Abstract
The present disclosure relates to a natural gas reforming system capable of reducing, by using a co-electrolysis device, the emission amount of carbon dioxide produced by reforming natural gas, of supplying heat to a reformer through syngas produced by the co-electrolysis, and of producing additional hydrogen, and a process thereof.
Claims15
A natural gas reforming process comprising:
- a combustion step of burning fuel and generating combustion gas;
- a reforming step of being supplied with heat of the combustion gas and converting natural gas into reformed gas which comprises hydrogen and carbon monoxide, through a steam reforming reaction;
- a steam generation step of generating steam by heat-exchanging with the combustion gas;
- a water gas shift reaction step of converting the carbon monoxide and steam of the reformed gas into hydrogen and carbon dioxide through a water gas shift reaction;
- a hydrogen separation step of separating the hydrogen from the gas supplied from the water gas shift reaction step;
- a carbon dioxide separation step of separating the carbon dioxide from the gas which is supplied in the hydrogen separation step and from which the hydrogen has been separated;
- and
- a co-electrolytic reaction step of being supplied with the steam and the carbon dioxide separated in the carbon dioxide separation step and producing oxygen and syngas comprising hydrogen and carbon monoxide, through a co-electrolytic reaction.
