In this paper, coal-tar pitch is modified with divinylbenzene (DVB) in the presence of p-toluene sulfonic (PTS) acid. Carbonization behavior of the modified coal-tar pitch and optical texture of resultant semi-cokes are studied. The carbonization behavior is studied by thermogravimetric analysis (TG

This study examines the effect of pitch concentration, rate of heating, soak temperature and time of soak upon the optical texture of cokes prepared from the co-carbonizations of a coal (Oxcroft-Clowne, NC6 Rank 802) and three vitrains of NCB Rank 204,801,902 with Ashland A240 petroleum pitch. Using
