The Polish power industry is based on coal, both hard coal and brown coal. In the nearest future, for about another 50 to 100 years coal will still be a foundation of Polish and global power industry. Therefore, burning crude oil and natural gas is an unrecoverable waste of these precious resources. Renewable energy sources currently represent...

Please cite as: CHEMIK 2014, 68, 12, 1026–1039

More and more frequently recurring questions regarding the possibility of replacing classical coal mining and combustion for obtaining energy have recently motivated a number of research works. Over last 5 years the intensive research in this area has been also conducted in Poland. However, this paper presents two other cases of gasification: in surface gasification reactors, used successfully...
