Study on the Pyrolysis Kinetics Characteristics of the Wood from the Ancient Buildings

Abstract:

The pyrolysis kinetics properties of three kinds of woods, pinus koraiensis, hemlock and spruce, which were taken from the ancient building, the Potala Palace in Lhasa of China, were investigated by using thermogravimetric analysis method. And the Kissinger method was applied to calculate the degradation activation energy of the lignin of these three kinds of wood. The degradation activation energy of the lignin in pinus koraiensis, hemlock and spruce woods was 218kJ/mol, 146kJ/mol and 188kJ/mol, respectively, which showed that the degradation order from hard to easy for these three kinds of wood was pinus koraiensis, spruce and hemlock.
