摘要: 介绍了一种新型木质素柴油的制备工艺优化方法及其理化性质评价。根据添加木质素的比例、乳化剂的添加量和等影响因素进行正交试验设计,分别选择添加木质素的量为总质量2%、3%和4%的比例,以乳化剂的用量为4%、5%和6%,HLB为8.3、8.8和9.3以及0.2、0.3和0.4 g的助乳化剂用量的不同等条件为水平标准,配制了多种不同比例的乳化油,最终筛选乳化条件为:HLB值为9.3,乳化剂的用量为6.0%,助乳化剂的加入量为1.2%,乳化温度为室温,乳化时间2 min。同时还针对氧化安定性、含硫量、酸度、10%蒸余物残炭、铜片腐蚀、机械杂质、运动粘度、凝点、闪点(闭合)、十六烷值、馏程、密度十二项指标进行了国家标准检测均高于GB 252-2000轻柴油的国家标准。其中木质素柴油的十六烷值均到了46.1和48.8,远远超过了45的国家标准;这对开发柴油的替代燃料,缓解燃料供需紧张矛盾,降低燃料消耗率等都有重大意义。

Abstract: We mainly introduced the optimization preparation process and the physical and chemical properties of the lignin diesel fuel. According to the lignin's proportion, the emulsifier content and other influence factors, we used the orthogonal experiment design to optimize experiment. The choice of lignin quantity is 2%, 3% and 4% for total quality, the dosage of emulsifier is 4%, 5% and 6%, HLB is 8.3, 8.8 and 9.3, and the auxiliary emulsifier dosage is 0.2, 0.3 and 0.4 g, respectively. With different level condition as the horizontal standard,we took lots of different ratio of emulsified oil, and finally confirmed the optimal preparation conditions: HLB 9.3, the dosage of emulsifier 6.0%, auxiliary emulsifier dosage 1.2%, emulsifying temperature is room temperature and emulsifying time is 2 min. Simultaneously we also carried on the national standards examination aimed at the oxidized stability, the sulphur content, the acidity, 10% to steam the excess carbon residue, the sheet copper to corrode, the mechanical impurity, the kinematic viscosity, the condensation point, the flash point(closed), the cetane number, the distillation, and the density. All indexes are higher than the GB 252-2000 light diesel oil the national standards. The lignin dieselcetane number arrived at 46.1 and 48.8, which is far beyond the national standard 45. Therefore, this kind of lignin diesel could save energy and reduce pollution obviously. It has great significance to develop the diesel oil substitution fuel, alleviate fuel supply, and cut the specific fuel consumption.
