Sažetak
Alternative fuels are crucial for decarbonisation of high-energy demanding processes. The utilisation of waste materials to produce alternative fuels is beneficial since it could effectively integrate waste management with the energy production sector. This is especially important for non-recyclable waste like rigid polyurethane foam, in which recycling implies a complex and expensive processes. Lately, the co- pyrolysis of waste plastics and biomass was introduced, since the synergistic effect might enhance the product properties compared to those of individual pyrolysis. Furthermore, the utilisation of waste biomass, like sawdust, is interesting since it does not influence the sustainability of biomass consumption and even more, it avoids the usage of raw feedstock which could be utilized more effectively elsewhere. Thermogravimetric analysis is performed to determine the thermal degradation mechanism of investigated mixtures with the intention to find the most appropriate utilisation method. Co- pyrolysis was conducted for three mixtures with following biomass/polyurethane ratios: 75-25 %, 50-50 %, 25-75 %, over a temperature range of 30- 800 °C, at two heating rates 10 and 20 °C/min, under an inert atmosphere. Obtained results were subjected to comprehensive kinetic analysis in order to determine effective activation energy and to provide a detailed analysis of the thermal degradation process for the considered samples. This work aimed to identify main thermal decomposition stages during co-pyrolysis of biomass and polyurethane mixtures and to provide the influence of the mixture composition on the considered thermochemical conversion process. Kinetic analysis of the co-pyrolysis process for waste materials is seldom in literature, and this represents the main novelty of this work.
