Summary: A fixed-bed reactor was used to simulate CO2 gasification and examine the transformation of alkali and alkaline earth metals (AAEMs) in biomass. The study found that the release of AAEMs followed a specific sequence and the alkali metals mainly appeared as water-soluble inorganic salts. Higher temperatures led to the formation of compounds with other elements. Larger particle sizes were beneficial for the transformation of potassium from water-soluble to organic forms, particularly in candlenut wood.

Summary: The effects of alkali metals (KCl, NaCl) and alkaline earth metals (CaO, MgCl2) on the evolution of nitrogen-containing compounds and product distribution during the pyrolysis of phenylalanine were investigated. TG-IR was used to track the changes in nitrogen-containing gases (NH3, HCN, HNCO) with temperature and their final release amounts. The pyrolysis reaction paths of phenylalanine were simulated using the M06-2X method and 6-31g(d) basis set, and the influence mechanism of AAEMs on the evolution process of nitrogen-containing compounds was explored at the molecular level. The results showed that KCl promoted the release of HCN and HNCO while inhibiting the release of NH3, whereas NaCl inhibited the production of NH3 and HCN and promoted the production of HNCO. Both CaO and MgCl2 promoted the release of HCN and NH3 and inhibited the release of HNCO, with MgCl2 having a minor effect on HNCO. Theoretical simulations revealed that the competitive effect of AAEMs on the formation paths of aromatic nitrogen compounds was the main reason for the overall change in the three nitrogen-containing gases.

Summary: This study investigates the influence of intrinsic alkali and alkaline earth metals (AAEMs) and organic matter chemical structure on char reactivity, providing evidence for the controversial role of water-soluble AAEMs during char gasification. Results show that water-soluble AAEMs decrease char reactivity in the early gasification stage due to catalytic cracking of aromatic C-H bonds, while increasing it later due to original catalysis; ion-exchangeable AAEMs catalyze the opening of aromatic rings in char, particularly small rings, weakening the reaction priority of aliphatic structures. Increasing pyrolysis temperature results in ordered chemical structure and enrichment of ion-exchangeable AAEMs, affecting char reactivity differently at different temperature ranges.

Summary: This paper investigates the influences of active alkali and alkaline earth metals (Ac-AAEMs) on the physicochemical properties of chars during co-pyrolysis-gasification coupling. The experimental results demonstrate that Ac-AAEMs, especially those in OCS, significantly promote the development of mesopores and catalyze the specific surface area of chars. Additionally, Ac-AAEMs contribute to the destruction of highly graphitized carbon structures and the formation of disordered amorphous carbon.

Summary: The research aims to elucidate the reaction mechanisms of BaFe2O4 with solid carbon (C) and carbon monoxide (CO) during chemical looping gasification process. It was found that BaFe2O4 is more active in solid-solid reaction while Fe2O3 performs better in solid-gas reaction. The study suggests that BaFe2O4 has potential in CLG process due to its stronger surface activity and weaker lattice oxygen migration ability compared to Fe2O3.

Summary: In this study, the structure and properties of DESs synthesized by different molar ratios of betaine and 1,2-propanediol were investigated using DFT and MD simulation. The results confirmed the importance of the relationship between betaine and 1,2-propanediol in the formation of stable DESs. The analysis of hydrogen bonds suggested that the electrostatic interaction between the oxygen atoms of betaine and hydrogen atoms from the hydroxyl groups of 1,2-propanediol played a major role in the stability of DESs. Additionally, increasing the content of 1,2-propanediol weakened the hydrogen bond between betaine and 1,2-propanediol, and strengthened the hydrogen bond between 1,2-propanediol molecules. The viscosity of DESs was mainly determined by the interaction between betaine and 1,2-propanediol.

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.
