Summary: By regulating the Bronsted acid sites on supports, the activity of supported Fe catalysts in hydrodesulfurization can be enhanced, leading to improved dispersion of active metal species and catalytic activity. Additionally, the presence of an appropriate B acid site density can reduce support and metal site interactions, lower reduction temperature, and promote sulfidation of the catalysts. Furthermore, catalysts with B acid sites can improve product selectivity by facilitating direct desulfurization and isomerization routes during HDS.

Summary: The research focused on the activity of catalysts in the reactions of model compounds and their mutual influence. It was found that quinoline can promote the hydrodesulfurization reaction of DBT as a source of hydrogen at 260 degrees C. The possibility of intermolecular hydrogen transfer reactions in the reactions of tetrahydroquinoline and DBT was also demonstrated.

Summary: This paper investigates the mechanism of electrochemically induced carbon-bromine dissociation in 1-Br-2-methylnaphalene under reduction conditions. Quantum mechanical calculations reveal that the dissociation of the carbon-halogen bond occurs in a stepwise manner, leading to the formation of a bromide anion and an organic radical.

Summary: This study successfully prepared a novel and effective bifunctional heterogeneous catalytic system for the desulfurization process by synthesizing nanorod-OMS-2 and molybdenum oxide catalysts. By controlling the composition and structure of the catalysts, highly dispersed molybdenum oxide species and strong acidic sites were achieved, resulting in improved catalytic activity and stability. The kinetics of the desulfurization reaction and the optimum conditions were investigated, providing a basis for further optimization of catalyst design.

Summary: A core-shell porous catalyst coated with TiO2-fibrous silica (KCC-1) was prepared and showed excellent catalytic desulfurization performance. The unit desulfurization rate was significantly improved without additional oxidants. The adsorption-catalysis-resorption desulfurization system was effective, enhancing the reaction rate and achieving selective adsorption and coupling desulfurization. Furthermore, the spent catalyst could be regenerated without a decrease in desulfurization rate.
