Effect of ethyl acetate addition on the stability of bio-oil

Biomass Energy Engineering Research Centre, School of Agriculture and Biology, Shanghai Jiao Tong University, Shanghai 200240, China

摘要

摘要: 以稻草秸秆快速热裂解生物油为样品,选取乙酸乙酯作为添加剂,按不同质量分数(分别为1%、6%、11%、16%和21%)添加到生物油中,考察原始生物油(空白组)及乙酸乙酯组生物油理化特性随贮存时间的变化规律。结果表明,随着乙酸乙酯添加质量分数增大,各乙酸乙酯组(1%、6%、11%、16%和21%)生物油最终pH值比空白组分别提高0.66%、2.33%、3.65%、4.32%和6.31%;最终含水率比空白组分别降低10.90%、20.17%、28.19%、30.27%和35.10%;最终运动黏度比空白组分别降低13.69%、39.08%、57.99%、66.00%和73.58%。FT-IR和GC-MS分析结果表明,添加乙酸乙酯能抑制生物油老化反应。此外,GC-MS分析结果还证实乙酸乙酯可以减少生物油内有机酸含量。

Abstract: 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.
