Crusher Coal Gasification

Gasification Wikipedia

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 H 2 and carbon dioxide CO 2 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
