Step 1: CH4+H2O→3H2+CO -Q
By this reaction, a lot of heat will be released and we use an economizer to collect the heat.
Next, the syngas enters the shifter and the carbon monoxide will be changed into carbon dioxide.
Step 2: CO+H2O→H2+CO2 +Q
In the end, after the purification of the PSA system, high purity product hydrogen will be collected in the tank.
