藻类生物柴油研究现状与展望

Research status and prospects for algae biodiesel: a review

随着世界能源危机和环境恶化的加剧,新型绿色燃料——生物柴油备受关注。目前,世界范围内主要以油料作物和动物脂肪为原料生产生物柴油,但存在很多局限性。藻类本身具有很多优点,以藻类为原料生产的生物柴油是真正的环保可再生能源,但是藻类生物柴油的生产工艺费用较高,生产技术还不成熟,仍需要进一步的研究。该文主要介绍藻类生物柴油的优越性、生产工艺以及研究现状,分析了生产过程中存在的问题,展望了未来藻类生物柴油生产工艺研究的重点和发展趋势。

With the aggravation of energy crisis and environmental pollution worldwide, biodiesel tuel has received more and more attention in recent years. At present, biodiesel is mainly derived from oil crops and animal fats, it can not meet environmental and economic sustainability. Lots of studies have shown algae are the most promising source for biodiesel production, so algae-based biodiesel has become more attractive. Because of its environmental benefits, algae-based biodiesel is considered as the most potential fuel alternative. As technologies for biodiesel production are sophisticated and costy, biodiesel production from algae is limited. This paper reviews the current status of microalgae used for biodiesel production, including its advantages and production process. Furthermore, production challenges and future perspectives for algae-based biodiesel production are also discussed.
