Thermal decomposition of coal and coal-enrichment wastes

Thermal decomposition of coal and coal-enrichment wastes The thermokinetic parameters of the thermal decomposition of coal and its processing wastes (filter cake) used in the preparation of coal–water and organic coal–water fuels are determined experimentally by thermogravimetry in an inert atmosphere. The dependence of the thermokinetic parameters of decomposition on the coal’s metamorphic stage is established; the activation energy of decomposition varies from 39.1 kJ/mol (lignite) to 109.4 kJ/mol (anthracite). There is practically no difference between coal and its processing wastes in the thermokinetic parameters of thermal decomposition. The results provide the starting point for an experimental database that may be used in modeling the ignition and combustion of coal and its derivatives: coal–water and organic coal–water fuels. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

The thermokinetic parameters of the thermal decomposition of coal and its processing wastes (filter cake) used in the preparation of coal–water and organic coal–water fuels are determined experimentally by thermogravimetry in an inert atmosphere. The dependence of the thermokinetic parameters of decomposition on the coal’s metamorphic stage is established; the activation energy of decomposition varies from 39.1 kJ/mol (lignite) to 109.4 kJ/mol (anthracite). There is practically no difference between coal and its processing wastes in the thermokinetic parameters of thermal decomposition. The results provide the starting point for an experimental database that may be used in modeling the ignition and combustion of coal and its derivatives: coal–water and organic coal–water fuels.
