An in-depth investigation of the adsorption and diffusion mechanism hydrogen in low-rank coals is great significance for optimizing technical path geological storage improving efficiency storage. Two kinds coal samples with a low metamorphic degree from Foran Coal Mine Sihe were used as adsorbents, molecular structure determined experimentally, H2 molecules was analyzed atomic level based on numerical simulation. It found that aliphatic carbon mainly links aromatic ring form branched chain exists an ring, side chain, or bridging carbon, lower deterioration coal, longer length alkane structure. The present polybenzene can provide more effective sites enhance by High specific surface area porosity will samples, while presence oxygen-containing functional groups strengthen interaction between microporous H2. These findings theoretical support application
