METHOD FOR ULTRASOUND-ASSISTED OXIDATIVE DESULFURIZATION OF FOSSIL FUELS Russian patent published in 2004 - IPC

Abstract RU 2235754 C1

FIELD: petroleum processing.

SUBSTANCE: method comprises following stages: combining fuel with acidified aqueous hydrogen peroxide-containing solution to form multiphase reaction milieu during a period of time long enough for oxidation of sulfides in fuel into sulfones; and extracting the latter to provide essentially sulfone-free organic phase.

EFFECT: increased sulfur removal efficiency.
