Study of Thermal Pyrolysis Knetics of Civil Sludge

Lian Wang

Abstract

The TG-DTG-DSC curves of two kind of sludge which were both from Nangchang Qingshanhu Sewage Treatment Plant were derived from tests of differential thermal balance.The result showed there are two DTG peak of sludge of digested sample in which the sludge quickly lost weight.With the thermogravimetry,Pyrolysis phenomenon and characteristics and kinetics of dried sludge were investigated.The kinetics parameters for the chemical reactions of the two kind of sludge were calculated and the reaction formulas were derived.
