Gassification
Gasification is a thermochemical process that converts carbonaceous materials into a synthesis gas, also known as syngas. This syngas is primarily composed of carbon monoxide (CO) and hydrogen (H2), with smaller amounts of carbon dioxide (CO2), methane (CH4), and nitrogen (N2). The process involves heating the feedstock in a controlled environment with a limited amount of oxygen, steam, or air. Instead of complete combustion, the feedstock undergoes partial oxidation, pyrolysis, and reduction reactions.
The feedstock for gasification can be diverse, including coal, biomass, municipal solid waste, and even plastics.
The syngas generated through gasification is a versatile intermediate. It can be used directly as a fuel
