Sorption and Desorption of Carbon Monoxide in Several Samples of Polish Hard Coal Authors: J. Cygankiewicz, A. Dudzińska, M. Żyła
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 infl uenced 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. |
