Title: A comparison study of carbon dioxide adsorption on polydimethylsiloxane, silica gel, and Illinois No. 6 coal using in situ infrared spectroscopy

Abstract

Adsorption of supercritical carbon dioxide (CO{sub 2}) on polydimethylsiloxane (PDMS), silica gel (SiO{sub 2}), and Illinois No. 6 coal was compared using in situ attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy at pressures up to 14 MPa and temperatures at 40{sup o}C and 50{sup o}C. Only physical adsorption of CO{sub 2} was recorded for PDMS, SiO{sub 2}, and Illinois no. 6. There was no evidence of the formation of carbonic acid, bicarbonates, carbonates, or any other reaction product between CO{sub 2} and PDMS, SiO{sub 2}, and Illinois No. 6 coal. Carbon dioxide adsorption on PDMS and SiO{sub 2} produced a linear isotherm while a typical Langmuir-like isotherm was observed for Illinois No. 6 coal. Attempts to measure CO{sub 2} induced swelling of the three materials was unsuccessful due to the design of the ATR-FTIR cell. 51 refs., 7 figs., 1 tab.
