Summary: Calcium looping is a feasible CO2 capture technology, but chlorine in fuels can impact the performance of calcium-based sorbents. Experimental results showed that the presence of HCl can increase sorbent reactivity towards CO2 and decrease CO2 diffusional resistance by changing particle morphology during carbonation using Canadian limestone. Additionally, full sorbent dechlorination can be achieved under typical oxy-fuel calcination conditions, with over 99% HCl capture without affecting sorbent CO2 capture performance when steam is present during both carbonation and calcination.

Summary: Calcium looping for CO2 capture involves cyclic calcination/carbonation of CaO, with fuel combustion supplying energy for the process. The presence of unburned char in the calciner can lead to CO generation in the carbonator, which can reduce NO in flue gases. The study found that CaO exhibits efficient catalytic effect on NO removal by CO, with high temperature and CO concentration leading to higher NO removal efficiency in the presence of CaO. The optimal carbonation temperature for better NO removal and CO2 capture was determined to be 650 degrees C, and the study also highlighted the beneficial effects of high CaO content and porous structure of calcium-based sorbents on NO removal by CO.

Summary: Water (H2O) in the carbonation and sulfation reactions during calcium looping has dual effects, reducing the negative impact of sulfur dioxide (SO2) on carbonation. At certain concentrations, H2O can enhance sulfation while inhibiting carbonation, a phenomenon that needs to be taken into consideration.

Summary: A process for carbon capture from limestone calcination in a steam atmosphere generated by hydrogen and oxygen combustion has been developed. This process allows for carbon dioxide capture by condensing steam from exhaust gases, eliminating the energy-intensive step of carbon dioxide separation. A techno-economic analysis shows that cost parity can be achieved once the price of hydrogen reaches a certain range.

Summary: Capture and conversion of CO2 from optimal scenarios into fuels or chemicals provide a viable solution to combat climate change. The proposed synergistic integration of catalytic calcium-looping gasification of biochar can capture and in situ convert CO2. Experimental tests and characterizations showed that the mixture of limestone and K2CO3-impregnated biochar can enhance decarbonation kinetics and CO yield, maintaining stable CO2 conversion at lower temperatures. The process demonstrated practical scalability and cost-effectiveness, opening a unique direction for net-negative emission.

Summary: We report an efficient process for dehydrogenating formaldehyde in alkaline solution using carbon nanotubes as catalysts with the involvement of molecular O-2 in a unique reaction mechanism. The superior catalytic performance of carbon nanotubes is attributed to their sp(2)-carbon-rich surface, hydrophilicity, and abundant surface defects, which serve as the most plausible active sites. The activation of adsorbed molecular oxygen on carbon nanotubes leading to peroxide species is found to be crucial for C-H activation and efficient hydrogen production. The cost-effective carbon-based dehydrogenation catalysts provide new opportunities for the development of novel liquid organic hydrogen carrier technologies.

Summary: This study presents a novel catalytic chemistry for the demethylenation of benzyl alcohol to phenol using a combination of an earth-abundant transition metal oxide (CuO) catalyst and high frequency ultrasound (HFUS). The reaction takes place in water and at room temperature. By characterizing the catalyst, analyzing the chemistry and acoustics, using isotope labelling and density functional theory computations, the researchers unveil the molecular reaction mechanism, which involves benzaldehyde as an intermediate. Water is not only a benign solvation medium, but also directly participates in the reaction by undergoing dissociation due to sonolysis. The adsorption of the OH from water on the catalyst surface inhibits recombination and activates the C-H bond in benzyl alcohol, leading to the formation of benzaldehyde and its incorporation into the phenyl ring to form phenol.

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.
