STABLE, READY TO USE CATALYTIC COMPOSITION FOR CLEANING OIL AND GAS CONDENSATE FROM HYDROGEN SULFIDE AND LIGHT MERCAPTANS Russian patent published in 2022 - IPC B01J23/04 B01J23/75 B01J23/882 B01J27/53 B01J27/08 B01J27/10 B01J27/18 B01J27/24 B01J27/32 B01J37/04 C10G27/10 

FIELD: oil and gas condensate purification.

SUBSTANCE: invention relates to methods for the oxidation-catalytic purification of oil and gas condensate from hydrogen sulfide and light mercaptans, in particular to the production of ready-to-use catalyst compositions for technologies for the purification of hydrocarbon feedstock from sulfur compounds used in the gas and oil industry. The catalytic composition contains 20-30 wt.% aqueous ammonia solution and a catalytic additive in the form of derivatives of cobalt phthalocyanine complexes. Derivatives of cobalt phthalocyanine complexes contain 0.05-5 wt.% halogen-substituted derivatives of cobalt phthalocyanine complexes of the general formula: [CoPC]Xn(SO₃)₂^2–2Cat+, where CoPC is a compound of the structural formula:

where R = R₁= H⁺, with n=1 or 3: X = Cl, Br; Cat⁺ = H⁺, Na⁺, K+, NH₄⁺; at n=2: X = Cl, Br; Cat⁺ = Na⁺, K+, NH₄⁺.

EFFECT: stable liquid composition for efficient cleaning in one stage of hydrocarbon feedstock with a high content of hydrogen sulfide of 500-600 ppm and light mercaptans with a content of up to 460 ppm, prepared directly from the manufacturer, as well as high activity of the composition due to the use of halogen-substituted cobalt phthalocyanine derivatives in the composition.
