摘要
The kinetics of gas molecule diffusion is considered in a solid with pores. The results obtained describe the effects of porosity and gas solubility on the gas pressure alteration in surrounding closed volume. Estimations have been made for the case of methane absorption by coal substance. (C) 2000 Elsevier Science Ltd. All rights reserved.
