Abstract

The equilibrium composition of the products of the fluidized-bed pressure gasification of brown coal from the Daurskoe deposit in Transbaikalia krai for the production of process gas (in particular, synthesis gas) was calculated with the use of a method of chemical thermodynamics. The gasification was performed at P = 0.1 MPa and the blast coefficient α1 = 0.3–0.35 in the presence of 36 wt % of water vapor in a temperature range of 100–1500°C. It was found that, at a Cl0 pressure of 0.1 MPa, a temperature of 850°C, and the air-steam blast composition of α1 = 0.3 and α0 + 36 wt % H2O, the gasification products of the organic matter of coal (OMC) mainly consisted of CO and H2.
