WitrynaThe naphtha hydro treating unit uses a cobalt-molybdenum catalyst to remove sulfur by converting it to hydrogen sulfide that is removed along with unreacted hydrogen. Reactor conditions for a naphtha hydrotreater unit are around 400-500˚F (205-260˚C) with a pressure of 350-650 psi (25-45 bar). WitrynaThe catalytic cracking of naphtha involves coupling of the protolytic, dehydrogenation, and hydrogen transfer cracking pathways. To clarify the reactivity and the effect of the coexistence of cracking pathways, the effects of thermodynamic factors on the equilibrium yields of naphtha systems were investigated.
