Hydrodesulfurization (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.
1 de jul. de 2023 · Sulfur removal was only 5% using a relative humidity of 41%. Results indicated that excessive water content (more than 19% relative humidity in this research) can form a thin film on the adsorbent surface as well as pore blockage, avoiding the diffusion of H 2 S onto the adsorbent.
1 de dic. de 2022 · The removal of sulfur compounds (S-compounds) found in transportation fuel and other petroleum products is necessary and has drawn tremendous attention of both oil exporting and importing countries. The combustion of fuel oil leads to the production of hazardous materials including sulfur-containing compounds which are unfriendly to ...
Hydrotreating is a set of operations that react crude oil cuts with hydrogen and a catalyst to produce desulfurized fuels. Learn the basics of hydrotreating, the types of catalysts, the importance of hydrogen, and the environmental benefits of hydrotreating.
22 de mar. de 2017 · There are four stages where sulphur can be removed: in the blast furnace (BF), during hot metal (HM) pretreatment, in the converter and during the secondary metallurgy (SM) treatment. For sulphur removal a low oxygen activity and a basic slag are required.
Learn how sulfur is removed and recovered from petroleum, natural gas and other fossil fuels to protect the environment and produce useful chemicals. The chapter covers sulfur chemistry, sources, analysis, processing and applications.
The research efforts for developing conventional hydrodesulfurization and alternative desulfurization methods such as selective adsorption, biodesulfurization, oxidation / extraction (oxidative desulfurization), etc. for removing these refractory sulfur compounds from petroleum products are on the rise.
