Research for tocotrienol recovery and biodiesel production from waste rice bran oil

本研究的目的是构建一种新的反应分离工艺，用于从植物油精炼过程中排放的废油中提取生物活性物质生育三烯醇(维生素E)和可再生能源优质生物柴油。该工艺包括游离脂肪酸在阳离子交换树脂催化下的酯化、生育三烯醇在阴离子交换树脂上的吸附、生育三烯酚在树脂上的解吸和甘油三酯在阴离子交换树脂催化下的酯交换反应。考察并阐明了每一步连续操作的最佳条件。

The purpose of this research is to construct a novel reaction and separation process for producing bioactive compounds, tocotrienol (vitamin E), and renewable energy, high quality biodiesel, from waste oils discharged in the vegetable oil refining process. The process consists of the esterification of free fatty acid using cation-exchange resin catalyst, the adsorption of tocotrienol on the anion-exchange resin, the desorption of tocotrienol from the resin and the transesterification of triglyceride using anion-exchange resin catalyst. The optimal conditions for continuous operation in each step were investigated and elucidated.
