Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. [1] The term usually refers to the removal of sulfur from a molecule or a material by hydrogenolysis: [2] R 2 S + 2 H 2 → 2RH + H 2 S. Hydrogen is the ultimate sulfur acceptor. As applied to oil refinery streams, the conversion is known as ...
Flue-gas desulfurization (FGD) ... This is an example of a radiation chemistry process [18] where the physical effects of radiation are used to process a substance.
Hydrodesulfurization or hydrodesulphurisation (Commonwealth English; see spelling differences) (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.
Claus was born in Kassel in the German State of Hesse in 1827, and studied chemistry in Marburg before he emigrated to England in 1852. He died in London in 1900. [7] His grave is in Margravine Cemetery, Hammersmith.
The 4S pathway is a sulfur-specific metabolic pathway of oxidative desulfurization that converts dibenzothiophene (DBT) into 2-hydroxybiphenyl and sulfite.It uses a total of four NADH molecules (three required by DszD to generate FMNH 2 and a fourth to regenerate the FMN-oxide byproduct of DszA) and three molecules of oxygen, thus producing NAD + and water as byproducts.
Raney nickel is used in organic synthesis for desulfurization. For example, thioacetals will be reduced to hydrocarbons in the last step of the Mozingo reduction: [14] [15] Example of desulfurization of thioacetals using Raney nickel. Thiols, [16] and sulfides [17] can be removed from aliphatic, aromatic, or heteroaromatic compounds.
Flue-gas desulfurization [ edit ] The SNOX process can be applied for treatment of flue gases from combustion of primarily high-sulfur fuels in power stations, refinery and other industrial boilers and for treatment of other waste gases containing sulfur compounds and nitrogen oxides.
