Abstract:The pyrolysis condensation of zirconium-containing pitch was studied by means of TG/ DTG and was
compared to pitch. Results show that the pyrogenation reaction of pitch contain zirconium was similar to baselinepitch,
but initial pyrolysis temperature of zirconium-containing pitch was higher than baseline-pitch and viscosity was
greater. The initial pyrolysis temperature Ti and final pyrolysis temperature Tm increased with increasing the heating
rate and the peak of DTG curve became acute and moves to the high temperature orientation. The activation energy of
zirconium-containing pitch and based-pitch is close, which indicated that the reactive activity had no obvious change
under the current content of zirconium.
