Generating methane adsorption under relaxation of molecular structure of coal

详细

Transformation of molecular structure of coal under long-term effect of confining pressure due to strain relaxation is estimated numerically. It is found that both under dynamic deformation, as has been determined earlier, and under relaxation of molecular structure of coal, atoms of methyl group and hydrogen remove from aliphatic fringe, join together and form molecules of methane. It is shown that these molecules immediately form sorbing-based connection with coal. Volumes of methane adsorption generated in coal due to strain relaxation of molecular structure of coal are calculated.
