Abstract—The quantitative composition of the products of the gasification (at P = 0.1 MPa and an air excess
ratio of 0.3 in a temperature range of 114–1534C) of brown coal from the Nazarovskoe deposit of the Kansk-
Achinsk Basin was calculated using a chemical thermodynamics program [1], the database of which contains
the thermodynamic constants of more than 2000 inorganic compounds. The calculation covered the compounds
of both trace elements (V, U, Se, Sr, Ag, and Au) and ash-forming elements (Al, Si, Fe, Ca, Mg, K, Na, and S).
