生物柴油是一种由传统上来源于植物油或动物脂肪的单烷基酯组成的燃料。目前，对生物柴油和来自可再生生物质的其他燃料的兴趣和需求空前增加。然而，纯植物油或种子油是昂贵的，并且占总生物柴油生产成本的70%至85%。城市污水污泥作为生物柴油生产的脂质原料在美国和世界各地越来越受欢迎。它是丰富的，包括显着浓度的脂质，可以使生产生物柴油的污泥有利可图。然而，利用废弃污泥生产生物柴油面临着挑战。确定如何最好地收集不同的馏分并处理它们以最大限度地提取脂质是一项重大挑战。为了加速生物柴油的生产，已经提出了助溶剂和高剪切混合。然而，有很少的信息，成本效益的手段，增加脂质溶解度。
Biodiesel is a fuel comprised of monoalkyl esters traditionally derived from vegetable oils or animal fats. There is currently an unprecedented increase in interest and demand for biodiesel and other fuels derived from renewable biomass. However, pure vegetable or seed oils are expensive and constitute between 70% and 85% of the overall biodiesel production cost. Municipal sewage sludge is gaining traction in the U.S. and around the world as a lipid feedstock for biodiesel production. It is plentiful and consists of significant concentrations of lipids that can make production of biodiesel from sludge profitable. However, there are challenges to be faced by biodiesel production from waste sludge. Determining how best to collect the different fractions and treat them for maximum lipids extraction is a major challenge. To accelerate biodiesel production, cosolvents and high shear mixing have been proposed. Nevertheless, there is very little information on the cost-effective means of increasing lipid solubil...
