固定化脂肪酶生产生物柴油的研究进展

Research progress of biodiesel production catalyzed by immobilized lipase

脂肪酶作为一种清洁的催化剂,可用在生物柴油的生产中,解决燃油危机,环境污染等诸多问题。固定化脂肪酶与游离脂肪酶相比具有很好的稳定性和催化性能,脂肪酶固定化的方法主要有吸附、共价结合,交联、包埋等。影响固定化脂肪酶催化酯交换反应生产生物柴油的主要因素有温度、甲醇、甘油和含水量。本文就固定化脂肪酶催化生产生物柴油方面的研究进展作一综述,希望引起对固定化脂肪酶催化生产生物柴油技术的更多关注。

Lipase can be used in biodiesel production as a clean catalyst to solve the problem of energy shortage and environmental pollution. Immobilized lipase is more stable compared with free lipase and has better catalytic properties. Preparation methods for immobilized lipase include adsorption, covalent binding, cross-linking and entrapment. There aremany factors that affect the efficiency of the biodiesel transesterification reaction, such as temperature, methanol, glycerol and water content. The research progress about lipase catalyzed biodiesel production was reviewed. To attract more attention to new techniques of immobilized lipase-catalyzed biodiesel production was hoped.
