Abstract:

Different processes for modified pitch production,both at home and abroad,are introduced in this paper,in particular,the continuous production process for modified pitch by tubular furnace method under negative pressure,which has been put into commercial production at present.This process is characterized with low reaction temperature,long operation period,low energy consumption,environment-friendly production and stable operation,which is applicable to medium temperature pitch feedstock with low QI.

Key words:

"> Modified pitch, Tubular furnace, Continuous production, Negative pressure
