LOW-PRESSURE SORPTION OF CO_2 AND CH_4 ON EX1NITE CONCENTRATES

摘要

The rate of CO_2 and CH_4 sorplion on the exinite maccrals concentrates, isolated from flame and gas-flame coals. No signilicant differences in CH_4 sorplion capacity of both samples were found empirically, despite of various sorplion rates. On the other hand, CO_2 sorplion capacity of gas-llame exinite is considerably lower than that of flame coal exinite, which may be related to the change in geometry of pores during coalificalion and to reduction of pores accessibility for CO_2 molecules.
