Methane diffusion parameters for sized coal particles: a measuring apparatus and some preliminary results. Report of investigations for 1972

  title={Methane diffusion parameters for sized coal particles: a measuring apparatus and some preliminary results. Report of investigations for 1972},
  author={R. Bielicki and J. Perkins and F. Kissell},
A sorption apparatus for measuring the equilibrium sorption isotherm and the rate of diffusion of methane from fine-sized coal was designed and constructed. Preliminary work using Pittsburgh and Pocahontas No. 3 coal shows that the diffusion coefficient varies with pressure and that the fracture spacing in these two coals is substantially different.
