    Coal is a combustible black or brownish-black ... Coal can be used as a feedstock in the production of a wide range of chemical fertilizers and other chemical ...

  3. Coal gasification - Wikipedia

    en.wikipedia.org/wiki/Coal_gasification

    Most of them use coal as feedstock. [8] As of 2017 large scale expansion of the coal gasification industry was occurring only in China where local governments and energy companies promote the industry to provide jobs and a market for coal. For the most part, the plants are located in remote, coal-rich areas.

  4. Coal gas - Wikipedia

    en.wikipedia.org/wiki/Coal_gas

    Using the coal gas waste as feedstock, researchers developed new processes and synthesized natural organic compounds such as Vitamin C and aspirin. The German economy relied on coal gas during the Second World War as petroleum shortages forced Nazi Germany to develop the Fischer–Tropsch synthesis to produce synthetic fuel for aircraft and tanks.

  5. Coal gasification commercialization - Wikipedia

    en.wikipedia.org/wiki/Coal_gasification...

    Coal gasification is a process whereby a hydrocarbon feedstock (coal) is converted into gaseous components by applying heat under pressure in the presence of steam. Rather than burning, most of the carbon-containing feedstock is broken apart by chemical reactions that produce "syngas."

  6. Raw material - Wikipedia

    en.wikipedia.org/wiki/Raw_material

    Sulfur at harbor in North Vancouver, British Columbia, ready to be loaded onto a ship Latex being collected from a tapped rubber tree. A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products.

  7. Chemical looping reforming and gasification - Wikipedia

    en.wikipedia.org/wiki/Chemical_looping_reforming...

    For coal-based feedstock applications, this system is estimated to reduce the cost for electricity generation by 5-15% as compared to conventional systems. [ 1 ] The selective oxidation based chemical looping processes can be used to produce directly in one step value-added products beyond syngas.

  8. Coal liquefaction - Wikipedia

    en.wikipedia.org/wiki/Coal_liquefaction

    Carbon capture and storage including enhanced oil recovery and developmental CCS methods to offset emissions from both synthesis and utilization of liquid fuels from coal, Coal/biomass/natural gas feedstock blends for coal liquefaction: Utilizing carbon-neutral biomass and hydrogen-rich natural gas as co-feeds in coal liquefaction processes has ...

  9. Gasification - Wikipedia

    en.wikipedia.org/wiki/Gasification

    This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in the reaction. The resulting gas mixture is called syngas (from synthesis gas) or producer gas and is itself a fuel due to the flammability of the H 2 and CO of which the ...
