Thermodynamic Analysis of Synthesis Gas Production by Brown Coal Gasification

详细

To obtain synthesis gas of the required composition, a thermodynamic study of the process of Kansk–Achinsk brown coal gasification with various oxidants has been carried out, and the equilibrium composition of gasification has been calculated. It has been shown that under the process conditions of an air/coal ratio of α = 0.3, a steam flow rate of 2 mol H₂O/(100 g OMC), a temperature of T = 1078.15 K, and a pressure of P = 0.1 MPa, the equilibrium number of moles of the useful gases H₂ and CO are 3.99 and 4.86 mol, respectively, and the CO + H₂ gas volume is V = 0.37 (STP)m³/(100 g OMC).
