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 Energy? 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?chat?w deposit. For syngas production, a circulating fluidized bed reactor and CO2 as the gasifying a...

The publication presents an assessment of the possibility of obtaining char from fly and fluidised ashes from coal combustion. It also presents the methodology of measuring the concentration of char in fly ashes as well as the method developed for separating char grains from fly ash samples. The research conducted has shown that both fly and fluidised ashes contain large quantities of unburnt coal grains, which can be used as a substitute in obtaining artificial graphite through the processes of graphitisation. Th...
