Abstract

The softening temperature of coal pitch obtained by coal-tar distillation is investigated as a function of three parameters: the rate of tar heating; the temperature of isothermal holding; and the holding temperature. A model in the form of a regression equation satisfactorily describes the dependence of the pitch’s softening temperature on those parameters in tar distillation and may be used to predict the pitch characteristics.

煤沥青软化温度对煤焦油蒸馏条件的影响

摘要

研究了通过煤焦油蒸馏获得的煤沥青的软化温度作为三个参数的函数：焦油加热速率；等温保温温度；和保温温度。回归方程形式的模型令人满意地描述了沥青软化温度对焦油蒸馏中那些参数的依赖性，并可用于预测沥青特性。
