摘要
Kinetic triplets and thermodynamics are important in the design of pyrolysis processing. In this study, the non-isothermal kinetics and thermodynamics of pseudo components of bamboo flour (BF), Polylactic acid (PLA), and the resulting BF/PLA composite were investigated using Fraser-Suzuki deconvolution. Fourier-transform infrared spectra (FTIR) was used to characterize the gaseous products. Results showed the Fraser-Suzuki deconvolution curves fitted well to the experimental data. For pseudo hemicellulose and pseudo components in PLA, common kinetic models were applied. The pyrolysis of pseudo cellulose met the random scission model and pseudo lignin need to be described with empirical model. The Kinetic models were verified and shown to be in good agreement with the experimental results FTIR results indicated that more radical reactions occur in PLA during co-pyrolysis with BF.Thermodynamic results indicated the pyrolysis of pseudo components were non-spontaneous reactions except lignin. These results will contribute to reactor design and scale-up in future.
