Thermodynamic simulation of the composition of mineral compounds upon the gasification of brown coal from the Kansk-Achinsk Basin

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 114–1534°C) 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).
