Abstract :Coal gasification is a process to produce syngas fuels. Syngas is a mixture mainly consisting  of carbon monoxide insert ignore into journalissuearticles values(CO);, hydrogen insert ignore into journalissuearticles values(H2);, carbon dioxide insert ignore into journalissuearticles values(CO2);, methane insert ignore into journalissuearticles values(CH4); and  water vapor insert ignore into journalissuearticles values(H2O);. Historically, coal was gasified using early technology to produce coal  gas insert ignore into journalissuearticles values(also known as “town gas”);, which is a combustible gas traditionally used for municipal  lighting and heating before the advent of industrial-scale production of natural gas. Natural gas is replaced by synthetic fuels, which are generally produced by gasification  process, due to depletion of fossil fuels including natural gas resources. If synthetic  fuel is produced by an air-blown gasification process, it is called as low calorific value  syngas and may be used mostly in IGCC insert ignore into journalissuearticles values(Integrated Gasification Combined Cycle);. Air  is directly blown over the coal in a gasification reactor resulting in the production of the  syngas that is composed chiefly of high amounts of nitrogen and carbon monoxide as  well as a smaller amount of hydrogen as a combustible gas. Alternatively, coal-derived syngas can also be converted into transportation fuels such  as gasoline and diesel through additional treatment via the Fischer-Tropsch process or  into methanol which itself can be used as transportation fuel or fuel additive, or which  can be converted into gasoline by the methanol to gasoline process.
