Oxidative Desulfurization Using Polyoxometalates
Abstract
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 [W 6 O 19 ] 2-, [V(VW 11 )O 40 ] 4-, [PVW 11 O 40 ] 4-, and [PV 2 Mo 10 O 40 ] 4- were prepared, and their activities were compared with (VO) 2 P 2 O 7 . The experimental results show that the highest active catalyst is [V(VW 11 )O 40 ] 4- . The method was also used for the treatment of gas oil. The combination of solvent extraction and alumina adsorption can efficiently separate sulfone products. The resulting oil contained less than 0.055% sulfur, and this corresponds to 90 % removal.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
