“…However, the adsorption data of CO 2 on other adsorbents, such as natural zeolites, β-zeolite, were not available in their paper. Li and Tezel (2007) also compared the dimensional Henry's Law adsorption equilibrium constants of CO 2 on β-zeolite and NaY zeolite and came to a similar conclusion that the NaY zeolite has better CO 2 adsorption capacity. Siriwardane et al (2003) and Jaramillo and Chandross (2004) studied CO 2 adsorption behavior on natural zeolites and zeolite 4A, but it was found that the amounts of CO 2 adsorption on natural zeolite and zeolite 4A were lower than that on the NaY zeolite reported by Harlick and Tezel (2004).…”

“…Regarding CO 2 adsorption and separation, it is of great significance to obtain high CO 2 adsorption capacity because the CO 2 adsorption behavior greatly influences the CO 2 separation and desorption processes on NaY particle and membrane. A number of efforts have been made to address CO 2 adsorption behavior via different adsorbents and techniques (Lee et al 2002;Harlick and Tezel 2004;Li and Tezel 2007;Siriwardane et al 2003;Jaramillo and Chandross 2004;Khelifa et al 2004;Li et al 2000Li et al , 2008Walton et al 2006;Maurin et al 2005;Gao et al 2004;Kusakabe et al 1997, Plant et al 2006Sebastian et al 2007;Chou and Chen 2004;Othman et al 2006;Zheng and Gu 1998). Yong et al (2002) reviewed the adsorption of CO 2 on different adsorbents at relatively high temperatures.…”

NaY zeolite particles with a high surface area of 723 m 2 /g were synthesized by a hydrothermal method. Adsorption isotherms of pure gases CO 2 and N 2 on the synthesized NaY particles were measured at temperatures 303, 323, 348, 373, 398, 423, 448 and 473 K and pressures up to 100 kPa. It was found that the adsorption isotherm of CO 2 on the synthesized zeolite is higher than that on other porous media reported in the literature. All measured adsorption isotherms of CO 2 and N 2 were fitted to adsorption models Sips, Toth, and UNILAN in the measured temperature/pressure range and Henry's law adsorption equilibrium constants were obtained for all three adsorption models. The adsorption isotherms measured in this work suggest that the NaY zeolite may be capable of capturing CO 2 from flue gas at high temperatures. In addition, isosteric heats of adsorption were calculated from these adsorption isotherms. It was found that temperature has little effect on N 2 adsorption, while it presents marked decrease for CO 2 with an increase of adsorbate loading, which suggests heterogeneous interactions between CO 2 and the zeolite cavity.

“…[117] Zeolite 5A gives higher CO 2 selectivities for dry gases than BPL Carbon, with reported selectivities of 196, 59, and 331 for the same three gas mixtures. [117] Not all zeolites are this selective; the selectivities of zeolite 13X [118] and zeolite b [119] for CO 2 /CH 4 are 2-24 and 28, respectively. These widely available materials define several cautionary notes related to examining data for MOFs.…”

Can Metal–Organic Framework Materials Play a Useful Role in Large‐Scale Carbon Dioxide Separations?

2010

Metal-organic frameworks (MOFs) are a fascinating class of crystalline nanoporous materials that can be synthesized with a diverse range of pore dimensions, topologies, and chemical functionality. As with other well-known nanoporous materials, such as activated carbon and zeolites, MOFs have potential uses in a range of chemical separation applications because of the possibility of selective adsorption and diffusion of molecules in their pores. We review the current state of knowledge surrounding the possibility of using MOFs in large-scale carbon dioxide separations. There are reasons to be optimistic that MOFs may make useful contributions to this important problem, but there are several critical issues for which only very limited information is available. By identifying these issues, we provide what we hope is a path forward to definitively answering the question posed in our title.

“…14 Various mesoporous and microporous adsorbents (carbons [15][16][17][18][19] , MOFs 15,20,21 , zeolites 11,15,[22][23][24][25] , clays 26,27 , and silica-based mesoporous materials 28,29 ) have been proposed for CO2 adsorption/separation from biogas. Although, these adsorbents are still not ideal for CO2…”

We explore the potential of these materials for CO2/CH4 separation, by studying the adsorption of pure CO2and pure CH4 gases. The aminated periodic mesoporous phenylene-silica with the smallest pore size is the best adsorbent to CO2, presenting a Henry's constant of 0.56 mol kg -1 ·bar -1 at 35 ºC. However, the corresponding Henry's constant for CH4 is extremely low (0.06 mol·kg -1 ·bar -1 at 35 ºC). It is observed a direct correlation between the % of T 2 SMP silanols species and the values of the Henry's constants, which may be used to theoretically predict experimental CO2 Henry's constants of potential adsorbents.3
