Sorption enhanced water gas shift (SEWGS) is a technology that combines a pre-combustion carbon capture process with the water gas shift reaction (WGS) in order to produce a hydrogen rich stream from the syngas fed to the SEWGS reactor.[1]
The water gas shift reaction converts the carbon monoxide into carbon dioxide, according to the following chemical reaction:
- CO + H2O ⇌ CO2 + H2
While carbon dioxide is captured and removed through an adsorption process.[1]
The in-situ CO2 adsorption and removal shifts the water gas shift reaction to the right-hand side, thereby completely converting the CO and maximizing the production of high pressure hydrogen.[1]
Since the beginning of the second decade of the 21st century this technology has started gaining attention, as it shows advantages over carbon capture conventional technologies and because hydrogen is considered the energy carrier of the future.[2][3]
