Determination of Pyrolysis Characteristics and Kinetics of Pinus sylvestris var. mongolica Using TGA FTIR and Distributed Activation Energy Model

In order to get a fundamental understanding of pyrolysis behavior and kinetics of Pinus sylvestris var. mongolica, the TGA-FTIR instrument and distributed activation energy model （DAEM） via different heating rates (5,10,20,30 ℃/min）was taken for the study. The TG and DTG curves demonstrated that the pyrolysis process of PS consisted of the drying stage， degradation stage and carbonization stage. According to the FTIR analysis， the prominent volatile components generated by the pyrolysis of PS were CO2， aldehydes， ketones， organic acids， and alkanes， phenols etc. The fluctuation of activation energy can be interpreted as a result complex reaction occurred in pyrolysis process.
