Open publisher page 0 citations

Abstract

Diesel desulfurization by selective oxidation is studied here. The preliminary test result shows that the sulfide in diesel could be efficiently removed by using the method with hydrogenperoxide, trifluoroacetic acid, glacial acetic acid as oxidants. The sulfur content of straight-run diesel is reduced from 213.5 ppm to 21.92 ppm after being treated, and the desulfurization rate is normally up to 89.37%. The method is expected to provide a new route for clean diesel fuel production.
