WebOf all gasification processes, coal gasification has gained much interest from last three decades. Coal can be gasified by reacting it with mixture of air and steam at various temperature and pressure conditions. Biomass gasification is also gaining attention in recent times as it represents an attractive sustainable energy alternative. In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapour (H2O)—from coal and water, air and/or oxygen.
