Dependence of the Softening Temperature of Coal Pitch on the Conditions of Coal-Tar Distillation
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 dependen...

Zusammenfassung: | 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. |
