【摘要】 生物质油是生物质快速热解液化的产物,与生物柴油乳化后可得到一种新的可再生清洁燃料。利用超声波乳化装置制备生物柴油-生物质油乳化燃料,首先采用亲油亲水平衡(HLB)值法确定了生物柴油-生物质油乳化燃料乳化剂的最佳HLB值,然后研究了乳化燃料制备过程中各种乳化条件对乳化燃料稳定性的影响。结果表明,生物柴油-生物质油乳化燃料乳化剂的最佳HLB值为4.3~4.7,乳化时间、乳化温度、生物质油浓度及乳化剂浓度等对乳化燃料的稳定性均有一定的影响。更多还原

【Abstract】 Bio-oil produced from biomass by fast pyrolysis can be emulsified with bio-diesel,forming a new kind of clean renewable energy.The emulsions from bio-diesel and bio-oil are produced by using ultrasonic emulsification method.Meanwhile,the optimum hydrophilic and lipophilic balance(HLB) value of the emulsifier for bio-diesel and bio-oil emulsified fuel and the influence of emulsification conditions on the emulsion stability are investigated.Results show that the optimum HLB number of the emulsions from bio-diesel and bio-oil is from 4.3 to 4.7,and the emulsification time,emulsification temperature,emulsifier and bio-oil concentration have great influence on the emulsion stability.更多还原
