Effect of alkali and alkaline earth metals on co-pyrolysis characteristics of municipal solid waste and biomass briquettes

The pyrolysis characteristics of pine powder and polyvinyl chloride (PVC), respectively representing the biomass and plastics components of municipal solid waste, were studied in a thermogravimetric analyzer, and the influence of heating rate on pyrolysis characteristics was also investigated. The pyrolysis temperature was heated from ambient up to 900 °C at different heating rates including 10, 20 and 40 °Cmin-1. The pyrolysis of pine powder was composed of two obvious weight loss phases, which were dehydration and the decomposition of cellulose and hemicellulose. The lignin in pine powder decomposed over a broad temperature range until 900°C. The pyrolysis of PVC was complicated, and included the release of hydrogen chloride (HCl), the formation of hydrocarbons. Besides, the additives in PVC decomposed at about 600 °C. The TG and DTG curves of pyrolysis for pine powder and PVC were similar at different heating rates, however, each weight loss phase of pyrolysis was shifted to high temperature with increasing the heating rate.

Pyrolysis Characteristics

Wood-based materials from Municipal Solid Waste have the potential of covering a significant part of the future demand on gasification capacities. However, their pyrolysis kinetics and gasification behavior has not yet been fully investigated. This paper describes the pyrolysis characteristics of typing paper and Chinese parasol from municipal solid waste applying the non-isothermal thermogravimetric analysis, the apparent activation energy and the pre-exponential factor were obtained by kinetics analysis at the heating rate of 10/20/40 oC•min-1.
