## Two procedures to prepare mesophase pitch from naphthalene using HF/BF, are described. The first procedure heats naphthalene at 80ยฐC with HFIBF, to give a naphthene rich pitch followed by either (a) heat treatment at 400-480ยฐC under vacuum (0.1 kPa) or (b) Heat treatment at 2.1 MPa followed by

The preparation of mesophase pitch as a precursor for the high-performance carbon fiber from a vacuum residue of FCC-decant oil (FCC-DOVR) was studied, applying a two-stage heat treatment to improve the pitch yield as well as its liquid crystal properties. The present two-stage preparation consisted
