GasificationWikipedia
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 present in
