Shell Coal Gasification Process - an overview ...

The Shell coal gasification process (SCGP) uses an up flow, entrained flow gasifier operating on a dry feed at slagging temperatures (Fig. 8.5).The up flow arrangement allows separation of syngas and slag largely within the reactor itself. Typically, there are four side mounted burners located in the lower part of the reactor. The vessel containment uses a membrane wall, which has a ...

What is coal gasification? | HowStuffWorks

The U.S. Department of Energy explains that coal gasification is a thermo-chemical process in which the gasifier's heat and pressure break down coal into its chemical constituents. The resulting "syngas" is comprised primarily of carbon monoxide and hydrogen, and occasionally other gaseous compounds.

Coal Gasification Process - Assignment Point

Coal is best known for its role supplying electricity throughout the world—nearly 200 country's electricity comes from coal. Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), natural gas (CH4), and water vapor (H2O)—from coal and water, air and/or oxygen.
