May 15, 2014 Coal gasification, the technology for high-efficient utilization of coal, has been widely used in China. However, it suffers from high CO 2 emissions problem due to the carbon-rich character of coal. To reduce CO 2 emissions, different CO 2 capture technologies are developed and integrated into the coal gasification based processes. However, involving CO 2 capture would result in energetic
5.2.5 Gasifiers and Impact of Coal Rank and Coal
Feedstock coal rank usually has little effect on the environmental impact of a gasification system. Sulfur,for example, can vary from 0.5 to 8 percent in coal, and while different technologies may be needed to handle the entire range, the resulting emissions would be quite similar and more based on environmental regulations.

Coal gasification
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
