“…The order of adsorption capacity of gases on zeolites is CO 2 [ N 2 [ CH 4 [ H 2 . This pattern can be explained by the fact that CO 2 has greater quadrupole moment (4.30 9 10 -26 esu cm 2 ) and polarizability (2.65 9 10 -24 cm 3 ) than N 2 (quadrupole moments: 1.52 9 10 -26 esu cm 2 ; polarizability: 1.76 9 10 -24 cm 3 ) and CH 4 (quadrupole moment: 0; polarizability: 2.60 9 10 -24 cm 3 ) (Hudson et al 2012;Jiang et al 2013).…”

In the last few decades of industrialization, the concentration of CO 2 in the atmosphere had increased rapidly. Different organizations have invested considerable funds in research activities worldwide for CO 2 capture and storage. To date, significant work has been done and various technologies have been proposed for CO 2 capture and storage. Both adsorption and absorption are promising techniques for CO 2 capture, but low-temperature adsorption processes using solid adsorbents are the prevailing technique nowadays. In this review paper, a variety of adsorbents such as carbonaceous materials, dry alkali metal-based sorbents, zeolites, metal-organic frameworks (MOFs) and microporous organic polymers (MOPs) have been studied. Various methods of chemical or physical modification and the effects of supporting materials have been discussed to enhance CO 2 capture capacity of these adsorbents. Low-temperature (\100°C) adsorption processes for CO 2 capture are critically analyzed and concluded on the basis of information available so far in the literature. All the information in CO 2 adsorption using different routes has been discussed, summarized and thoroughly presented in this review article. The most important comparative study of relatively new material MOFs and MOPs is carried out between the groups and with other sorbent as well.

“…Increasing the aging time maximizes crystallinity and decreases the crystalline particle size in zeolites. Furthermore, crystallinity and nanoparticles exhibit promising performance for CO 2 adsorption (Ginter et al 1992;Jiang et al 2013). Some of the physical properties of the zeolites are listed in Table 4.…”

“…The current absorption method of utilizing various amine solutions to capture CO 2 is facing challenges from the high energy requirements in the regeneration process, corrosion and the disposal of toxic byproducts [5,6]. As an alternative, researchers have been working on the use of novel solid adsorbents such as metal-organic frameworks (MOFs) [7,8] and nitrogen-containing porous organic polymers (POPs) [9,10] with lower heat capacities than the more commonly known zeolites [11,12] and carbons materials [13,14]. Recently, POPs which can be constructed from light-weight elements linked by strong covalent bonds have attracted increasing attention for gas adsorption, storages and separation owing to their high stability against moisture, chemical stability with long lifetimes and easy handling [15].…”

“…Zeolites are porous aluminosilicates with a high surface area and a high thermal stability and are used in applications such as catalysis [1,2], ion exchange [3,4] and in separation and purification processes [5,6]. Currently, the potential use of low-cost zeolites for carbon capture is to mitigate the anthropogenic release of carbon dioxide, e.g., combustion of fossil fuels is attracting a significant interest [7,8,9].…”

Methylcellulose-Directed Synthesis of Nanocrystalline Zeolite NaA with High CO2 Uptake

Zeolite NaA nanocrystals with a narrow particle size distribution were prepared by template-free hydrothermal synthesis in thermo-reversible methylcellulose gels. The effects of the amount of methylcellulose, crystallization time and hydrothermal treatment temperature on the crystallinity and particle size distribution of the zeolite NaA nanocrystals were investigated. We found that the thermogelation of methylcellulose in the alkaline Na2O-SiO2-Al2O3-H2O system played an important role in controlling the particle size. The synthesized zeolite nanocrystals are highly crystalline, as demonstrated by X-ray diffraction (XRD), and scanning electron microscopy (SEM) shows that the nanocrystals can also display a well-defined facetted morphology. Gas adsorption studies on the synthesized nanocrystalline zeolite NaA showed that nanocrystals with a size of 100 nm displayed a high CO2 uptake capacity (4.9 mmol/g at 293 K at 100 kPa) and a relatively rapid uptake rate compared to commercially available, micron-sized particles. Low-cost nanosized zeolite adsorbents with a high and rapid uptake are important for large scale gas separation processes, e.g., carbon capture from flue gas.
