    Abstract

    In recent years, attention has been drawn towards decreasing the effusion of anthropogenic carbon dioxide (CO2). CO2 sequestration is one approach used to reduce its concentration in the atmosphere. This is often the case in deep and inaccessible coal seams where underground storage techniques i.e., flue gas and CO2 injection under feeds of subcritical and supercritical settings are required. In a bid to reducing carbon footprints, subcritical CO2 affinity of two sample coal types (sample A-Anthracite and sample B- bituminous) in South Africa was evaluated from adsorbates of flue gas and pure CO2. Volumetric approach using 35°C and 5MPa was used to measure the attraction/adsorption isotherms of the flue gas and pure CO2 respectively. Measurements were carried out on 5g samples all passing the 2.36mm American standard sieve size while the flue gas was simulated from industrial coal fired plant having CO2 = 96.2%, 02 = 1.5% and N2 = 2.3% in a high pressure CO2 volumetric adsorption apparatus. From the generated data, regression models for attraction isotherm were used to resolve the fitness of coal as CO2 adsorbent. Thus from the study, it was realized that the coal attraction of CO2 was not notably altered on introduction of other gases. However, sample-A showed a higher adsorption capacity over sample-B, as has been recorded from similar studies. The data herein could therefore, add to the basis for assessing flue gas and pure CO2 sequestration on South African coal.
