<Li> The heat from the production of syngas is used to produce steam from cooling water which is then used for steam turbine electricity production . </Li> <Li> The syngas must go through a pre-combustion separation process to remove CO and other impurities to produce a more purified fuel . Three steps are necessary for the separation of impurities: </Li> <Ol> <Li> Water - gas - shift reaction . The reaction that occurs in a water - gas - shift reactor is CO + H O ⇌ (\ displaystyle \ rightleftharpoons) CO + H . This produces a syngas with a higher composition of hydrogen fuel which is more efficient for burning later in combustion . </Li> <Li> Physical separation process . This can be done through various mechanisms such as absorption, adsorption or membrane separation . </Li> <Li> Drying, compression and storage / shipping . </Li> </Ol> <Li> Water - gas - shift reaction .
