Description:
It has been widely discussed that desulfurization of dibenzothiophene and substituted dibenzothiophenes occurs through two reaction pathways, the direct sulfur abstraction route and the hydrogenation-abstraction route. The former involves adsorption of the molecule on the catalyst surface via the sulfur atom followed by C-S bond scission. This is the primary pathway over cobalt-molybdenum (CoMo) based hydrotreating catalysts. The second pathway involves saturation of one aromatic ring of the dibenzothiophene species followed by the extraction of the sulfur atom. Nickel-molybdenum (NiMo) catalysts have a higher activity for desulfurization via this route.
