摘要/Abstract

摘要： 乌桕籽的含油率高达40%，是生产生物柴油的优质原料。本研究采用绿色环保节能高效的乌桕籽油提取方法，以高压蒸汽作为水剂提取油脂的方法，进行了相关工艺的实验研究，以乌桕油脂皂化物为研究对象，通过微波极化皂化物羧基端促进脱羧制备优质烃类燃料。探讨了料液比、烘烤时间、烘烤温度、pH值、高压蒸汽处理时间等因素对油脂提取率的影响。微波裂解所得到液态产物为皂类干重的60%以上，裂解液态产物的密度为0.865 g/cm3，黏度2.73 mm2/s，与柴油的性质基本相似。研究结果为利用乌桕籽油生产生物柴油的工业化提供了一定基础。

Abstract: Chinese tallow seed contains as high as 40% oil. It is a good raw material for production of biodiesel. By microwave assisted decarboxylation of the potassium soap of Chinese tallow seed oil，renewable hydrocarbon fuel is obtained. In this efficient oil extraction process，high pressure vapor is used as extractor. In order to obtain a high extraction yield，some factors including solid/liquid ratio，baking time，baking temperature，pH value and high pressure processing time are investigated. The weight of microwave assisted pyrolysis liquid product is 60% of dry soap weight. The density of the liquid is 0.865 g/cm3 and the viscosity is 2.73 mm2/s，while its characteristic is similar to that of diesel fuel. Results in this study will give a useful information for the industrial production of biodiesel from Chinese tallow seed.

Key words: Chinese tallow seed oil, aqueous extraction oil, soap, decarboxylation
