“…PSA is commercially used for gas separation, in hydrogen production and in the removal of CO 2 from natural gas (Diagne et al, 1995;Yong et al, 2002;IPCC 2005). However, the key challenge of CO 2 capture using adsorption technology is low capacity and selectivity for current adsorbents, which limits its application for large scale CO 2 removal.…”

“…However, its CO2 sorption capacity suddenly decreases to 1.43 wt % at 250°C (18). In contrast, our oxides can take up 5-6 wt % at 350°C, and their sorption capacity is only slightly decreased at 400-500°C (9).…”

Various X n Y 3-n Al-hydrotalcite-like compounds (HTlcs) were synthesized by the constant pH coprecipitation method with the (X 2+ + Y 2+ )/Al 3+ molar ratio fixed at 3.0. Well-mixed oxides X n Y 3-n AlO were derived from corresponding HTlcs precursors upon calcination. Physicochemical characterization with X-ray diffraction analysis, Fourier transform infrared spectroscopy, thermogravimetric analysis (TGA), and the Brunauer-Emmett-Teller equation indicates that the derived oxides are of either periclase or spinel phase, with an interparticle pore diameter of 9.6-15.4 nm. These oxides generally show a high CO 2 adsorption capability at 350°C. For example, CaCoAlO captures 1.39 mmol/g of CO 2 (i.e., 6.12 wt %) from a gas mixture (8% CO 2 in N 2 ) at 350°C and 1 atm in a fixed-bed reactor within 20 min. All other mixed oxides adsorb 0.87-1.28 mmol/g (3.83-5.63 wt %) of CO 2 . Therefore, these mixed oxides are potential cost-effective CO 2 sorbents for environmental remediation. In addition, the CO 2 adsorption behavior is well-described with the deactivation model. The species of CO 2 formed on the sorbents are various carbonates, as revealed by in situ IR spectra as well as TGA.

“…These sorbents include carbon [16] and silica [17] based sorbents and zeolites [16]. The sorbents are typically activated (by heat) or functionalized with amines to increase carbon dioxide selectivity.…”

Effective capture of atmospheric carbon is a key bottleneck preventing non bio-based, carbon-neutral production of synthetic liquid hydrocarbon fuels using CO 2 as the carbon feedstock. Here we outline the boundary conditions of atmospheric carbon capture for recycle to liquid hydrocarbon fuels production and re-use options and we also identify the technical advances that must be made for such a process to become technically and commercially viable at scale. While conversion of atmospheric CO 2 into a pure feedstock for hydrocarbon fuels synthesis is presently feasible at the bench-scale -albeit at high cost energetically and economically-the methods and materials needed to concentrate large amounts of CO 2 at low cost and high efficiency remain technically immature. Industrial-scale capture must entail: (1) Processing of large volumes of air through an effective CO 2 capture media and (2) Efficient separation of CO 2 from the processed air flow into a pure stream of CO 2 . 4 ACKNOWLEDGMENTS
