Gasification is a thermochemical process that converts any carboncontaining material into a synthesis gas ("syngas") that can be used as a feedstock: to make valueadded biofuels and biochemical, as a fuel for combined cycle power generation, or; as a replacement for fossil fuels including coal, fuel oil and natural gas.

Hydrogen Production Using Coal Gasification The process most likely to be used for turning coal into hydrogen is called gasifi cation. Coal gasifi cation dates back to the mid 19th century when it was used to make "town gas" for local cooking, heating, and lighting—many of the uses that natural gas meets today.

The diversification of coal for its sustainable utilization in producing liquid transportation fuel is inevitable in countries with huge coal reserves. Gasification has been contemplated as one of the most promising thermochemical routes to convert coal into highquality syngas, which can be utilized to produce liquid hydrocarbons through catalytic FischerTropsch (FT) synthesis. Liquid ...

Coal gasification. Coal gasification involves coal reaction with air, oxygen, steam or their mixture to produce a gaseous fuel termed synthesis gas. The principal controlling properties of coal during the gasification process are its reactivity, ash and slag properties, particle size and coal caking and swelling. Coal reactivity

Researchers have investigated the solar coal gasification process on raw materials, reactors, and energy utilization forms. Gregg et al. [12] studied solar coal gasification, using bituminous coal, activated carbon, coke, coal and biomass as raw materials, and estimated that about 60 % of the solar energy entering the reactor was stored.
