FIELD: technological processes.
SUBSTANCE: invention relates to oil refining, in particular, to methods of hydrogen-free reduction of sulfur content in vacuum gas oil, as well as to composition of catalyst for oxidation reaction of sulfur compounds contained in vacuum gas oil. Disclosed is a catalyst for oxidative desulphurisation of vacuum gas oil of the following composition (wt%): concentrated formic acid 80±5, water 13±5, compound containing molybdenum, or tungsten, or vanadium 4±1, Neonol AF 9–6 or N-oxide of amine 2±0.5, tetrabutylammonium bromide or tetraoctylammonium bromide 1±0.1.
EFFECT: high degree of removal of sulfur from vacuum gas oil with high selectivity, which enables to minimize negative impact on hydrocarbon composition of raw material.
