Deformations and phase transitions on the swelling of fossil coals in a carbon dioxide medium

摘要

The swelling of fossil coals in an atmosphere of carbon dioxide was analyzed within the framework of a model of the elastic deformation of a medium with an internal volume under the conditions of sorption. The solutions obtained were adequate to experimental data. The possibility of phase transitions in the sorbate substance caused by changes in the sorption potential, which accompany the swelling of coal, was considered.
