Abstract

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.

煤焦油蒽馏分制焦炭

在ARN-LAB-03系统中蒸馏煤焦油可产生9%的轻油馏分（沸点高达170°C）， 12%的中油馏分（沸点在170 - 230°C）， 10%的重油馏分（沸点在230-270°C）， 32%的蒽馏分（沸点在270-360°C）和35%的固体沥青残渣。蒽部分经过焦化处理。在500℃条件下，在3.5 MPa压力下焦化5.5 h后，焦炭样品K-3的产率为45%。在相同条件下，在4.5 MPa下得到的焦炭样品K-4的产率为50%。在此基础上，提出了一种从煤焦油的蒽馏分制取焦炭的有效方法。
