Interpretive Summary:

Technical Abstract: An improved column-based process for production of biodiesel was developed using a column containing a strongly basic anion-exchange resin in sequence with a column containing a resin to which a lipase biocatalyst is bound. Currently most biodiesel is produced by transesterification of triglycerides, such as corn oil, with short-chain alcohols, such as methanol or ethanol, with a strong base as a catalyst. The transesterification reaction to produce biodiesel can also be accomplished using resin-bound lipases as biocatalysts. In this study, two columns were prepared, one containing the strongly basic anion-exchange resin DIAION® and the other containing Candida antartica lipase B enzyme bound to Sepabead® EC-EP resin. These columns individually both catalyzed the transesterification of a mixture of ethanol and corn oil, producing comparable yields of ethyl esters (biodiesel). When run in sequence, it was demonstrated that the yield of ethyl esters increased by 20%.
