Environmental benefits of underground coal gasification are evaluated. The results showed that through underground coal gasification,gangue discharge is eliminated, sulfur emission is reduced, and the amount of ash, mercury, and tar discharge are decreased.

What are the advantages of Co-coal gasification?
Coal gasification methods also sought to remove impurities like sulfur and mercury from coal to make it a more efficient source of energy. These methods of using energy more efficiently lead to recycling the ash from coal gasification into a concrete aggregate rather than sending it to a landfill.
What is coal gasification and how does it work?
The coal gasification process would produce hydrogen, ammonia, methanol and hydrocarbons, and they were also used with steam to create synthetic natural gas (SNG). These reactions would produce synthetic gases generally composed of carbon monoxide (CO) and hydrogen gas (H2). By the 1930s, underground coal gasification (UCG) also took root.
Does gasification reduce pollution?
Gasification-based processes for power production characteristically result in much lower emissions of pollutants compared to conventional coal combustion.
How can I learn about the disadvantages and advantages of coal?
You can learn about the disadvantages and advantages of coal by learning about how coal gasification emerged throughout history. Understanding the coal gasification process as one that’s multidimensional and composed of positives and negatives can let you make better decisions about using coal.
