添加丙酮与乙酸乙酯对生物油稳定性的影响
Effects of acetone and ethyl acetate additives on the storage stability of bio-oil
摘要
Abstract
Different ratios (3%,6%,9%,12%,15%) of acetone and ethyl acetate were added into crude bio-oil from fast pyrolysis to invest the effects of these two additives on the storage stability of bio-oil. The results show that both acetone and ethyl acetate can reduce the water content of bio-oil, and the ethyl acetate performes better than acetone. Compared to the blank control group, the water content decreases by 17.8% (from 16.32% to 13.41%) at 15% dose of ethyl acetate. The viscosities of bio-oil decrease a lot after adding acetone and ethyl acetate, and acetone shows more obvious effect. With the increasing of additive dose, the viscosity of bio-oil decreases. The viscosity of bio-oil decreases more than that of the control group by 37.20%, 57.78%,71.92%,79.79%,84.67% with 3%,6%,9%,12%,15% dose of acetone, respectively. There is no significant difference in pH values among acetone and ethyl acetate addition groups and control group. According to the FT-IR and GC-MS analysis,it indicates that acetone and ethyl acetate inhibit the aging reactions of bio-oil during storage.关键词
