“…CCS is important to mitigate the global warming and its consequences by capture of CO 2 from large anthropogenic sources. Aqueous alkanolamines and chilled ammonia based absorption process [5,6], membrane separation process [7,8], novel cryogenic process [9], algal biomass process [10,11] and porous solid adsorption process [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] are most commonly used for CO 2 capture. Among these processes aqueous alkanolamine especially monoethanolamine (MEA) and diethanolamine (DEA) based absorption process is well known with significant commercial application for CO 2 capture.…”

“…Adsorption is an alternate and cost effective CO 2 capture process. In the recent years microporous activated carbon [22,23], metal organic frameworks (MOFs), zeolites [24,25] and amine functionalized silica and foams based adsorption processes [12][13][14][15][16][17][18][19][20][21][26][27][28][29] have shown strong potential for CO 2 capture.…”

“…Ko et al [16] modified the SBA-15 by primary, secondary and tertiary amines and reported the adsorption capacity of 0.95, 0.75 and 0.17 mmol g À1 respectively for these amines at 25°C. Liu et al [28] functionalized the KIT-6 by tetraethylenepentamine using wet-impregnation method and showed an adsorption capacity 2.9 mmol g À1 at 60°C using gas chromatograph (GC) with a 10% CO 2 in feed gas. Linneen et al [40] functionalized the aerogel with APTES using grafting method and showed the CO 2 adsorption capacity 0.67 mmol g À1 at 1 bar and 25°C.…”

“…Basically, owing to the higher concentration of amine groups, larger amounts of primary amine, and lower viscosity, higher capacities can be obtained by using TEPA as compared with that of PEIs. However, the cyclic stability of using TEPA is questionable due to its lower thermal stability which led to amine loss during desorption at elevated temperatures (Chen et al, 2009;Liu et al, 2010;Qi et al, 2011). A similar theory can be applied to linear PEI as well.…”

CO 2 capture represents the key technology for CO 2 reduction within the framework of CO 2 capture, utilization, and storage (CCUS). In fact, the implementation of CO 2 capture extends far beyond CCUS since it will link the CO 2 emission and recycling sectors, and when renewables are used to provide necessary energy input, CO 2 capture would enable a profitable zero-or even negative-emitting and integrated energy-chemical solution. To this end, highly efficient CO 2 capture technologies are needed, and adsorption using solid adsorbents has the potential to be one of the ideal options. Currently, the greatest challenge in this area is the development of adsorbents with high performance that balances a range of optimization-needed factors, those including costs, efficiency, and engineering feasibility. In this review, recent advances on the development of carbon-based and immobilized organic amines-based CO 2 adsorbents are summarized, the selection of these particular categories of materials is because they are among the most developed low-temperature (<100°C) CO 2 adsorbents up to date, which showed important potential for practical deployment at pilot-scale in the near future. Preparation protocols, adsorption behaviors as well as pros and cons of each type of the adsorbents are presented, it was concluded that encouraging results have been achieved already, however, the development of more effective adsorbents for CO 2 capture remains challenging and further innovations in the design and synthesis of adsorbents are needed.Keywords: CCUS, CO 2 capture, adsorption, energy, material science INTRODUCTION CO 2 CAPTURE AND AN INTEGRATED ENERGY-CHEMICAL SOLUTIONThe atmospheric CO 2 concentration now exceeds 400 ppm (CO2Now.org, 2014), and its continuous increase is believed to be the major factor leading to global warming and climatic change (Crowley, 2000;Held and Soden, 2000;Patz et al., 2005). Kaya et al. and Hoffert et al. have quantified net CO 2 emissions in terms of population, economic activity, and energy-related factors using Eq. 1 (Kaya, 1995;Hoffert et al., 1998).where C is the net CO 2 emission, P is population, GDP is the gross domestic product that is used here as an indicator of economyrelated factor, and E is energy production. Therefore, GDP/P is the Per capita GDP, and E/GDP can be regarded as the energy intensity during production that is closely related to the efficiency of energy utilization. The last term, C/E, represents the carbon intensity during energy production. As for the development of the human society and life quality, it is improper to limit population and production, which means there is no solution to CO 2 reduction from the first and second term in Eq. 1. On the other hand, increase in the energy production/utilization efficiency and control of the carbon footprint during energy processes are the major strategies for CO 2 sequestration (third and fourth term in Eq. 1). The complete decarbonization of energy is believed to be the ultimate solution for the long-term sustainability, ...

“…On this theme, the overwhelming majority of research has focused on silica-based amine solid sorbents. Different kinds of silicas such as MCM-41 [19][20][21], SBA-15 [22,23], KIT-6 [24], and silica foams [25,26] have been explored as supports. These studies show that aminefunctionalized silicas possess promising CO 2 uptake under simulated flue gas conditions and further reveal that the surface area, pore size and pore volume of the supports determine the CO 2 sorption capacity of the composite sorbents [27].…”
