Abstract
A study of the oxidative desulfurization of hydrogenation
diesel using air as oxidant, tert-butyl hydroperoxide (TBHP) as radical
initiator at ambient pressure and moderate temperature in the presence of
isobutyl aldehyde is described.
TBHP could accelerate the production of carbonyl radical and its
peroxidation. The sulfur content of the hydrogenation diesel could be reduced
from 403 to 13 ppm (96.8% removed) under the synergistic effect of air,
TBHP and isobutyl aldehyde.
