城市固体废弃物混合热解特性及动力学
Pyrolysis characteristics and kinetic study of mixed pyrolysis of municipal solid waste
摘要
Abstract
The interactions of pyrolysis in every two components were investigated by experiments based on the study of weight loss of single typical component of municipal solid waste (MSW). The results show that the pyrolysis of celery cabbage, cardboard and cotton cloth consist of three main stages. The pyrolysis characteristic of poly vinyl chloride (PVC) and waste tyre are relatively sophisticated, however they can be equiralently regarded as two and three stages, respectively. Their weight losses in the first two stages reach 100% and 88% , respectively. The corresponding pyrolysis temperature is slightly influenced by the blend of different components, while the rates are affected apparently. It can be concluded that the interactions of mixtures have little impact on the pyrolysis temperature. Moreover, the products or residues may promote or suppress the decomposition. The kinetic parameters of both single and mixed components were calculated in stages by the Coats-Red-fern method according to weight loss. The results show that the fitting curves show good linearity, indicating that it is reasonable to deal with the pyrolysis of single and mixed components in stages. In addition, with regard to the single and mixed pyrolysis of PVC and waste tyre, better linearity can be obtained by treating weight loss peaks with tight relations as one stage.关键词
