Study on Thermogravimetry and Pyrolysis Dynamics of Tung Oil

Abstract:

In this paper, Tung oil from the south of Shaanxi province was assayed, and the behavior of its thermal decomposition was investigated by thermogravimetry. The pyrolysis characteristics of Tung oil experimentally studied using thermo-gravimetric analyzer (TGA).The TG curves and DTG curves were examined under different operating conditions such as heating rate and different atmospheres. The mechanism equation of pyrolysis reaction, activation energy (E) and frequency factor (A) were obtained by using differential method to fit experimental data. The experimental results shown that there are two temperature ranges in the organic matter pyrolysis period: 350-420°C and 420-500°C in air, but 350-450°C in nitrogen. The effects on Tung oil pyrolysis of different heating rates were indistinct. The activation energy in the first period was more than that in the second period.
