“…Although most zeolites commercially available are produced synthetically [19][20][21][22], an increasingly higher demand of natural zeolites, such as Clinoptilolite, Mordenite, Erionite, Ferrierite and Phillipsite, for gas separation is currently being produced [6,23,24]. Natural zeolites usually require previous activation and packaging steps which not always makes their use profitable.…”

“…Within TSA technologies, the specific case in which the solid is heated by the Joule effect is commonly referred to as electric swing adsorption (ESA) [5,6]. The vast majority of studies dealing with CO 2 post-combustion capture by means of PSA or TSA technologies use zeolites as adsorbent [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Zeolite 13X is by far the adsorbent most extensively studied in CO 2 separation processes, due to its high selectivity to CO 2 [21].…”

A commercial activated carbon supplied by Norit, R2030CO2, was evaluated as CO 2 adsorbent under conditions relevant to post-combustion CO 2 capture (ambient pressure and diluted CO 2 ). It has been demonstrated that this carbon possesses sufficient CO 2 /N 2 selectivity in order to efficiently separate a binary mixture composed of 17 % CO 2 in N 2 . Moreover, this carbon was easily completely regenerated and it did not show capacity decay after ten consecutive cycles. Three different regeneration strategies were compared in a single-bed adsorption unit: temperature swing adsorption (TSA), vacuum swing adsorption (VSA) and a combination of them, vacuum and temperature swing adsorption (VTSA). Through a simple two step TSA cycle, CO 2 was concentrated from 17 to 43 % (vol). For the single-bed cycle configurations, the productivity and CO 2 recovery followed the sequence: TSA

“…So the separation, recovery and storage/utilization of CO 2 have attracted considerable attention in recent years. CO 2 can be removed from flue gas and waste gas streams by various methods such as membrane separation, wet absorption, and dry absorption [1][2][3][4]. However, these methods need to consume a lot of energy.…”

Using diatomite and analytical pure SiO 2 as silicon sources, Li 4 SiO 4 sorbents for high temperature CO 2 capture were prepared through solid-state reaction method. Phase composition was analyzed by X-ray diffraction, and the CO 2 absorption capacity and absorptoin-desorption performance were studied by the simultaneous thermal thermogravimetric analyzer (TG-DSC). The results showed that silicon source had an important influence on CO 2 absorption properties. The kinetic parameters for the chemisorption and diffusion processes were obtained by the isothermal study for different silicon sources. The results showed that the activation energies for these two processes were estimated to be 105.427 and 35.928 kJ/mol for the sample with analytical pure SiO 2 (AS). While for the sample with diatomite (DS), the activation energies for these two processes were estimated to be 78.500 and 20.439 kJ/mol, respectively. The increasing CO 2 concentration in the atmosphere due to fossil fuel burning has been considered as a major contributor to the global warming. So the separation, recovery and storage/utilization of CO 2 have attracted considerable attention in recent years. CO 2 can be removed from flue gas and waste gas streams by various methods such as membrane separation, wet absorption, and dry absorption [1][2][3][4]. However, these methods need to consume a lot of energy. Hence, the materials with high CO 2 capture capacity at high temperature are desirable. In recent years, the development of regenerable sorbents for high temperature CO 2 capture has received increasing attention [5][6][7]. Compared with other sorbents, Li 4 SiO 4 has the better CO 2 absorption properties over a wide range of temperature and CO 2 concentration [8,9]. In order to study the absorption mechanism of Li 4 SiO 4 materials, some researchers made some kinetic study about Li 4 SiO 4 materials [10]. However, kinetic study about different silicon sources has not been reported.In this paper, we firstly developed novel low-cost Li 4 SiO 4 sorbents for high temperature CO 2 capture using diatomite as silicon source. The effect of different silicon sources on the absorption capacity was investigated by studying their kinetic characteristics. In the following paper, DS and AS stand for diatomite and analytical pure SiO 2 , respectively.
