COKE REINFORCED WITH CARBON FIBRE, OBTAINED ON RETARDED COKING INSTALLATION Russian patent published in 2009 - IPC C04B35/52 C04B35/532 C10B55/00 C25B11/12 

FIELD: chemistry.

SUBSTANCE: coke is formed with combined coking of mixture of small amount of cut carbon fibres and heavy residues of oil or coal tar and pitch processing, obtained by mixing carbon fibres or stabilised precursor fibres for formation of carbon fibres with flow of supplied raw material for method of retarded coking, coking of said mixture on known retarded coking installation and burning of obtained coke. Raw material consists of group of residues with high content of aromatic compounds after distillation in vacuum, light cracking, catalytic cracking in pseudoliquified layer, thermal cracking, pyrolysis of ethylene or soft pitches, produced by coal coking or distillation of coal residues with high content of aromatic compounds. Coke is applied in polygranulated amorphous or graphitised carbon materials, containing at least 70% wt, of carbon, in particular, in coal electrodes and in connected with them connecting elements (nipples), fine-grained graphites and reactor graphites, in bricks for blast furnaces or cathodes and anodes for electrolysis of melted aluminium salts.

EFFECT: obtaining reinforced with carbon fibres coke of high quality from residues of oil processing.
