Abstract ：
When the valuable metals in the hydrodesulphurisation (HDS) catalysts are recovered by the pyrometallurgical process, the traditional roasting method is prone to the problem of insufficient oxidative conversion of metal sulfides. However, the residual oil and carbon in the spent HDS catalysts cannot be effectively utilized, resulting in additional energy consumption. Fluidized roasting in a boiling furnace is a good way to use residual oil and carbon to provide heat for roasting while oxidizing the metal sulfides in the spent HDS catalyst. This study used computational fluid dynamics (CFD) coupled with the Coarse -Graining model (CGM) to simulate the fluidized roasting effect of HDS catalysts at different initial bed heights and gas velocities in a large-scale industrial boiling furnace. To improve the fluidized roasting quality and reduce the energy consumption, it is recommended that the optimal initial bed height ( H 0 ) is 0.45 m, the gas velocity ( u g ) is 1.45 m/s. The gas consumption and the net energy saving were 0.34 m 3 /kg and 2.29 x 10 10 J under this condition. Accordingly, the theory of the competitive relationship between particle collision and bubble fragmentation is innovatively proposed, and the distribution change of the turbulent energy intensity zone verifies this theory.

Abstract ：
Bromine resources, widely utilized in basic chemical engineering, are considered non-renewable. A substantial amount of Bromine-Rich Saline Wastewater (BRSW), a hazardous waste, is generated during the smelting process of waste printed circuit boards (WPCBs). The efficient conversion of bromine resources is important in BRSW, which contain high concentrations of bromide ions. This study developed a synergistic treatment method utilizing electrolytic manganese anode sludge (EMAS) achieved efficient conversion of Br- to Br-2 in BRSW. Optimal technical parameters are determined through single-factor experiments, and the oxidative acid leaching process was optimized using response surface methodology (RSM). The significant influencing factors for Br- conversion were ranked as acidity > anode mud addition amount > temperature > time, resulting in a bromine conversion efficiency of 96.55%. Kinetic studies of bromine conversion in BRSW during the oxidation-acid leaching process indicated a two-stage process: Stage I being a chemical reaction control model and Stage II being a diffusion control model. The reaction mechanism was elucidated, where H+ initially breaks the Mn-O bond in MnO2, exposing O vacancies and forming Mn4+, leading to a redox reaction between free Br- and Mn4+. This research embodies the concept of synergistic solid waste disposal, achieving cost-effectiveness and streamlined preparation of bromine, and providing technical and theoretical support for bromine resource recovery in BRSW.

Abstract ：
Spent hydrogenation catalysts (HDCs) contain many Mo, V, Co, Ni, and Al2O3 carriers, which are valuable secondary resources. However, improper disposal can also lead to environmental pollution risks. In the past decade, research reviews on the recovery of valuable metals from spent HDCs have been somewhat reported, mainly summarizing basic technical processes. Based on previous work, this article reviews the emerging recycling technologies of spent HDCs in recent years. The research trend of furnace optimization in the pyrometallurgical process was innovatively proposed, and the importance of developing new mild leaching agents for the high-quality recycling of Al2O3 carriers in the hydrometallurgical process was clarified.

Abstract ：
Biomass-synthesized biochar has abundant pore structure, large specific surface area, and strong adsorption capacity. Phase change materials (PCMs) have obvious advantages in using clean energy and improving energy efficiency. Biochar-based composite PCMs use the abundant pore structure of the biochar to efficiently encap-sulate PCMs, which not only achieve carbon sequestration but also have broad application prospects in the fields of solar energy usage, energy-saving buildings, and environmental temperature control. This review summarizes the synthesis of biochar and biochar-based composite PCMs in detail, as well as their application. Importantly, the prospect of biochar-based composite PCMs development is presented. This review will provide references for advancing the study of biochar-based composite PCMs, which are crucial for resource recycling, as well as green and low-carbon development.
