Abstract:

Microalgae is the fastest growing plant on the earth. As a resource for biodiesel production，microalgae is one of the most competitive options for biofuel industry. In this article，the process of biodiesel produced from oilgae is introduced，consequently，units of process such as screening of algae strain，cultivation system of algae，algae harvesting，extraction of algae oil and conversion of algae oil to biodiesel are elucidated independently. Especially，various microalgae cultivation systems including open pond as open system and photobioreactors as closed system for mass production of algae are discussed in detail. The advantages and disadvantages of different cultivation systems are compared and advances of cultivation systems are summarized. Finally，trends and research areas in microalgae-biodiesel industry are proposed.

摘要：

微藻是地球上生长最快的植物，利用含油微藻作为生物柴油的原料来源是生物燃料产业最具竞争力的选择之一。本文首先介绍了含油微藻制备生物柴油的工艺过程，然后对产油微藻的筛选、微藻培养系统、微藻的收集分离、藻油的提取、微藻油脂制生物柴油过程分别进行了阐述，其中就用于微藻规模化培养的循环渠开放系统和各种光生物反应器的封闭系统进行了较为详细的讨论，指出了各种系统的优缺点和最新研究进展。最后，就微藻产生物柴油产业的发展趋势和研发方向提出了建议。
