Dispersed coal was analyzed and rock experiment was conducted on four coalsof medium-low rank in the aspect of coal and rock configuration, which resulted in eightcoal samples mostly of the vitrinoid group or inert group. Then, an adsorption experimentof CO under different temperatures and pressures as well as a diffusion experiment undernormal temperature and pressure were conducted. The research results indicate that formedium-low rank coal, because the pore structure in the inert group is bigger than that inthe vitrinoid group, the influence on CO adsorption-proliferation of the inert group is biggerthan that in the vitrinoid group, and the adsorption quantity of the inert group is more susceptive. The difference of adsorption quantity between the two groups diminish along withthe improvement of coalification degree. The difference of adsorption quantity between thetwo groups shows no obvious change along with the change of temperature.
