Abstract
Pyrolytic process has a promising potential for the environmentally friendly upgrading of biomass and other materials such as plastics, coal. In this study, the influence of a biopolymer, polylactic acid (PLA) on the pyrolysis of corncob was investigated by using a fast pyrolysis fixed-bed reactor. The results indicated that the co-processing of PLA with corncob increased liquefaction yield and a lower water content as a function of the corncob/PLA ratio was obtained. Furthermore, the thermal degradation of corncob, PLA and their blends in nitrogen was studied at different temperatures by using TGA/FTIR. The gas evolved during degradation was identified by in situ FTIR. The results showed obvious synergies between corncob and PLA during co-pyrolysis.
