该文以生产达标的文冠果生物柴油为目的。通过设计其生产工艺流程，分别在转化温度为60和70℃的条件下生产了2种生物柴油，并测定了0#柴油分别与2种生物柴油以一系列不同掺混比（0、10%、20%、30%、40%、50%、60%、70%、80%、90%、100%）混合的燃料的理化性质（密度、运动黏度、闪点、凝点和馏程）。结果表明：转化温度为70℃的生物柴油各理化性能要优于转化温度为60℃的生物柴油；生产的2种生物柴油与0#柴油在掺混比不超过20%时，各项理化性能指标均符合国家车用柴油标准，达到应用要求。

The development of renewable energy resources has attracted much attention due to the depletion of fossil fuels and severe environmental pollution. Biodiesel, an alternative fuel extracted from biological sources such as vegetable oils, animal fats, or waste cooking oils via transesterification, which is biodegradable, non-toxic and renewable energy, with higher flash point, excellent lubrication and a higher cetane number. The exhaust gas from biodiesel contains a small quantity of SOx, CO, and suspended particles. Xanthoceras sorbifolia bunge, a typical oil plant, usually about 2-6 m in height, is mainly distributed around the Inner Mongolia area of China. Its yellow ripe fruit consists of a white seed core and a dark black shell structure. A 10-year-old Xanthoceras sorbifolia bunge tree yields 10-15 kg of fruit and yields up to 1-1.5 tons per hectare. Historically, these Xanthoceras sorbiflia bunge trees were planted in a large scale for obtaining the oil containing unsaturated fatty acids. Xanthoceras sorbifolia bunge is a superior raw material for extracting biodiesel, due to the fact that it contains unsaturated fatty acids and 50 percent oil concentration. Therefore, Xanthoceras sorbiflia bunge has a significant potential of being used as a feedstock for biodiesel production. To meet the requirement for producing large scale yields of biodiesel, the synthesis of biodiesel from Xanthoceras sorbiflia bunge seed oil by transesterification was carried out via biodiesel conversion equipment-fuelpod2. The structure and reaction principle of the fuelpod2 device is introduced first, and then the practical conditions of producing biodiesel by Xanthoceras sorbiflia bunge seeds oil is investigated via transesterification. The optimum preparation conditions are as follows:reaction time is 3 h, reaction temperatures are 60 and 70℃, the amount of catalyst is 1%wt, methanol-to-oil molar is 6:1, and each batch of processing crude oil is 50 L. This study mainly focuses on the synthesis of biodiesel extracted from Xanthoceras sorbiflia bunge, the characteristics of which conform to the national standard. The production strategy is designed to tune the reaction time, reaction temperature, and amount of catalyst. Two categories of biodiesel are obtained via changing the temperature of 60 and 70℃, respectively. The 0# pure diesel oil is mixed into the above two categories of biodiesel, respectively, with a ratio series of (0, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%). The physical and chemical properties (density, kinematic viscosity, flash point, condensation point, and distillation range) are investigated. The results illustrate that the physical and chemical properties of the biodiesel which is produced via the 70℃transition temperature strategy is superior to that of 60℃. When the mixing ratio of the two categories of biodiesel and 0# pure diesel is less than 20%, and the physical and chemical performance of the two categories of biodiesel conform to the national diesel standards for vehicles, it is expected that the Xanthoceras sorbiflia bunge biodiesel can be introduced into the market.
