Summary: In this article, a series of effective catalysts based on betaine and sulfuric or phosphomolybdic acids were obtained. These compositions were characterized and tested in the oxidation of sulfur- and nitrogenous-containing compounds by H2O2. The acidity change is non-linearly influenced by the amount of heteropolyacid (HPA), and the removal of sulfur-containing compounds is correlated with the concentration of Bronsted acid sites on the catalyst surface. On the other hand, the removal of pyridine is primarily determined by the content of heteropolyacids in the catalyst.

Summary: Extractive desulfurization using ionic liquids has attracted attention due to its simplicity and easy operating conditions. However, the selection of suitable cations and anions remains a challenge. This study developed a methodology to screen cation and anion molecules for maximum sulfur removal efficiency. Through genetic algorithm and principal component analysis, it was determined that certain imidazolium and pyridinium cations combined with specific anions are promising for extractive desulfurization. The selected ionic liquid, [HMPY][N(CN)2], was synthesized and evaluated, showing potential as a solvent for removing DBT or BT from n-heptane.

Summary: The increasing energy consumption has led to a rise in sulfur emissions, causing economic and health issues, as well as impacting the efficiency of diesel engine emission control systems. To combat this, research is being conducted on various desulfurization technologies, including conventional methods like hydrodesulfurization and alternative processes such as adsorptive, extractive, oxidative, and bio-desulfurization. Factors such as DES selection, extraction temperature, extraction time, DES regeneration, and multistage extractions play a crucial role in the desulfurization efficiency, with deep eutectic solvents showing promise as a less toxic and more efficient alternative for extractive desulfurization.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
