Abstract

The results presented herein were obtained by the scientists from Kazakhstan in research areas concerning the manufacture of carbon fibres by means of electrospinning from coal tar pitch and polyacrylonitrile, making coke from heavy oil residues, investigation of the composition and structures of asphaltenes extracted from the natural bitumen of the Munayly-Mola deposit. The precursor for carbon fibres was coal tar, a by-product of the treatment of coal from the Shubarkol deposit. The physicochemical characteristics and the composition of coke obtained from goudron at the Pavlodar petrochemical plant as a result of preliminary demetallization and desulphuration are demonstrated. It is established that the structure of asphaltenes from natural bitumen is more ordered and non-amorphous.
