能源微藻规模化培养影响因素的研究进展

Research progress on influencing factors of large scale cultivation of microalgae for energy production

微藻比陆生油料作物适应能力强、光合作用效率高,在二氧化碳减排、水污染治理以及生物基喷气燃料等领域具有重要的应用。本文从能源微藻规模化培养的影响因素出发,首先对影响微藻规模化培养的因素进行了综述,分别从生态学因素、气候因素、工艺因素和选址因素这四方面进行了介绍,重点介绍了微藻生物燃料所需土地、水资源和微藻培养新技术发展现状,提出了能源微藻大规模培养的技术难点和障碍。在此基础上,结合我国国情分析了微藻生物燃料发展面临的问题和挑战,探讨了我国能源微藻培养潜在的产量和适合养殖地区,并对我国微藻生物燃料的发展提出了展望。

Microalgae are more adaptable and photosynthetic than terrestrial oil crops, and have important applications in carbon dioxide emission reduction, water pollution control and bio-based jet fuels. In this paper, the influencing factors of large scale cultivation of microalgae for energy production are summarized. Firstly, four aspects including biological factors, climate factors, technological factors and site selection factors are introduced, and the development status of land, water resources and new technology for microalgae cultivation are mainly introduced. Moreover, the technical difficulties and obstacles in large scale cultivation of microalgae are put forward. On the basis, the problems and challenges faced by the development of microalgae-based biofuels are analyzed in terms of Chinese conditions, and potential production capacity and suitable areas for energy microalgae cultivation in China are discussed. Furthermore, the development of microalgae-based biofuels in China is also prospected.
