摘要The pyrolysis processes of the selected combustible solid wastes (CSWs) including poplar wood, polyethylene (PE), paper, rubber, rice and polyethylene terephthalate (PET) were investigated by thermogravimetric (TG) analysis. The pseudocomponents of the six kinds of selected CSWs were determined based on Weibull mixture model. The DAEM reaction model was used to study the pyrolysis kinetics of the samples. The results showed that the pyrolysis temperature of selected CSWs was ranged from 413.15 to 979.14 K and the Weibull mixture model can reproduce the TG and DTG curves accurately. The TG curve can be understood as a sum of two or three parallel reactions, where each single reaction was represented by one Weibull model component. It was observed that there were three pseudocomponents for the poplar and paper samples. There was one pseudocomponent for the PE sample. However, the rubber, rice and PET samples had two pseudocomponents. The activation energy (Ea) changed from 120 to 225 kJ mol(-1) in the range of the conversion rate from 0.15 to 0.85 for the six kinds of selected CSWs.
