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