METHOD FOR PRODUCING ISOTROPIC OIL COKE ON THE BASIS OF SHALE-OIL
摘要
The invention is provided for producing oil coke on the basis of shale oil. The raw material is inserted in the coke cube, after which the thermo-oxidation and coking of the raw material are performed. Further the obtained oil coke is heated and after that annealed. The thermo-oxidation is performed at a temperature of 270-290 °C and terminated when the softening point of the raw material having been determined by the ball and ring method is 100-140 °C. The vaporised fractions emerged and the air used for thermo-oxidation are processed and re-utilized.
