Summary: The CO2 uptake performance of three waste calcium-based sorbents under different cycle numbers was studied using TGA and characterization analysis. The results showed that the carbonation conversion rate of the sorbents decreased as the number of cycles increased, with chicken eggshells exhibiting the most significant decrease rate. Carbide slag and analytical reagent-grade calcium carbonate showed a linear decline trend. The formula for cyclic carbonation reactivity decay was redefined based on the specific surface area of the sorbents.

Summary: This study found that increasing calcination temperature reduces the reactivity of solid sorbents, while incomplete calcination of limestone significantly alters its CO2 absorption capacity. The semi-empirical method proposed by the authors accurately estimates the fast reaction-controlled carbonation extent of different natural limestones under varying calcination conditions.

Summary: The calcium looping technology is a promising method for CO2 capture and storage. Previous studies have focused on evaluating this technology using combustion flue gas, while little is known about its performance when capturing CO2 from biogas or gases resulting from hydrothermal carbonization. This experimental study assesses the performance of calcium looping for biogas and finds improved CO2-capture performance compared to combustion flue gas.

Summary: This study demonstrates a novel approach to carbon capture and storage in UHPC, reducing its carbon footprint by replacing cement with GGBS and capturing CO2 in fresh mixes. Results show that carbon curing slightly decreases compressive strength but significantly improves carbonation in UHPC mixes.

Summary: This study investigated the impact of contaminants in biomass gasification producer gas on the CO2 capture performance of a CaO and Fe2O3 based sorbent material. Experimental results showed effective CO2 capture in the initial stages and a catalytic effect of the sorbent material in removing contaminants from the gas.

Summary: The study fabricated calcium-based sorbents with a starch pore former and a cement stabilizer for high-temperature CO2 capture. The addition of 10% starch template and 20% cement resulted in the highest CO2 uptake after 20 cycles. Different steam reactivation methods were explored to restore CO2-capture performance for the modified sorbents.

Summary: The study evaluated the development of a Ca-based CO2 capture sorbent from a limestone-rich mine waste via aqueous mineral carbonation. It was found that optimal dissolution and carbonation of calcium occurred at 2.5% pulp density, resulting in the production of pure calcite during the process. The promising CO2 uptake capacity of the developed sorbent suggests its potential for direct CO2 capture.

Summary: Fulvic acid (FA) was used to modify CaO for improved CO2 capture. Under optimal conditions, the carbonation conversion rate (CCR) of FA/CaO was 31% higher than that of original CaO. The addition of FA improved the microstructure of CaO, increasing its specific surface area and pore size, and enhancing CO2 capture performance.

Summary: Calcium looping (CaL)-based solar to thermochemical energy storage is a promising option for long-term thermal energy storage in concentrated solar power generation. In this study, multi-doping of transition metals and CaCl2 was investigated to enhance the optical absorption and carbonation reactivity of synthetic CaO-based materials. The proposed materials exhibited significantly enhanced optical absorption and maintained high performance throughout multiple cycles of CaL reactions. The reaction mechanism was studied, and a salt-promoted carbonation mechanism was proposed to improve the mass transfer of Ca2+O2- to adsorbed CO2. Based on the findings, the synergistic use of CaCl2 multi-doping method for synthetic CaO designs is suggested.

Summary: This study investigated a new preparation method of synthetic calcium oxide-based pellets for DAC process. Their CO2 capture performance was tested experimentally in a fixed-bed column and characterized by BET analysis, mercury porosimetry, X-ray diffraction, and scanning electron microscopy. It was found that higher heating rates during the precursor calcination process and higher relative humidities during the carbonation process led to higher CO2 capture efficiencies. All prepared pellets exhibited good mechanical stability.

Summary: In this study, the mechanism of carbonation reaction through CO2 capture by synthesizing ternary (CaO-Al2O3-Fe2O3) compounds was investigated. It was found that the synthetic SCAF underwent carbonation reaction at different sintering temperatures, and the reaction became more active with increasing reaction time. Therefore, the synthesized SCAF in this study is expected to be an effective material for CO2 capture.

Summary: In this study, the carbonation kinetics of calcium silicate hydrate (C-S-H) with varying calcium to silica ratio (Ca/Si) were investigated. The results showed three distinct periods in the carbonation process and quantitatively characterized the evolution of carbonation products. The findings not only enhance our understanding of the deterioration of cementitious materials under carbonation, but also provide new insights into CO2 capture using C-S-H.

Summary: This study investigates the influence of loading strategy for promoters on the structure and sorption behavior of calcium-based sorbents. The results show that the two-step synthesis method leads to higher promoter loading, improved CO2 sorption capacity and retention rate, and even introduces a self-activation effect.
