Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam pres… WebHow gasification works. A general gasification process converts feedstocks into dirty synthesis gas (syngas) The base of the process is a reaction which takes place when feedstock is ‘gasified’ through high temperatures over 700 degrees in the presence of a limited quantity of oxygen.
