Multiple sources of carbon can be used for CO 2 gasification. Coal from varying ranks has been used to study CO 2 gasification, it has been reported that with the increase of coal rank the gasification reactivity decreases [112]. This is caused by the relation between a highly organized carbon structure and a low gasification reactivity [82 ...

Coal Gasification is the process of converting coal into synthetic gas (syngas) which is a mixture of hydrogen (H2), Carbon Monoxide (CO), and Carbon dioxide (CO2). It is an in situ process in which oxygen is injected into the seam along with water and ignited at a high temperature, which causes the coal to partially oxidize into hydrogen ...

As a result, typically an extra step must be taken to reform these hydrocarbons with a catalyst to yield a clean syngas mixture of hydrogen, carbon monoxide, and carbon dioxide. Then, just as in the gasification process for hydrogen production, a shift reaction step (with steam) converts the carbon monoxide to carbon dioxide.
Coal gasification technology is an effective means to achieve clean and efficient utilization of coal. Coal gasification slag is generated in the process of coal gasification owing to the existence of minerals in the coal, particularly the incomplete reaction of the organic carbon elements in the coal.
