Abstract

The sequestration of CO2 within unmineable coal seams is one of the most attractive options for reducing atmospheric CO2 levels. Thus there is currently considerable interest in the interactions of coal with CO2 for its long-term disposal. This paper reports the analysis of coal / CO2 interactions at pressures of up to 30 bar. The results obtained from differential scanning calorimetry (DSC) show that the interactions of CO2 with coal leads to strongly bound carbon dioxide on coal. It was also found that the temperature of the second order phase transition of coal decreases with increase in CO2 pressure significantly, indicating that high pressure CO2 diffuses through coal matrix, causes significant plasticization effects, and changes the macromolecular structure of the coal.

Desorption characteristics of CO2 from coal were studied by temperature programmed desorption mass spectrometry (TPD-MS). It was found that CO2 binds more strongly to coal and demands more energy to desorb from coal at higher pressures.
