Abstract

Weight losses in the thermal decomposition of the decomposed woods have been studied by means of dynamic experiments, carried out under argon atmosphere. The thermal pyrolysis of decomposed woods has been studied from ambient temperature up to 10000C by thermogravimetric analyzer (TGA/DTA) analysis. Following an intial plateau region, the decomposed woods rapidly decompose in a narrow temperature range of 300-4000C. After this sharp weight loss, there is a gradual but constant weight loss up to 9000C. The experiment indicates that decomposition occurs in discrete stages of hemicellulose evolution, cellulose decomposition and lignine degradation.
