An experimental study has been carried out on sorption of carbon monoxide in several samples of hard coal from Polish mines and in active carbon sample as a reference model having well developed pores structure. It has been demonstrated that sorption of carbon monoxide is influenced by both carbon and oxygen content in a given coal sample. Then the same samples of coal have been used for carbon monoxide desorption tests, where it has been demonstrated that this sorption process is irreversible. Desorption and sorption isotherms do not converge, even under low values of relative pressures. The quantity of CO remaining within coal matter is diminishing along with increasing carbon content and with lowering oxygen quantity in coal structure.
