Pre combustion process is related to the treatment of synthesis gas (syngas) composed principally of CO and hydrogen [6].Precombustion rate is premised on the production of syngas, removal of CO 2 and combustion of H 2 [7].In some ways it is oxymoron because CO 2 is obviously not normally available for capture prior to combustion, as CO 2 is a product of coal combustion, not a natural precursor.

This process results in the production of a flue gas that is highly concentrated in CO2, thus simplifying the CO2 capture process. An oxygen production plant is necessary. The third way to capture CO2 from a coal power plant is by IGCC with precombustion capture. This method also requires an oxygen production plant.

PDF An Introduction to CO2 Separation and Capture Technologies

Integrated coal gasification combined cycle (IGCC) plants are an example of the hydrogen route. Coal is gasified to form synthesis gas ( syngas) of CO and H 2. The gas then undergoes the watergas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO 2 is then removed, with the hydrogen being sent to a gas turbine combined cycle.
