| Abstract: | Basic properties and pyrolysis characteristics of primary sludge, secondary sludge and advanced treatment sludge from paper mill were studied. According to the analysis of pyrolysis process by means of Coats-Redfern method and based on the calculated kinetic parameters of three kinds of sludge at 10℃/min heating rate. It is found that the reaction order of primary sludge is 2 at the organic pyrolysis region, the other two are 3. The activation energy of the three kinds of sludge are 43.80 kJ/mol, 32.74kJ/moland17.16kJ/mol, and their frequency factor are 1.56×10^6min-1, 1.18×10^7min-I and 2.60×10^8min-1 respectively. |
