What should be the inlet temperature control in a variable reactor for hydrogen production?
Thread Content
Is the inlet temperature of the reformer higher in hydrogen production nowadays? How much is it best to control?
We control the inlet temperature of Section 1 of the intermediate reactor at 320°C to 360°C. It can be adjusted based on the catalyst properties provided by the catalyst supplier, the design conditions, and the gas analysis from the outlet of the medium-pressure reactor.

Reactions that take place within the range of 300–460 degrees are generally referred to as medium-temperature reactions. This means that the lowest temperature at the inlet can be 300 degrees, while the highest temperature at the outlet should not exceed 460 degrees. As for the exact value of the inlet temperature, it can be adjusted accordingly based on the required CO content in the medium-temperature gas; actually, the range of adjustment is quite small, as the temperature at the outlet of the conversion furnace sets a limit. I don’t think there is such a thing as an optimal control temperature; all controls can be adjusted as needed.
For the shift reaction, since it is an exothermic reaction, a low temperature is favorable for the conversion； For applications that require the waste boiler to produce more steam, the intermediate pressure inlet temperature can also be lowered slightly. In some heat exchange processes after medium transformation, the heat obtained from this transformation is needed to raise the temperature of the raw materials; therefore, it is not possible to keep the temperature low. Therefore, when determining the temperature change, in addition to considering the conversion rate, heat balance also needs to be taken into account.
