Summary: Nickel oxide was loaded onto activated carbon to improve the adsorption selectivity in desulfurization of model diesel. The incorporation of NiO significantly enhanced interactions between thiophenic compounds while mitigating competitive interactions between more steric compounds. The improved performance was attributed to increased Lewis acidity and Ni-S acid-base interactions caused by loading NiO on activated carbon.

Summary: The study focuses on the sulfur removal from tire pyrolysis oil (TPO) by distillation and oxidation desulfurization process (ODS). A fraction of TPO with boiling point range of 190-350 °C, designated as TPO190-350 °C, was obtained by distillation. The sulfides in TPO190-350 °C were mainly benzothiophene derivatives. A POM-based catalyst was used in the ODS process to remove sulfur compounds from the oil, and it showed excellent catalytic performance and recyclability. The desulfurization efficiency of TPO190-350 °C was achieved up to 91.28%, reducing the initial sulfur contents from 11033 ppm to 961 ppm.

Summary: Sulfur dioxide emissions from fossil fuel combustion can have negative impacts on health and the environment. The current hydrodesulfurization method used by refineries has limitations in producing ultralow sulfur diesel at reasonable costs. Ionic liquids have been explored as potential alternatives, but there is limited research on their industrial-scale feasibility and integration into process simulators. This study screened and evaluated 26 commercially available ILs for desulfurization of diesel fuel using COSMO-based models and Aspen Plus, and proposed an optimized process using 1-butyl-3-methylimidazolium thiocyanate that achieves ULSD with minimal loss of the IL.

Summary: The Keggin-type heteropoly acids H3PMo12O40 and H3PW12O40 supported on activated carbon demonstrated high catalytic activity for oxidative desulfurization of model diesel fuel, influenced by the basicity of the carbon support. These catalysts, particularly the decomposed H3PW12O40, outperformed other heterogeneous catalysts for ODS by efficiently removing DBT from the fuel with high H2O2 efficiency and the ability to be recovered and reused without loss of activity. Additionally, DRIFTS studies provided insight into the mechanism of ODS reaction on carbon-supported HPAs.

Summary: A 3D assembly TiO2 nanoflower catalyst with controllable oxygen vacancies was developed for oxidative desulfurization (ODS) in diesel oil. The increased oxygen vacancies and Ti3+ promote the chemical adsorption and reduce the energy barriers, leading to the generation of hydroxyl radicals and superoxide radicals. The experiment showed a 100% ODS rate in only 30 minutes under optimal conditions.

Summary: Desulfurization of liquid fuels is essential to reduce the emission of sulfur oxides and particulates during fuel combustion. In this study, the desorption mechanism of sulfur from neutral activated alumina saturated with dibenzothiophene sulfone was investigated, with batch experiments showing that acetone had superior desorption efficiency compared to other eluents. The desorption kinetics followed a pseudo-second-order equation with chemisorption as the rate-determining step, and thermodynamics study revealed the spontaneous and endothermic nature of sulfur desorption using acetone as eluent. Overall, neutral activated alumina was proven to be an efficient and reusable adsorbent for sulfur compound removal from liquid fossil fuels.

Summary: This study examined the improvement of air quality in a fitness center's exercise room under normal operating conditions, focusing on bacterial and fungal contamination. Chlorine dioxide and weak acid hypochlorous water aerosols were found to be more effective in removing bacteria and fungi than water scrubbing, with a 15-minute contact time sufficient to meet air quality standards. User density and carbon dioxide levels had a significant impact on the disinfection performance of bacteria and fungi, while temperature specifically affected fungi disinfection.

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.
