Sažetak
Co-pyrolysis of biomass with different waste plastics might be a promising alternative for producing high-quality alternative fuels and dealing with the emerging problem of waste disposal. Plastics materials have properties similar to those of fossil fuels in terms of heating value and absence of oxygenated compounds ; therefore, they could significantly improve biomass products properties, especially bio-oils. To scale-up the process on an industrial level, it is of great importance to ensure high-quality product yield, but even more, it is an absolute necessity to develop a method for the prediction of product yield and distribution. This could be done by observing the results from Ultimate and Proximate analysis, product yield from individual pyrolysis, and considering the influence of synergistic effect. In this work, we present the model for product yield for the co-pyrolysis of biomass sawdust with polystyrene, polypropylene, and polyurethane foam. The model is based on the calculated theoretical yield and a mathematical relationship established for the synergistic effect of the selected critical mixtures of biomass and plastic feedstock. The presented model for predicting product yield gives an excellent accuracy for investigated feedstock, even though investigation should continue to ensure reproducibility of the method for other types of biomass feedstock. Furthermore, an additional conclusion is given regarding the optimal share of plastic content in the fuel mixture, observing the bio-oil quality.
