Hydrogen from coal gasification
WebThe underground coal gasification (UCG) process represents a modern and effective coal mining technology that enables coal energy extraction through thermic decomposition. The coal is transformed into syngas by oxidizers (e.g., air, technical oxygen, or water steam) and is injected into a georeactor. The produced syngas is exhausted on the surface, where it … WebSince 1955 the South African Coal, Oil and Gas Corporation (Sasol) has produced transport fuels and chemicals from coal. The key steps in the process are the gasification of coal to hydrogen and carbon monoxide, followed by the conversion of this gas to hydrocarbons by the Fischer Tropsch (Ff) process.
