阅读说明：本技术 生产生物柴油、柴油范围的烃和由其获得的产品的方法和装置 (Method and apparatus for producing biodiesel, diesel range hydrocarbons and products therefrom ) 是由 J·M·怀特 大卫·A·斯莱德 M·R·哈弗尔利 拉明·阿布哈里 C·J·埃伦 于 2019-05-01 设计创作，主要内容包括：由含有不皂化材料的可再生原料(例如脂肪、油和油脂)产生粗生物柴油的方法；通过纯化工艺纯化粗生物柴油；回收纯化的生物柴油馏出物流和挥发性较小的生物柴油残余物流；并从生物柴油残留物中进一步回收有价值的化学品。具体而言,本发明涉及浓缩生物柴油生产的生物柴油残余产物中有价值的化学品,以及随后回收这些有价值的化学品。该方法还可以包括使用加氢脱氧将生物柴油残余物转化为柴油范围的烃,并随后纯化由此产生的烃馏分。(A process for producing crude biodiesel from renewable feedstocks containing unsaponifiable materials (e.g., fats, oils, and greases); purifying the crude biodiesel by a purification process; recovering a purified biodiesel distillate stream and a less volatile biodiesel residue stream; and further recovering valuable chemicals from the biodiesel residue. In particular, the present invention relates to the concentration of valuable chemicals in the biodiesel residue product of biodiesel production and the subsequent recovery of these valuable chemicals. The process may also include converting the biodiesel residue to diesel range hydrocarbons using hydrodeoxygenation and subsequently purifying the hydrocarbon fraction produced thereby.)
