Methanol production desulfurization process
Thread Content
Is it better to use cobalt-molybdenum or nickel-molybdenum as the catalyst for the hydrogenation reactor in the desulfurization process of methanol production?
If the gas contains oxygen and unsaturated hydrocarbons of C2 and above, use NI-MO hydrodesulfurization catalyst； In other cases, CO-MO catalysts can be used. Under the same circumstances, the cost of the former is higher.
I found a relevant introduction in the forum. I hope it will be helpful to you. Block flow chart of coke oven gas synthesis methanol fine desulfurization process. http://bbs.hcbbs.com/thread-84032-1-1.html
Our factory uses cobalt-molybdenum hydrogenation, which I don’t think is very good.
The side reaction of hydrogenation of cobalt and molybdenum is relatively strong, and it is easy to overheat. Nickel-molybdenum reacts more gently.
