以废动植物油脂为原料,在自制DYD催化剂作用下生产生物柴油,详细介绍了生产生物柴油的工艺过程、分析方法、产品质量以及在柴油机上的试验情况,通过正交试验确定了生产生物柴油的最优工艺条件,即醇油摩尔比4∶1,催化剂用量2%,反应温度75℃,反应时间8 h。测试结果表明,所生产的生物柴油各项性能指标都达到美国同类产品的标准(D6751-03a),在动力性、经济性基本不变的情况下,其环保性能指标明显改善,完全能在柴油机上应用。
The bio-diesel was produced under the action of self-made DYD catalyst. The process, the analysis method, the quality of the product and the test on the diesel engine were introduced in detail. The orthogonal test was used to determine the production of biodiesel The optimum conditions, namely the molar ratio of alcohol to oil 4: 1, the amount of catalyst 2%, the reaction temperature 75 ℃, the reaction time 8 h. The test results show that the performance indicators of the biodiesel produced have reached the standard of similar products in the United States (D6751-03a). Under the condition of basically unchanged power and economy, the environmental performance indexes of the biodiesel significantly improve, On the application.
