Abstract
Results of gasification of low-grade coal and coal wastes in the filtration mode with superadiabatic heating are presented for brown coal, flue ash and cake as examples. Gasification of low-grade coal and coal wastes allows one to obtain combustible gas with the combustion heat 2 to 5 MJ/m3 and ensures high degree of coal combustion. In addition, it is possible to obtain up to 10 mass % liquid hydrocarbons with combustion heat 32 MJ/kg, which are valuable for chemical industry.
