METHOD FOR DEWAXING DIESEL FUEL Russian patent published in 2024 - IPC C10G73/36 C10G73/28 C10G73/32 

FIELD: fuel industry.

SUBSTANCE: invention relates to methods for dewaxing oil products, in particular to a method for dewaxing diesel fuels, as well as methods for dewaxing oils, deoiling paraffins and fractionating them. Described is a method for dewaxing diesel fuel of a weighted fractional composition by centrifugation to obtain summer diesel fuel, where initial diesel fuel is mixed with pigment aluminum powder at its content in fuel from 0.1 to 3.0 wt.% and subjected to thermal treatment at temperature higher than temperature of paraffin dissolution in fuel, cooled to dewaxing temperature, centrifuged at temperature from minus 5 to minus 20 °C for 2.5–30 minutes and relative centrifugal acceleration of centrifuge 12,108 g, where g=9.81 m/s², to obtain summer diesel fuel that meets GOST 32511–2013.

EFFECT: increasing output of dewaxed diesel fuel with improved low-temperature properties and obtaining at optimum parameters of the process of centrifugation of "C" summer diesel fuel, which corresponds to GOST 32511–2013.
