Reaction pressure for hydrogen production from natural gas
Thread Content
At what reaction pressure is the highest conversion rate for hydrogen production from natural gas?
The conversion system is around 2.5 MPa!

The pressure in each reactor ranges from 2.2 to 3.0 Mpa
The conversion reaction for hydrogen production from natural gas results in an increase in volume; theoretically, reducing the pressure should facilitate the reaction, but temperature, the water-to-carbon ratio, and catalyst activity all affect the progress of the reaction. When the pressure reaches 2.0 MPa, the conversion rate is basically above 90%
It’s not that strict; it depends on the properties of the conversion catalyst, as well as the outlet temperature and pressure – it can’t be considered in isolation!
Generally, a conversion rate of around 2.2 MPa–2.6 MPa can be achieved; increasing the pressure further does not result in a significant increase in conversion rate, but it does require much more from the equipment.
