Effect of Two Kinds of Petroleum Residue on the Preparation of Mesophase Pitch

Mesophase pitch was prepared by atmospheric carbonization in liquid phase, and melting method was employed to test its properties in spinning. The effects of different ratios of cracking gasoline residue and heavy diesel oil from catalytic cracking on formation rate of mesophase pitch, yield, content of mesophase, microscopic structrue and spinning properties were studied. The best ratio has been derived.
