Acceleration of production process for petroleum pitch
- 20 Downloads
An accelerated method has been developed for producing petroleum pitch. It has been shown that the thermocondensation of the raw material at temperatures of 460–500°C, with subsequent distillation of the volatile fractions, will reduce the required time for pitch production by a factor ranging from 5 to 20, in comparison with the time required under conventional conditions (400–420°C).
The introduction of the proposed method for pitch production is feasible in existing thermal-cracking units after appropriate reconstruction.
