Carbon dioxide adsorption isotherm study on various cap rocks in a batch reactor for CO2 sequestration processes
Source abstract
Abstract
Abstract The purpose of this article is to present the effects of CO 2 adsorption on sealing rocks in the context of carbon dioxide sequestration. Various samples (clay, sandstone and evaporates) have been experimentally reacted in a low-salinity water with supercritical CO 2 in situ reservoir conditions ( P = 80 bars and T = 80 °C). Adsorbents were characterized thoroughly via X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and nitrogen adsorption. Adsorption isotherms were measured at T = 298 K, 353 K. Experimental data of CO 2 adsorption isotherms were modeled using Langmuir models. Based on the correlation coefficient, the isotherm model is well suited to the experimental data of CO 2 adsorption isotherms. Limiting heat of adsorption at zero and isosteric heat as a function of the surface coverage were evaluated using Clausius–Clapeyron equations. These thermodynamic properties indicate that the uptaken CO 2 occurred mainly by physi-adsorption phenomenon. The adsorption isotherms data and the thermodynamic parameters estimated in the present study are useful for the designing of the adsorption based gas storage systems.
