Gasification is one of the methods of utilization of lignite. Studies on clean coal technologies are carried out on a wide scale in Poland and worldwide. One of the projects was "The Development of Coal Gasification Technology for High Production of Fuels and EnergyпїЅ carried out under the framework of the National Centre for Research and Development. The project was based on the gasification of lignite from the Be?chatпїЅw deposit. For syngas production, a circulating fluidized bed reactor and CO2 as the gasifyi...

The coal gasification process is currently developed as one of clean coal technologies. Gasification is a high-temperature process (above 800 пїЅC) in which the coal reacts with a gasifying agent, e.g. air, oxygen, or water vapor. As a result, under conditions of elevated temperature and pressure, chemical bonds in the molecular structure of coal break up and the mixture of water vapor, oxygen, carbon monoxide, and hydrogen, commonly known as syngas, is produced. The chemical composition of the obtained syngas is ...
