Non-oxygen thermo-analysis at three different temperatures was Performed for the 19 biogas source rock samples from Ying-Qiong Basin in South China Sea and Qaidam Basin in Qinghai Province. The results showed that the thermo-decomposing temperature was 260-270℃ for polysaccharides (such as cellululose, semi-cellose) and lipid compounds. Also, the thermo-decomposing temperature was lower than 320℃ for most of nucleic acids and proteins.Therefore, the thermo-decomposing value at 330℃ for 1 hr. could be used to estimate the production abundance of biochemical methane.
