ADDITIVE FOR INCREASING OF THERMAL-OXIDATIVE STABILITY OF HYDROCARBON JET ENGINE FUEL AND JET ENGINE FUEL Russian patent published in 2009 - IPC C10L1/10 C10L1/18 C10L1/22 

FIELD: oil and gas production.

SUBSTANCE: invention relates to field of oil processing and petrochemistry. Additive for increasing of thermal-oxidative stability of hydrocarbon jet engine fuel on the basis of once-run kerosine distillate contains 2.2-methylene-bis(4-methyl-6-tert-butylphenol), oily solution of alkenylpyrrolidinedione, and bis-(3,5-di-tert-butyl-2-hydroxybenzal) ethylenediamine at following correlation of components, wt %: oily solution of alkenylpyrrolidinedione- 1-2, bis-(3,5-di-tert-butyl-2-hydroxybenzal) ethylenediamine - 1-2,2,2-methylene-bis(4-methyl-6-tert-butylphenol) - the rest. Jet engine fuel on the basis of once-run kerosine distillate additionally contains specified additive in amount 0.03-0.05 wt %.

EFFECT: creation of additive, increasing TOC of jet engine fuel on the basis of once-run kerosine distillate with keeping of its standard quality rating, that provides increasing of maximum permissible application temperature of fuel for 80-100°C and withdrawal into fuel additive during the process of manufacturing in plant conditions.
