Abstract
A gas–coal solid solution is shown to be a metastable form of methane molecules in the coal microstructure. Its decomposition on account of molecular repulsion occurs when the pressure in the coal bed is released. It is also established that the gas content of the coal bed consists of the methane formed in the coal bed over its entire geological existence and cannot be estimated by means of the Langmuir formula. A model developed for the decomposition of the gas–coal solid solution yields a mathematical equation describing this process.
期刊介绍:
The journal publishes scientific developments and applications in the field of coal beneficiation and preparation for coking, coking processes, design of coking ovens and equipment, by-product recovery, automation of technological processes, ecology and economics. It also presents indispensable information on the scientific events devoted to thermal rectification, use of smokeless coal as an energy source, and manufacture of different liquid and solid chemical products.
