Abstract
The kinetic and thermodynamic parameters (the equilibrium degree of reaction, the rates of forward and reverse reactions, the equilibrium constant, the activation energies of forward and reverse reactions, the Gibbs free energy, and the heat effect and entropy of the process) of the hydrogenation of coal from the Mamytskoe deposit of (Republic Kazakhstan) at 380–440°C were calculated with the use of equilibrium kinetic analysis (EKA). It was established that the rate of forward reaction increased whereas the rate of reverse reaction decreased with temperature. The application of the kinetic–thermodynamic model obtained to the hydrogenation of coal from the Mamytskoe deposit facilitated the understanding of the chemical conversion of the organic matter of coal.
