METHOD OF PRODUCING HIGHLY STRUCTURED PETROLEUM COKE Russian patent published in 2024 - IPC C10B55/00 C10B57/16 C10G9/14 C10G57/00 

FIELD: oil refining.

SUBSTANCE: invention relates to the field of oil refining, in particular to a method of producing high-structured needle coke and anode coke. Method includes supply of initial raw material into column for preliminary preparation of secondary raw material at pressure of 0.4–2.0 MPa, removal of secondary raw material from the cube of column for preliminary preparation of raw material, and heating of secondary raw material in furnace. Then, the secondary raw materials are fed into the coke chambers, coked to produce coke, as well as with the coking gas and coking distillate removal, which are supplied to the lower part of the raw material preliminary treatment column, and feeding steam-gas products from the top of the column for preliminary treatment of raw materials through a pressure control valve into the fractionation column for fractionation.

EFFECT: increasing output of highly structured needle coke and anode coke, and reducing content of sulphur in produced coke.
