FUEL COMPOSITION FOR DIESEL ENGINES Russian patent published in 2016 - IPC C10L1/23 C10L10/00 C10L1/18 C10L10/12 C07C201/02 C07C203/02 

FIELD: chemistry.

SUBSTANCE: invention describes a fuel composition for diesel engines, characterised by that, fuel additive used is a mixture of 10-25 wt% of a mixture of alkyl nitrates of alcohols C₆-C₉, 10-25 wt% of a mixture of dialkyl ethers based on alcohols C₆-C₉ and up to 100 wt% of diesel fuel or any hydrocarbon solvent, wherein initial alcohols C₆-C₉ to produce a mixture of alkyl nitrates and a mixture of dialkyl ethers used is a fraction of alcohols C₆-C₉, produced by liquid-phase oxidation of a fraction of n-alkanes C₆-C₉ with aqueous hydrogen peroxide solution in a medium of methanol on a heterogeneous catalyst DP-2, and subsequent hydrogenation of reaction mass on a rigid cellular catalyst Pd/Al₂O₃. Also disclosed is a diesel fuel containing said additive in amount of 0.01-0.5 wt%.

EFFECT: composition increases cetane number of diesel fuels by 4-6 units and lowers chilling point of diesel fuels by 10-15 °C.
