Abstract pyrolysis characteristic of sludge under different heating rates was studied with thermogravimetric analysis, pyrolytic reaction kinetics model was set, Kinetic parameters of sludge pyrolysis reaction was calculated. The study showed that sludge pyrolysis included water precipitation, Volatile analysis and mineral salt and coke decomposition phase, volatilization with Mineral salts and coke, volatile de-volatilization was important the zero-g period of sludge, with 75% mass loss, a large amount of organic matter cleaved at this stage. High heating rate enabled to improve activation energy of sludge and predisposing factors, high organic matter content of sludge pyrolysis reaction activation energy refers to the former factor, is less than the low organic matter content in the sludge, with easy pyrolysis reaction, high conversion rate, harmless and resource utilization of sludge.
