糠醛渣热解特性的研究

The thermogravimetric analysis was used to study the pyrolysis characteristics of furfural residues. The result showed that furfural residues pyrolysis process had five distinct phases with increasing temperature. TG and DTG analysis and comparison were used to study the pyrolysis of furfural residues at different heating rate (5℃/min, 20℃/min, 50℃/min and 80℃/min) and different particle size distribution in a stream of N2. It showed that the beginning temperature of pyrolysis rose with the heating rate and particle size distribution increasing. Based on the experimental data, a pyrolysis kinetics model was proposed and the related kinetics parameters of furfural residues pyrolysis were determined. The results indicated that the pyrolysis process can be described by three-order model. These conclusions provided a theoretical foundation for further research on combustion and gasification of furfural residues.
