Pyrolysis Of Biomass

Aspen Plus is a process software with great functions, almost all chemical process could be described by using it. Based on experimental equipment composition and related experimental results, a simulation model of biomass pyrolysis process occurring in a fluidized bed reactor is successfully developed. Via sensitivity analysis on products’ output change along with reaction temperature’s change and analysis of mutual relationship between fractions of product residues, reaction regulation of biomass pyrolysis process could be received. As a result, this model provides a useful description of the process for producing gas, liquid and solid products, however, receiving more data from experiment is the precondition of the simulation model’s optimization.

Abstract Overuse of polymer products has led to severe environmental problems, which are threatening survival of creatures on earth. It is urgent to tackle enormous polymer wastes with proper cycling methods. Pyrolysis of polymers into high-value chemicals and fuels is displaying great potential to address the white pollution issue. In this study, we focus on chemical recycling of polystyrene, an important polymer in our everyday life, into valuable chemicals through simple pyrolysis strategy under nitrogen protection. It is found that yield of liquid product from polystyrene pyrolysis achieves as high as 76.24%, and there exists single component in the liquid product, which has been identified as styrene through hydrogen nuclear magnetic resonance spectra. Moreover, we propose monomer dissociation mechanism to explain the pyrolysis process of polystyrene based on the structure of polystyrene and experimental results.
