| Popis: | Laser-induced fluorescence was used to simulate and monitor the effect of ultraviolet (UV) exposure on the chemical stability of bio-oil. Bio-oil obtained from fast pyrolysis of biomass has potential for replacing fossil fuel in the future as liquid fuels. Pyrolysis-derived bio-oil contains up to 400 chemical compounds and tends to be very unstable, both physically and chemically. Bio-oil produced from four different sources (pine lumber, pine bark, oak bark, and oak wood) was used in this study. Synthetic bio-oil composed of 10 chemicals but having a similar weight percentage (wt %) of compound groups and having a similar spectroscopic property as bio-oil was prepared. Synthetic bio-oil simplifies the limitation in the study posed by complex chemical composition in bio-oil. It was concluded that phenols present in the bio-oil show chemical instability by giving time-dependent fluorescence intensity. |
