| Abstract: | Based on the traditional processing technology (batch distillation) of coal tar, some technical improvements has been made on the height of the distillation tower, the heating method of the distillation kettle and the processing conditions for the modified pitch. The operation temperature is decreased and the caking at the kettle bottom relieved due to the negative pressure distillation method. Additionally, the pollution from water and gas is properly controlled, thus, suggesting a unique small scale tar processing technology. The product is stable in quality and lives up to the standard. |
