Gasifying agent

Air ,steam Coal gasification is the process of producing coal gas, a type of syngas–a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O)–from coal and water. Coal gas, which is a combustible gas, was traditionally used as a source of energy for municipal lighting and heat before the advent of industrial-scale production of natural gas, while the hydrogen obtained from gasification can be used for various purposes such as making ammonia, powering a hydrogen economy, or upgrading fossil fuels
