原油价格以及随之而来的运输燃料价格的急剧上涨，加上环境问题的增加，导致美国和全世界生物柴油生产的迅速增长。随着生物柴油产量的增加，主要副产品甘油的产量也在增加。由于现有的甘油供需市场紧张，最近生物柴油精炼甘油产量的增加导致甘油市场供过于求。因此，甘油的价格大幅下降，生物柴油炼油厂面临着管理甘油副产品的有限选择。在生物柴油工业中，基本上已经变成了废物流。本文综述了甘油催化和生物转化为各种增值产品的有前途的选择，其中许多是石油衍生化学品的生物基替代品。(c)2007年美国化学工程师学会环境规划。
Dramatic increases in the price of crude oil, and consequently transportation fuels, coupled with increased environmental concerns have resulted in rapid growth in biodiesel production, both in the United States and worldwide. As biodiesel production increases, so does production of primary coproduct, glycerol. Since the existing glycerol supply and demand market was tight, recent increases in glycerol production from biodiesel refining has created a glut in the glycerol market. As a result, the price of glycerol has fallen significantly and biodiesel refiners are faced with limited options for managing the glycerol by-product. which in the biodiesel industry, has essentially become a waste stream. This article is a review of promising options for both the catalytic and biological conversion of glycerol into various value-added products, many of which are bio-based alternatives to petroleum-derived chemicals.
