Summary: The study shows that inert additive-doped CaO-based CO2 adsorbents can be synthesized in one pot by the mechanochemical method, producing methane instead of CO2 emission. The prepared CaO@C and CaO@MgO@C composites exhibit high CO2 adsorption capacity and superior cycling stability, with much lower activity losses after 30 cycles compared to conventional adsorbents. This work provides a novel, simple, solution-free, and sustainable strategy for synthesizing effective CaO-based CO2 adsorbents.

Summary: The capture of CO2 from industrial flue gas by CaO in fluidized bed calcium looping processes is an effective way to reduce greenhouse gas emissions. This study developed an expression for the diffusivity of the product layer that takes into account the carbonation time using fractal-like dynamics concepts. The proposed fractal model based on the canonical random pore model demonstrated superior accuracy in predicting CO2 diffusion in the product layer under realistic operating conditions.

Summary: The excessive emission of anthropogenic CO2 has led to the greenhouse effect, causing serious problems to the environment and human society. To address this issue, Al-promoted CaO-based solid sorbents were produced on a kilogram scale per batch using a simple co-precipitation technique, which improved the CO2 sorption performance of the sorbents. The optimized preparation conditions resulted in the successful synthesis of a 6-kg sorbent powder with favorable CO2 capture performance, and pelletization methods were used to further enhance the sorbent pellets' CO2 sorption capability and anti-attrition resistance.

Summary: This study sought to use organic acid-rich torrefaction condensate (TC) as a replacement for commercial acetic acid (AC) in the acidification treatment of CaO sorbent to enhance its CO2 capture performance. The modified sorbents with TC exhibited better cyclic stability compared to the AC-modified ones. The presence of carbon deposition from TC, which acted as a spacer and protective overlay to slow down the sintering of CaO particles, was believed to be the reason for the improved cyclic stability.

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: Novel MgO-doped CaO sorbent pellets exhibit excellent CO2 adsorption capacity and adsorption rate due to the homogeneous dispersion of MgO and its effects on the physical structure of sorbents, effectively inhibiting sintering of CaO and retaining adsorption capacity during multiple cycles. Mesopores and macropores contribute to significant volume changes during operation cycles. Ca2Mg1 sorbent pellets show favorable CO2 capture capacity, average adsorption rate, and conversion rate of CaO after 30 cycles.

Summary: A Zr-doped CaO sorbent with an average filament diameter of about 160 nm was fabricated using electrospinning. The sorbent showed an initial CO2 uptake capacity of 12.1 mmol/g, a specific surface area of 79 m(2)/g, an indentation Young's modulus of 520 MPa, and a hardness of 1.6 MPa. After 50 carbonation/decarbonation cycles, the sorbent still exhibited a decent CO2 uptake capacity of 9.7 mmol/g due to the uniform distribution of CaZrO3 in the CaO nanofibers.

Summary: In this study, three calcium-based metal frameworks were used as precursors to obtain nano CaO through a two-step thermal transition process, and it achieved a fast adsorption capacity of 11.8 mmol g-1. The improvement in cyclic performance was attributed to the gradual transformation of the precursor structure into nanosheets, preventing further aggregation of CaO particles during thermal transition. Pore structure was found to have little influence on the adsorption performance, suggesting that high stability can be achieved by avoiding particle sintering. This study highlights the importance of precise tailoring of nano-CaO for CO2 fast adsorption.

Summary: This study reports a method to prepare a novel stable CaO-based sorbent by utilizing municipal solid waste incineration (MSWI) bottom ash. The stabilizer derived from the bottom ash promoted the dispersion of CaO and increased the surface area and pore size of the sorbents. The addition of Al2O3 and SiO2 from the bottom ash reacted with CaO to maintain the porous structure of the sorbents. The optimum carbonation temperature for the sorbents was found to be 700 degrees C, and after 20 cycles, the highest CO2 uptake was achieved by the BAS(20 wt%)/CaO sorbent, with a value of 0.14 gCO2/gsorbent.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
