METHOD FOR ULTRASOUND-ASSISTED OXIDATIVE DESULFURIZATION OF FOSSIL FUELS

摘要

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.;32 cl, 4 dwg, 15 tbl, 7 ex
