摘要
利用非离子表面活性剂复配,对热解生物油/柴油混合液进行一系列乳化实验,测量乳化油的密度、热值、pH值。以乳化油的稳定性为实验指标,研究乳化剂种类、乳化剂用量、生物油含量对乳化油稳定性的影响。实验结果表明:在乳化温度为40℃(水浴),乳化时间为30min的条件下,以2%用量的Span80和Tween80复配乳化剂乳化生物油含量为20%的生物油/柴油混合液效果最佳。另外,随着生物油含量的增加,乳化油密度逐渐增加,热值与pH值逐渐减小。
Pyrolysis bio-oil/diesel oil was emulsified with complex of nonionic surfactants. The density, calorific value and pH value of the emulsified fuel were measured. The effects of surfactant type, surfactant content and bio-oil content in the emulsion on the stability of the emulsion were investigated. Experimental results show that the optimal emulsion could be obtained when the content of nonionic surfactants combined by Span 80 and Tween 80 is 2%, bio-oil content in biooil/diesel oil is 20%, and the emulsification time is 30min in a water bath of 40℃. When the bio-oil content increases, the density of the enulsion increase, and the pH and calorific value decrease.
