Taiyuan environmental sanitation research institute, Taiyuan, 030002) Abstract: The pyrolysis and combustion characteristics of pressure sensitive adhesives wastes (PSAs) were investigated by thermal gravimetric analysis under nitrogen and air atmosphere, moreover, the kinetics parameters of PSAs pyrolysis and combustion both were calculated using Doyle method. The results indicated that there depicted similar between the pyrolysis and combustion of PSAs. However, there existed three weightloss peaks during pyrolysis and two peaks in combustion for temperatures of 300℃~600℃.The kinetics results showed that the process of PSAs pyrolysis consisted of multi-stage cracking reactions, which could be described as four first-order reactions; the apparent activation energy in the first peak scale decreased, while in the second peak scale, the third peak scale of the pyrolysis and the fourth peak scale of the semi-coke cracking stage increased with the rising of heating rate. PSAs combustion could be described as three first-order reactions, in which the apparent activation energy decreased with the increase of heating rate. What’ more, the apparent activation energies in combustion exhibited lower than those in pyrolysis.
