Abstract

Bi-oil, the liquid product from biomass fast pyrolysis, is a kind of clean and sustainable fuel. However, its physicochemical characteristics are not stable, which hinder its actual applications. In this research, bio-oil made from rice husk by a commercial-scale biomass fast pyrolysis plant was utilized to investigate the effects of long period storage (two years) under three different conditions: at 4 °C in a refrigerator, at 25 °C in a room, and at outdoors in the nature conditions. In each condition, three samples collected from the upper, middle and the bottom of the containers. The results showed that low temperature (4 °C) can slow down the process of degradation during storage. The bio-oils endure the most severe aging process at 25 °C in a room. The maximum value of the viscosity was obtained from the bottom layer of bio-oil stored at 25 °C (348.5 ± 2.9 mm2 s−1), which is 50.8 times higher than that of the original bio-oil. The alcohols, furans and hydrocarbons are prone to accumulate in the bottom layers. This research could give insight on degradation of bio-oils at the distinct storage conditions and will be useful for designing the storage system and maintaining the quality of bio-oils in transportation and storage.
