· Coal gasification (syngas) is a process of converting coal into a flammable gas (used in the early years of industrialization before production of natural gas came into widespread use) or via the Fisher-Tropsch Process into liquid fuel for transportation purposes (Nazi Germany used this process extensively during WWII).
2020-2-25 · Coal combustion is the largest source of anthropogenic mercury emissions globally, accounting for about half of such emissions, with emissions highest and growing in China and India (156, 164). Flue gas emission control technology can reduce mercury emissions, but this technology is uncommon in low- and middle-income countries ( 172 ).
Underground coal gasification (UCG) is a non-conventional method of extracting gas from coal. The primary advantage of UCG is that it recovers gas from uneconomical or unminable coal, potentially increasing the value of the world''s coal reserves by an estimated 70%; for this reason, UCG has been implemented at sites around the world.
