1 There are known coal reserves ( Figure 1) on all continents, except Antarctica, which are not evenly distributed, with the highest concentration in the northern hemisphere [ 39, 40 ]. But 90% of the world's coal reserves are concentrated in 10 countries (the USA, Russia, Australia, China, India, Indonesia, Germany, Ukraine, Poland, and Kazakhstan).

25.09.2019What is Coal Gasification? Coal gasification is the process of converting coal into synthesis gas (also called syngas), which is a mixture of hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). The syngas can be used in a variety of applications such as in the production of electricity and making chemical products, such as fertilizers.
