For large stationary power generation, current interest is in integrating a coal gasification process with hightemperature fuel cells (IGFC) to create ultrahighefficiency, lowemissions power generation systems. The first IGFC demonstration plant with CCS may be in Japan in 2021 as a result of the CoolGen project.

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.

Process: Coal gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas. This gas is then used instead of piped natural gas, methane and others for deriving energy. Insitu gasification of coal or Underground Coal Gasification (UCG) is the technique of converting coal into ...

SCGP The Shell coal gasification process (SCGP) can operate on a wide variety of feedstocks. It consists of three principal stages: 1. Gasification (partial oxidation), in which the feedstock is converted to syngas in the presence of oxygen and a moderating agent (steam) in a refractorylined gasification reactor. 2.

Coal Gasification Process. During gasification, oxygen and steam (water vapour) are blown through the coal while it is still being heated (and in a few cases pressurised as well). "Allothermal" refers to a procedure in which the coal is heated by external heat sources, whereas "autothermal" refers to a process in which the coal is ...
