Desulfurization - Wikipedia
Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule (e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as oil refinery streams. [1]

A fast and environment-friendly method for preparing …
2023年12月15日 · Here we demonstrate a solution route through direct electro- desulfidation solid MoS 2 at 973 K in LiCl melt with a fast and environment-friendly method. When the scan rate was 50 mV/s, the total reduction (0.5 mg MoS 2 in the MCE.) time was less 16 s, and the peak current density was as high as 38 A/cm 2 with reference to the geometric surface ...
Quadruple sulfur isotopic fractionation during pyrite desulfidation …
2020年3月15日 · In this study, we experimentally simulated the formation of pyrrhotite through desulfidation of pyrite, and chemical vapor deposition (CVD) of released sulfur onto iron metal and reaction thereof to form pyrrhotite. Selection of appropriate starting pyrite isotope compositions allows us to trace the sulfur through the various reactions.
