Pyrolysis Behaviour

Alternative fuels, such as municipal solid waste (MSW) tend to play an increasingly important role in Chinese energy supply. Gasifying fuels derived from MSW have the potential of covering a significant part of the future demand on gasification capacities. However, their pyrolysis behaviour was not clear due to that the reactions during co-pyrolysis of the MSW serval fractions have not yet been fully investigated. In this paper, thermal behavior of pork, polypropylene and their blends were investigated by thermogravimetry under pyrolysis conditions via the non-isothermal thermogravimetric analysis. The pyrolysis and co-pyrolysis kinetics characteristics of the waste samples was investigated at a temperature range of 50 to 1000 °C with the heating rate of rate of 10, 20, 40 °C·min−1 and for particle sizes less than 74 μm. The results indicated that pyrolysis rate of pork was hindered by polypropylene. Negative synergistic effects on mixture decomposition was observed. Weight loss of mixture were lower than that calculated from individual samples for pork and polypropylene. The apparent activation energy were obtained through Kissinger and Ozawa methods for the samples. The results indicated that more energy for blends to be decomposed during co-pyrolysis.

For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.

The aim of this study was to evaluate the effect of the inoculum to substrate ratio (ISR) and the mixture ratio between organic fraction of municipal solid waste (OFMSW) and sewage sludge (SS) on the methane production potential achievable from anaerobic co-digestion (AcoD). Biochemical Methane Potential (BMP) assays at mesophilic temperature were used to determine the best AcoD configuration for maximizing methane yield and production rate, as well as to address possible synergistic effects. The maximum methane yield was observed at ISR of 1 and 60% OFMSW :40% SS as co-digestion mixture, whereas the highest methane production rate was achieved at ISR of 2 with the same mixture ratio (207 mL/gVS/d). Synergistic effects were highlighted in the mixtures having OFMSW below 60%, determining an increase of approximately 40% in methane production than the OFMSW and SS digestion as a sole substrate. The experimental data demonstrated that co-digestion of OFMSW and SS resulted in an increase in the productivity of methane than anaerobic digestion using the sole substrates, producing higher yields or production rates while depending on the ISR and the mixture ratio.
