摘 要：摘 要：微藻是光合效率最高的原始植物之一，与农作物相比，单位面积的产率可高出数十倍。微藻生物柴油技术首先包括微藻的筛选和培育，获得性状优良的高含油量藻种，然后在光生物反应器中吸收阳光、CO2等，生成微藻生物质，最后经过采收、加工，转化为微藻生物柴油。完整的微藻生物柴油成套技术链涵盖多个技术环节，是一个复杂的系统工程，包括微藻生物工程技术、微藻高效规模化养殖技术，以及微藻生物质采收、加工与转化技术等。其中，降低生产成本是当前微藻生物柴油研究面临的主要挑战，各国的研究机构为此开展了多方面的研究。

Abstract: Abstract: Microalgal is one of the most efficient original photosynthetic plants, with a yield per unit area tens of crops. Microalgae biodiesel technologies include microalgae screening and cultivation, photobioreactor design, and biomass harvest and transformation into biodiesel. Complete microalgae biodiesel technology chain covers a wide range of technical processes, and thus requires systematic research and developments. At present, lowering production costs is the main challenge microalgae biodiesel researches facing, and many countries have carried out researches to resolve this problem.
Key words: microalgae; biodiesel; photobioreactor; closed tube; transesterification
