Under more severe conditions of calcination at 950 in 100% CO 2 following carbonation at 650 in 100 % CO 2 , the best overall performance was for a sorbent with 30 wt% CaZrO 3 : 70 wt% CaO (the highest Zr ratio studied), with an initial uptake of 0.36 g-CO 2 /g-sorbent decreasing to 0.31 g-CO 2 /g-sorbent at the 30 th cycle.Electron microscopy revealed CaZrO 3 was present in the form of ≤ 0.5 µm cuboid and 20-80 nm particles dispersed within a porous matrix of CaO/CaCO 3 ; the nanoparticles are considered to be the principal reason for promoting multicycle durability.

CO2 Capture Performance Using Biomass-Templated Cement-Supported Limestone Pellets

“…Several techniques have been proposed in previous works such as precipitation methods, 5,6 organic acid treatments, [7][8][9][10][11] chemical doping, 12,13 hydration, 12,[14][15][16][17] and synthesis techniques of highly efficient sorbents, i.e. sol-gel method, [18][19][20][21] carbon template, 19,22 and biomass template.…”

Role of MgxCa1−xCO3 on the physical–chemical properties and cyclic CO2 capture performance of dolomite by two-step calcination

“…One promising method is the development of highly efficient sorbents to improve long-term performance [8][9][10][11][12][13][14][15][16][17][18][19][20]. The other is using simple reactivation routes to reduce the rate of decay in reactivity [3,[21][22][23].…”

Spray‐Dried Sodium Zirconate: A Rapid Absorption Powder for CO2 Capture with Enhanced Cyclic Stability

“…As mentioned in the Introduction, there is a wide literature on other high‐temperature powder sorbents for CO 2 capture, most notably for CaO powders in which refractory additives are introduced, for example, ZrO 2 to suppress the natural densification (partial sintering) and loss of porosity that degrades cycle on cycle the CaO performance, as outlined in the Introduction. Often, very complex chemical solution precipitation reactions are employed to promote adequate mixing of the two components.…”

“…A uniform distribution of the second phase is essential to minimize densification of the active CaO phase and suppress multicycle degradation. The performance of a range of CaO‐based sorbents is summarized in the study of Zhao et al . The more complex (and costly) the processing technique, for example, sol‐gel or chemical templating, the finer the particle size, and the more uniform the dispersion.…”
