The seed-swelling method was adopted to synthesized the porous copolymer of 1-allyl-3-methylimidazolium tetrafluoroborate and acrylonitrile P([amim]BF4-AN). The samples were characterized by IR, DSC and CO2sorption was investigated by determining equilibrium data. The effects of the amount of initiator and swelling time on the porous structure and CO2sorption were discussed in detail. The results indicated that porous P([amim]BF4-AN) with benzoyl peroxide (BPO)0.1g and swelling 20h has the higher CO2sorption capacity.

Abstract The aim of this work is to identify solid sorbents for CO2 capture for coal and biomass syngas conditioning and cleaning by means of a sorption-enhanced reaction process. Hydrotalcite-like compounds (HTlcs) were synthesized with and without K2CO3 impregnation. Samples were characterized by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) and Barrett–Joyner–Halenda (BJH) porosimetry after synthesis and after capture tests, respectively. Sorption and desorption tests were performed in a fluidized bed reactor, under cyclic conditions, at two different temperature levels: 350/450°C and 600/700°C. At low temperature only the Mg–Al HTlcs K promoted samples showed stability and sorption capacity comparable with literature values. On the other hand, results at high temperature indicate that the mixed Mg-Ca-Al HTlcs samples exhibit the best behavior with the highest sorption capacity (1.7 mmolCO2/g) almost stable over 5 sorption/regeneration cycles; furthermore, addition of steam allowed increasing their reactivity by 70% compared to the dry value. This type of sorbent could be a promising candidate to prepare a bifunctional sorbent–catalyst for sorption-enhanced processes, taking place directly in the fluidized bed gasifier, or downstream the reactor for adjustment of gas composition before further conversion in gaseous energy carriers.

CO2 capture and separation by ionic liquid is one of the fastest growing branches in ionic liquid technology. The aim of this research was to synthesize the ionic liquid polymer incorporating activated carbon and investigating its performance for CO2 capture and separation. The ionic liquid monomers 1-vinyl-3-ethylimidazolium bromide, [veim][Br] and 1-vinyl-3-ethylimidazolium bis (trifluoromethyl-sulfonyl) imide, [veim][Tf2N] were first synthesized and then polymerized into ionic liquid polymers incorporating activated carbon. The purity of the [veim][Br] and [veim][Tf2N] was verified by 1H NMR, 13C NMR and Ion Chromatography. Both monomers were proved to be in high purity. The elemental composition of both polymer materials synthesized were examined using energy dispersive X-ray spectroscopy (EDX) and the morphology of the synthesized material was observed using field emission scanning electron microscopy (FESEM). The results revealed that activated carbon has been successfully incorporated into the lattice structure of polymer materials. The fabricated polymer materials would be expected to have higher CO2 capture capability as it combines both the absorption and adsorption mechanism for CO2 apprehension and sequestration.

CO2 levels in the atmosphere are increasing exponentially. The current climate change effects motivate an urgent need for new and sustainable materials to capture CO2. Porous materials are particularly interesting for processes that take place near atmospheric pressure. However, materials design should not only consider the morphology, but also the chemical identity of the CO2 sorbent to enhance the affinity towards CO2. Poly(ionic liquid)s (PILs) can enhance CO2 sorption capacity, but tailoring the porosity is still a challenge. Aerogel’s properties grant production strategies that ensure a porosity control. In this work, we joined both worlds, PILs and aerogels, to produce a sustainable CO2 sorbent. PIL-chitosan aerogels (AEROPILs) in the form of beads were successfully obtained with high porosity (94.6–97.0 %) and surface areas (270–744 m2/g). AEROPILs were applied for the first time as CO2 sorbents. The combination of PILs with chitosan aerogels generally increased the CO2 sorption capability of these materials, being the maximum CO2 capture capacity obtained (0.70 mmol g−1, at 25 °C and 1 bar) for the CHT:P[DADMA]Cl30% AEROPIL.
