Desulfurization mechanism of an excellent Cu/ZnO sorbent for ultra-deep removal of thiophene in simulated coke oven gas

Fanjing Wei et al.

Summary: The reactive adsorption desulfurization mechanism of thiophene over Cu/ZnO sorbent in coke oven gas (COG) was established by combining theoretical and experimental studies. The study found that Cu-0 nanoparticles in the sorbent play important roles in hydrogen adsorption and dissociation as well as cleaving the C-S bond of thiophene. ZnO in the sorbent acts as an excellent sulfur acceptor and greatly affects the adsorption properties by enhancing the spillover and storage of hydrogen atoms. Enhancing the interaction between Cu0 nanoparticles and ZnO is an effective way to improve the thiophene reactive adsorption activity of Cu/ZnO.

Mesoporous sulfur-decorated Pt-Al2O3 for dehydrogenation of perhydro benzyltoluenes: Activity-favorable adsorption of reaction species onto electron-deficient Pt atoms

Yeongin Jo et al.

Summary: The addition of sulfur to supported Pt catalysts has an impact on Pt defect sites and side reactions, which is influenced by the catalyst preparation methods. In this study, mesoporous sulfur-decorated Pt-Al2O3 catalysts with different sulfur contents were prepared using the solvent-deficient precipitation (SDP) method. The dehydrogenation of perhydro benzyltoluenes showed a volcano-shaped dependence on the sulfur content, with the maximum dehydrogenation achieved at 0.21 wt% sulfur. The best performing catalyst exhibited excellent recyclability due to negligible Pt growth and sulfur loss. The SDP method facilitated favorable contact between Pt and sulfur species, resulting in a reduction in electron density of Pt atoms. This electron-deficient Pt atoms weakened the adsorption of aromatic products and facilitated appropriate H-2 adsorption. As a result, the titled catalyst exhibited tolerance towards dehydrogenation products and lower selectivity towards the side product methylfluorene.

Mechanism of Dibenzofuran Hydrodeoxygenation on the Surface of Pt (111): A DFT Study

Xing-Bao Wang et al.

Summary: This study investigates the mechanism of dibenzofuran hydrodeoxygenation on the Pt(111) surface using density functional theory calculations. The results show that the five-membered-ring opening of tetrahydrodibenzofuran is easier than that of hexahydrodibenzofuran, leading to the formation of 2-cyclohexylphenol through a nonconsecutive hydrogenation pathway and multiple radical species. The investigation suggests that the target product bicyclohexane is most likely formed through a radical intermediate during the hydrodeoxygenation of dibenzofuran on the Pt(111) surface, providing valuable theoretical guidance for designing new catalysts in coal to liquid hydrodeoxygenation.

Steric Hindrance of Methyl Group on the Reaction Pathway of Hydrodesulfurization in the Presence of Quinoline

Xilong Chen et al.

Summary: The study found that the presence of quinoline and steric hindrance of methyl can alter the hydrodesulfurization pathway and exacerbate the transformation process. Quinoline has a relatively mild poisoning effect on DBT HDS, but when adjacent methyl is present, the inhibition on 4,6-DMDBT HDS is still significant. Additionally, quinoline affects the ratio of HYD/DDS pathway yield, increasing the production of HYD products.
