Abstract
Biomass as a renewable energy source can be utilized to generate biochar, biogas, and bio-oil through pyrolysis. Bio-oil can be upgraded to produce biofuels as an alternative to crude oils. Plastic waste is one of major waste sources and is hard to be recycled. Through the co-pyrolysis with biomass, plastic waste can be used to produce high-quality biofuels. On the other hand, the design of co-pyrolysis is challenging, because of the complexity of biomass and plastics. The fundamental understanding about co-pyrolysis kinetics is essential for the commercialization of co-pyrolysis. In this project, a series of experiments will be conducted to investigate co-pyrolysis of biomass and plastic waste. To study the kinetics, a scheme in which a knowledge-based model is combined with an experience-based model will be proposed to predict the process. In the proposed scheme, a parallel-reaction kinetic model will be developed as a knowledge-based model while an artificial-neural-network (ANN) model will be established as an experience-based model. The combined knowledge-experience based model will provide a thorough understanding on the co-pyrolysis. The findings from this project will be applied to facilitate the design and commercialization of the co-pyrolysis.
