Catalytic Desulfurization of Heavy Oils and Hydrogen Sulfide Removal
This community develops chemical processes to strip sulfur compounds from crude oil, heavy fuel, and natural gas, primarily to meet environmental standards and improve fuel quality.
The work centers on oxidative desulfurization and hydrodesulfurization, using catalysts such as molybdenum, nickel, and activated carbon to remove sulfur from heavy crude and diesel. A significant portion of the research focuses on capturing hydrogen sulfide from gas streams and converting it into useful products. Solvents like ionic liquids and deep eutectic solvents are frequently tested for their ability to dissolve sulfur compounds efficiently. The papers describe specific reactor designs, catalyst synthesis methods, and the removal of dibenzothiophene and other refractory sulfur species from liquid fuels.
The largest share of the community's output is found in sulfur research, accounting for 2.5% of all sulfur research, and 7,359 papers here.
The community comprises 16,567 papers, publishing most frequently in Fuel, Journal of Catalysis, and Catalysis Today.
Recent papers continue to focus on developing photocatalysts for visible-light desulfurization, metal-organic frameworks for adsorptive removal, and new reactor designs for continuous processing of heavy gasoil.
