Gasification is a process in which the fuel is heated in the presence of some oxygen or steam into a temperature where the solid or liquid fuel components are broken to gaseous components, see Figure 6. These components include H 2, CO, CH 4 and other hydrocarbons. Some tars may still remain after the initial gasification process, and also N 2, H

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

There are 3 kinds of thermal processes known so far, namely combustion, gasification and pyrolysis. Differences of the three could be reviewed by the presence of air / oxygen, temperature and the resulting product. Pyrolysis is a thermal process that oxygen / air is very limited or even 0 percent or vacuum.

Nov 20, 2017· Gasification may take place with either air or pure oxygen input. (Anthony, et al., 2014) Air gasification yields gas with high N 2 content commonly known as producer gas; gas from oxygen gasification is known as synthetic gas or syngas. Steam may also be introduced into the gasification environment as an oxygen carrier.
