The Model of Chemical Processes of Coal Pyrolysis Stimulated with Laser Pulse

The model of coal particles' pulsed pyrolysis stimulated by Q-switched laser impact was suggested. It is based on the quasipolymeric concept of the coal organic mass with detailed reactions of its decomposition, volatiles' formation, and carbonized matter growth. The dependencies of the main products' yields on the energy density of the laser pulse were calculated in the case of subbitumenous coal. The endothermic reactions of the organic mass of coal decomposition lead to the sublinear dependence of the maximum temperature of the particle on the energy density. Hydrogen and water dominate in the volatile products.
