【摘要】 本文提出了采用细胞固定化技术制备整体生物催化剂生产生物柴油的新思路,并立足于我国丰富的废油脂资源,获得清洁车用生物柴油。不仅提高了废油酯的转化率、同时实现了副产物甘油的循环利用,儿乎不排放污染物。所制备的整体生物催化剂可循环利用300小时以上,也可以通过微生物培育实现再生。本研究的目的一方面是为了彻底解决酸/碱催化工艺的二次污染问题,另一方面整体生物催化剂的应刚减少了酶纯化和固定化的步骤,对于目前正在研发的生物法工艺来说,大幅度降低了生产成本,加大了其商业化的可能性。更多还原

【Abstract】 A novel attempts to produce bio-diesel by whole-cell biocatalyst with immobilized cell technology is suggested in this paper, and the clean vehicle bio-diesel is obtained from the abundant waste oils/fats in China. The conversion rate of waste oils/fats is increased, the by-product of glycerol can be recycled and almost no contamination in this process. The whole-cell biocatalyst can be repeatable used more than 300 hours and regenerated by Cultivation of microorganism. The goal of the research is to resolve the secondary pollution encountered by the alkali or acid-catalyzed process, at the same time reduce the complexity of purification and immobilized process required by the current lipase-catalyzed process, the cost of the bio-process would be decreased dramatically and its commercial possibility is boosted up.更多还原
