FIELD: petroleum chemistry. SUBSTANCE: hydraulic desulfurization performed in distillation column-type reactor having evaporation section and rectifying section includes the following stages: delivery of hydrocarbon flow at boiling-out limits of naphtha including organic sulfur-containing compounds and hydrogen to distillation column-type reactor above evaporating section; separation of naphtha into light and heavy fractions in distillation column-type reactor; bringing heavy naphtha in contact with catalyst of hydraulic desulfurization in evaporating section for selective interaction of heavier organic sulfur- containing compound with hydrogen so that H2S is formed; removal of light fraction of naphtha, H2S and unreacted hydrogen from distillation column-type reactor as overhead products; removal of heavier fraction of naphtha from distillation column-type reactor as sediments. According to other variants, use may be made of additional single-pass reactor with movable layer containing catalyst of hydraulic desulfurization for interaction of heavier organic sulfur-containing compounds with hydrogen and forming H2S. EFFECT: enhanced efficiency. 14 cl, 11 dwg, 1tbl, 1 ex
