The effects of ethyl acetate addition on the stability of bio-oil from rice straw fast pyrolysis were investigated through measuring the physicochemical properties of the bio-oil during storage. The results showed that by adding ethyl acetate of 1%, 6%, 11%, 16% and 21%, the final pH values of the bio-oils are increased by 0.66%, 2.33%, 3.65%, 4.32% and 6.31%, respectively; the final water contents are decreased by 10.90%, 20.17%, 28.19%, 30.27% and 35.10%, respectively; the final viscosities are decreased by 13.69%, 39.08%, 57.99%, 66.00% and 73.58%, respectively. The FT-IR and GC-MS analyses indicated that ethyl acetate can inhibit bio-oil from some aging reactions and reduce the content of organic acids.
