Oxidative Desulfurization Using Polyoxometalates

Industrial & Engineering Chemistry Research, 2006
Oxidative desulfurization of model compounds (benzothiophene, dibenzothiophene, 4,6-dimethyldibenzothiophene) with hydrogen peroxide/acetic acid using polyoxometalates as catalysts has been studied. The tetrabutylammonium salts of [W6O19]2-, [V(VW11)O40]4-, [PVW11O40]4-, and [PV2Mo10O40]4- were prepared, and their activities were compared with (VO ...

Superoxides: Alternative Oxidants for the Oxidative Desulfurization Process

Energy & Fuels, 2008
Superoxides, for instance, potassium superoxide, have been demonstrated as alternative oxidants for the oxidative desulfurization process. For model compounds of benzothiophene, dibenzothiophene, and a number of selected diesel oil samples, sulfur removal greater than 90% and as high as 99% was accomplished.

Rare-Earth Oxide Desulfurizers

2017
The IGCC coarse gas derived from coal gasification process usually contains large amounts of sulfur containing components, such as H2S, COS, and CS2, 90% of them are H2S (~0.1 to 1.5 vol.%) which could cause severe corrosion of the pipelines, facilities, and catalysts in the subsequent coal gas conversion process; thus, the sulfur compounds need to be ...
