FIELD: chemistry.
SUBSTANCE: invention relates to a method of removing hydrogen sulphide and mercaptants from oil and gas condensate by treating starting material with 5-30% aqueous solution of hydrogen peroxide, taken in amount of 3-8 kg per ton of the material, at temperature 10-30°C and pressure of up to 1.5 MPa, in the presence of a catalyst, characterised by that the catalyst used is bis-sulphoxides of molybdenum peroxocomplexes, where the catalyst is taken in amount of 0.01-0.05 g per ton of oil or gas condensate and is added to the material inform of a solution in aqueous solution of hydrogen peroxide.
EFFECT: avoiding use of expensive and scarce activating additives, less amount of the catalyst used, high degree of purity of material from hydrogen sulphide and mercaptants.
