Hydrogen production
Thread Content
I had heard before that hydrogen production conversion furnaces have very high temperatures, but the furnaces I see these days are those heated with heat transfer oil; actually, these can only be considered heat exchangers. I wonder if there are any conversion furnaces that truly qualify as such. What is the typical temperature inside such furnaces?
Here, at the outlet of the converter, the furnace temperature is around 760, while it’s generally below 1000 in the furnace.
The temperature of the heat transfer oil here is at most 320; does hydrogen production from methanol require a lower temperature?
The heating furnace for heat transfer oil is around 300°C; this temperature is chosen for the methanol-to-hydrogen process； The process of the converter is used in NH3 cracking and hydrocarbon reforming; NH3 cracking takes place at around 760–800°C, while hydrocarbon reforming occurs at approximately 800–840°C.
Hydrogen production via hydrocarbon steam reforming involves a furnace temperature of around 1000°C.
Well, in that case, this is a different process from our methanol method
