Effect of Heating Rate on the Deinking Sludge Pyrolysis Character

Article Preview

Abstract:

In this paper, the thermogravimetic (TG) and differential thermogravimetric (DTG) curves of deinking sludge from Huatai Group Co., Ltd were derived from tests of thermal gravimetric analyzer (TGA). Pyrolysis character and kinetics of deinking sludge were investigated using thermalanalysis. The result showed that the pyrolysis process was composed of three stages: water lose stage, organic decomposition and decomposition of residues. The dynamical model of this pyrolysis process could be expressed by three first-order parallel reaction. The kinetic parameters of pyrolysis reaction were calculated respectively by Coats-Redfern integration method, the effect of heating rate on the deinking sludge pyrolysis characteristics was discussed.
