摘要:The development of appropriate reactors is crucial for the production of biodiesel. In this study, a packed-bed reactor system using lipase-Fe_3O_4 nanoparticle biocomposite catalyst was successfully developed for biodiesel production based on soybean oil methanolysis. Emulsification before methanolysis improved the reaction rate. The lipase-nanoparticle biocomposite showed high activity and stability in the single-packed-bed reactor at an optimal flow rate (0.25mLmin~(-1)). After 240h of reaction, the conversion rate was sustained as high as 45%. The conversion rate and stability achieved using the four-packed-bed reactor were much higher than those achieved using the single-packed-bed reactor. The conversion of biodiesel was maintained at a high rate of over 88% for 192h, and it only slightly declined to approximately 75% after 240h of reaction. The packed-bed reactor system, therefore, has a great potential for achieving the design and operation of enzymatic biodiesel production on the industrial scale.
