摘要

Distillation of coal tar in an ARN-LAB-03 system yields 9% of a light oil fraction (boiling up to 170°C), 12% of a medium oil fraction (boiling at 170–230°C), 10% of a heavy oil fraction (boiling at 230–270°C), 32% of an anthracene fraction (boiling at 270–360°C), and 35% of a solid pitch residue. The anthracene fraction is subjected to coking. After coking the anthracene fraction for 5.5 h under a pressure of 3.5 MPa at 500°C, the yield of coke sample K-3 is 45%. The yield of coke sample K-4 obtained in the same conditions, but at 4.5 MPa, is 50%. On that basis, an effective method is proposed for producing coke from the anthracene fraction of coal tar.
