Abstract:Porosity in coal plays an important role in determining sorption capacity and diffusion behaviour of a given gas. Total porosity and pore size distribution are known to change with rank and composition. Total porosity declines whereas micropore volume increases with rank. On the other hand, the variability in composition among coals makes it difficult to track the changes due to the influence of various plant precursors. This study examines pore structure changes from the original plant structure represented b… Show more
