Gasification is a thermal conversion process, where carbonaceous material is converted into gaseous products under the influence of temperature and gasifying medium. In general gasification is carried out in the temperature range of 600°C–1000°C. The commonly employed gasifying agents are steam, air, CO2, and H 2.
