摘要

生物柴油是一种可替代的液体生物燃料,由甲酯或乙酯的混合物组成。它可以通过酯交换反应生产,其中低分子量醇(例如甲醇或乙醇)与脂质或脂肪(甘油三酯)反应产生生物柴油(脂肪酸甲酯FAME)和甘油作为有价值的副产物。最常见的生物柴油生产方法是碱催化酯交换反应,其中碱性物质如氢氧化钾被用作催化剂。提出了一种处理低游离脂肪酸、游离脂肪酸、废植物油和WVO约24吨/天的生物柴油装置新工艺设计方案。

Methanolysis of Low FFA Waste Vegetable Oil using Homogeneous Base Catalyst for Biodiesel Production: New Process Design
Biodiesel is an alternative liquid biofuel consists of a mixture of methyl or ethyl esters. It can be produced through transesterification where low molecular weight alcohol (e.g. methanol or ethanol) reacts with lipid or fat (triglyceride) to produce biodiesel (fatty acid methyl ester FAME) and glycerol as a valuable byproduct. The most common method of biodiesel production is base catalyzed transesterification where alkaline material such as potassium hydroxide is used as a catalyst. This paper presents a suggested new process design of a biodiesel plant that treats about 24 tons/ day of low free fatty acids, FFA, waste vegetable oil and WVO.
