FIELD: gas; oil refining and petrochemical industries.
SUBSTANCE: invention is related to the oxidative-catalytic regeneration of an alkaline agent saturated with mercaptides, formed as a result of desulfurization of liquefied hydrocarbon gases, in the presence of a heterogeneous catalyst for the oxidation of sulphur compounds, while an alkali aqueous solution containing alkanolamines in an amount of 0.1 to 2.5 wt.% is used as an alkaline agent.
EFFECT: reduction in the total sulphur content in purified liquefied hydrocarbon gas to no more than 0.001 wt.%.
