摘要:
针对生物质快速热解所制得的生物油黏度高、酸度高、含氧量高和水分高等缺点,提出了一种新型的生物油品质提升方法——乳化生物油/生物柴油.通过改变不同的反应条件发现,过高的乳化剂浓度会导致合并、结块,影响效果,过低则使乳化液不稳定; 较高的搅拌强度会产生较稳定的乳化液; 过长的反应时间将会导致乳化剂脱离生物油/生物柴油的表面.实验结果表明,最佳反应工况为乳化剂体积分数4%,原始生物油/生物柴油体积比4:6,搅拌强度为1 200 r/min,乳化温度30 ℃和混合时间15 min.另外,对乳化燃料的含水量、黏度、分子量和酸度等物性的测试结果表明,与生物油相比,这些性质均有较明显提高.
Abstract:
Bio-oil produced by fast pyrolysis of biomass is very viscous, highly acidic and does not ignite easily because of its high water content. To solve these problems, a novel method of emulsifying bio-oil with bio-diesel has been performed. In the present study, stable emulsions were achieved through appropriate processing conditions. Experiment results show that the best emulsifier concentration is 4% by volume. At higher concentration, there would be a rapid coalescence; and the emulsion is unstable at lower emulsifier dosage. The optimal initial ratio of bio-oil to bio-diesel is 4:6 by volume. Higher stirring intensity results in a more stable emulsion. The optimum stirring intensity is 1 200 r/min. Higher temperature induces the stability of emulsion, and the optimal emulsifying temperature is 30 ℃. The best mixing time is 15 min, beyond which the stability decreases due to the drop-out of the surfactant from the bio-oil/bio-diesel interface. Further, some properties like water content, acid number, molecular weight, viscosity were measured. Comparing with bio-oil, the properties of emulsion of bio-oil/bio-diesel are improved obviously.
