As the QI content in coal tar and pitch of Meishan branch appears lower than normal,this paper introduced a solution that a blended oil and/ or the coal tar with high QI content bought from outside the company are used to increase the QI content in the pitch. This blended oil can be used to produce medium-temperature pitch and modified pitch so that the ratio of first - grade products can be increased due to the improved QI content.
