Gasoline hydrogenation
Thread Content
At which stage does the denitration reaction take place in the gasoline hydrogenation reactor? ? Which reaction is less difficult, the desulfurization reaction or the denitrification reaction?
Gasoline hydrogenation only removes sulfur; nitrogen removal involves only a few side reactions, which mostly occur at the locations where the temperature is high at the end of the reaction process. Desulfurization is definitely easier to react than denitrification.
The activation energy required for hydrodenitration is higher than that for hydrodesulfurization. For diesel fractions, 300°C is generally sufficient for hydrodesulfurization, while hydrodenitration typically requires temperatures of over 320°C.
The reaction temperature and pressure for gasoline hydrogenation are relatively low; the hydrogenation reactions mainly involve hydrodesulfurization and olefin saturation, with little hydrodenitration occurring
