non-hydrocarbon compounds such as those containing sulfur, nitrogen, and oxygen; hydrogenation saturation reactions of alkenes and aromatics (mainly polycyclic aromatics); and a small number of ring-opening, chain-scission, and condensation reactions.
In addition to the reactions mentioned above, there is also the hydrogenation of CO to form methane; hydrogen penetrates into the inner wall of the reactor under high temperature and pressure, reacts with carbon, and damages the metal structure. Hydrogen atoms form hydrogen molecules within the wall, leading to hydrogen bulging, while at low temperatures this can cause corrosion by polyoxysulfuric acids.
