Study On Co-pyrolysis Of Furfural Residue And Rice Husk

Furfural residue is a deposed product produced by hydrolyzing farming byproducts for furfural (called furan formaldehyde again). Rice husk is the most vast and extensive agriculture by-product. Utilizing bio-energy efficiently and reasonably can not only reclaim energy sources but also alleviate environment pollution. Pyrolysis is an effective way when biomass been transformed into gaseous or liquid fuels, and supplys fundamental investigation for further extensive use. As different kinds of biomass have different pyrolysis characters, study on co-pyrolysis of furfural residue and rice husk can cast a view on co-dispose of these two biomasses.Using Pyris-1 TGA thermogravimetric analysis instrument, the pyrolysis and co-pyrolysis characteristic of furfural residues and rice husk were researched under conditions of different heating rates, grain radius and weight ratios. Co-pyrolysis of biomasses was not simply additive of its individual contributions. During the main pyrolysis temperature region, a two-step and different reaction series pyrolysis kinetics model was developed which was fit for the intrinsic property of the blends and the related kinetics parameters were determined. Such model was verified by Newton-coats numerical integral method and the result indicated its reliability and practicability.Based on the relationship of influential factors of furfural residue and rice husk co-pyrolysis and char yields, a RBF network was set up, and was used in char yields forecast. The forecast results proved that the application of RBF into thermogravimetric pyrolysis of biomass is not only feasible but also a simple and new way for biomass pyrolysis studies.
