Abstract

Coal tar pitch (CTP) as carbon material was studied using 1,4-Benzenedimethanol (PXG) as modifier by p-toluene sulfonic acid (PTS) catalyst and the variety of rheological properties of modified coal tar pitch (MTP) was discussed. The apparent viscosity of CTP and MTP were measured using rotating coaxial-cylinder viscometer, and the relations between the apparent viscosity and temperature were studied. Thermal behaviors of CTP and MTP were analyzed with TG-DSC. The results showed that the viscosity of the MTP gradually decreased with the temperature rising and the viscous activation energy of the MTP is 72.92 kJ·mol-1, which was beneficial to the process for producing carbon materials and the carbon yield was greatly improved. Therefore, coal tar pitch modified with PXG was qualified to be an excellent carbon precursor.
