OXYGEN-CONTAINING COMPOSITE DIESEL FUEL Russian patent published in 2024 - IPC C10L1/04 C10L1/185 

FIELD: fuel industry.

SUBSTANCE: invention relates to oxygen-containing composite diesel fuel containing 0.05 to 20 wt.% paraldehyde, remaining liquid petroleum fuel for use in engines with ignition of fuel-air mixture from compression, obtained during processing of oil and gas condensates, or mixture of liquid petroleum fuel for use in engines with ignition of fuel-air mixture from compression, obtained during processing of oil and gas condensates, with base biodiesel fuel—up to 100 wt.%.

EFFECT: invention provides the development of composite diesel fuel for compression ignition engines (diesel engines), provides the use of renewable components, provides the use of components having a wide resource base, ensures the elimination of the content of components that are readily soluble in water and poorly soluble in petroleum diesel fuel, provides use of paraldehyde, provides creation of additive to composite diesel fuel, completely consisting of renewable components, provides exclusion of components with boiling point and viscosity lower than that of paraldehyde, which lead to reduction of flash point and viscosity of diesel fuels, increased wear of fuel equipment, provides elimination of content of glycerides of unsaturated fatty acids, leading to coking of engines, leading to frequent change of engine oil, provides elimination of content of polycyclic hydrocarbons, which reduce cetane number and increase opacity of diesel fuel, provides use of unsaturated hydrocarbon gas, which sharply reduces technical applicability of fuel.
