| Abstract: | In order to understand the thermal stability of the bio-oil/bio-diesel mixture,the physicochemical properties of the mixture stored at different temperatures for different time were analyzed.The fuel properties of the bio-oil/bio-diesel mixture,such as viscosity,water content,acid number and average molecular weight,were also measured before and after aging.The experimental results show that the water content is less than 0.7% when the mixtures are aged at 80℃ for 180h.The viscosity changes slightly with the increase of aging temperature and aging time.The chemical changes during the storage were characterized by using the gel permeation chromatography(GPC) and the fourier transform infrared spectrometer(FTIR).The results of the GPC exhibit a slight increase in the molecular weight,which is possibly due to some polymerization and condensation reactions during the storage.The results of the FTIR show the existence of O—H,C—H and stretch vibration.The increasing of the absorption intensity indicates the reaction of esterification during storage. |
