“…This trend can be observed in Table 4 (Bonenfant et al 2007;Kamiuto et al 2002;Li et al 2013;Yu et al 2012). The study of Siriwardane et al (2003) suggested that natural zeolites with the highest surface area and sodium (Na) content yield the highest adsorption capacity for CO 2 .…”

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.

“…A wide variety of materials has been investigated as CO2 adsorbents, including metal oxides [9], activated carbons [10], zeolites [11,12], and metal-organic frame-works [13]. Alkali metal or alkaline earth metal oxides-based adsorbents have achieved high CO2 adsorption capacity [14].…”

Three kinds of inorganic alkali are introduced into tetraethylenepentamine (TEPA)-and polyethyleneimine (PEI)-modified MCM-41 as the CO2 adsorbents. FT-IR and TGA are used to characterize the surface groups and the thermal stability of adsorbents. Chemical titration method is used to measure the alkali amounts of adsorbents. Thermo-gravimetric analysis with 10% CO2/90% N2 as the simulated flue gas is used to test the CO2 adsorption performance of adsorbents. The results show that all three kinds of inorganic alkali-containing adsorbents exhibit higher CO2 adsorption capability than traditional TEPA and PEI modified samples. Ca(OH)2 and PEI modified samples exhibit the highest adsorption capacity and recyclable property. The introduction of inorganic alkali changes the chemical adsorption mechanism between CO2 and adsorbent surface due to the increased hydroxyl groups. The CO2 adsorption capacities have a linear dependence relation with the alkali amounts of adsorbents, indicating that alkali amount is a critical factor for the exploration of novel adsorbents.
