Fluidizedbed gasifiers suspend feedstock particles in an oxygenrich gas so the resulting bed within the gasifier acts as a fluid. These gasifiers employ backmixing, and efficiently mix feed coal particles with coal particles already undergoing gasification. To sustain fluidization, or suspension of coal particles within the gasifier, coal of ...

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. Historically, coal was gasified to produce coal gas, also known as "town gas".

Coal Gasification Process. During gasification, oxygen and steam (water vapour) are blown through the coal while it is still being heated (and in a few cases pressurised as well). "Allothermal" refers to a procedure in which the coal is heated by external heat sources, whereas "autothermal" refers to a process in which the coal is ...

The process involves pumping oxygen and steam through a small borehole into the coal seam to produce a small and controlled combustion. Unlike coalbed methane, therefore, the actual coal is converted from a solid state into gas. The hydrogen, methane, carbon monoxide and CO2 are then siphoned off through a second borehole.
