Coal gasification - Wikipedia

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before ...

Gasification - Wikipedia

Gasification is a process that converts organic- or fossil fuel-based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide.This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam.The resulting gas mixture is called syngas (from synthesis gas) or producer gas and is itself a fuel.

Coal is pulverized and fed to the gasifier through two sets of horizontally opposed burners using a transport gas (either syngas or nitrogen). Preheated O2 and steam (as a moderator) are mixed and fed to the injector, where they react with the coal to produce syngas consisting mainly of H2 and CO with only small amount of CO2 and no hydrocarbon liquids or gases.
