Feasibility of carbon dioxide sequestration in deep indian coals

Srinivasan, Shyam Sundhar (2010) Feasibility of carbon dioxide sequestration in deep indian coals. BTech thesis.



The feasibility of carbon dioxide sequestration in Raniganj formation coals found in and around Durgapur, West Bengal, India has been investigated. Factors like ash, moisture, fixed carbon content etc. have been found to influence the gas sorption capacity of the coal samples. It has been found that seam depth, coal maturity and sorption capacity do not have any established relationship. Samples obtained at 1079 m and 1197m showed CO2 sorption capacity as 10.09 ml/g and 11.8ml/g respectively at temperatures of 30⁰C. Experimental data were verified using several adsorption isotherms such as Langmuir, BET, Dubinin-Astakhov (D-A) and Dubinin-Radushkevich (D-R) and was found to best fit D-A model indicated by minimum error. The absolute adsorbed volumes were also determined from the Gibbs values by taking into consideration the adsorbed gas density.
