USE OF HEAVY DARK OIL COMPONENTS AS CATALYST IN OXIDATIVE PURIFICATION OF HYDROCARBON COMPOSITIONS FROM HYDROGEN SULPHIDE AND LIGHT MERCAPTANS, CATALYST BASED OF HEAVY DARK OIL COMPONENTS FROM HYDROGEN SULPHIDE AND LIGHT MERCAPTANS
USE OF HEAVY DARK OIL COMPONENTS AS CATALYST IN OXIDATIVE PURIFICATION OF HYDROCARBON COMPOSITIONS FROM HYDROGEN SULPHIDE AND LIGHT MERCAPTANS, CATALYST BASED OF HEAVY DARK OIL COMPONENTS FROM HYDROGEN SULPHIDE AND LIGHT MERCAPTANS
Use of heavy dark components of oil, whose residue after distillation of fractions boiling out under 350 deg.C. contains copper and vanadium total not less than 0.005 mass % counted on pure metal, as a catalyst during oxidative purification of hydrocarbon compositions from hydrogen sulphide and light mercaptans. The catalyst is selected from heavy dark components of oil. A method of purification of hydrocarbon compositions from hydrogen sulphide and light mercaptans by its oxidation with air oxygen or oxygen-containing gas at temperatures from 55 deg.C. to 135 deg.C. in presence, as a catalyst, of heavy dark components of oil, whose residue after distillation of fractions boiling out up to 350 deg.C. contains copper and vanadium total not less than 0.005 mass % counted on pure metal.
