Abstract: The paper introduced six coal tar processing techniques operated in China, analyzed the advantages and disadvantages of each technique and pointed out the problems existed in the domestic traditional one tower coal tar processing technique. Based on the circumstances, the asphalt produced with the constant pressu re continued thermal polymerization method of coal tar could meet the requirements of the domestic carbon industry.From a view of the long development, the French at mospheric and vacuum distillation technique to produce the no sodium ion asphalt and the USA tower bottom circulated pressure reduced and vacuum distillation techni que to produce non mesophase asphalt would be the development orientation of the future coal tar processing.
