Biodiesel production via trans-esterification using Pseudomonas cepacia immobilized on cellulosic polyurethane.

Li, Li and Dyer, Philip W. and Greenwell, H. Christopher (2018) 'Biodiesel production via trans-esterification using Pseudomonas cepacia immobilized on cellulosic polyurethane.', ACS omega., 3 (6). pp. 6804-6811.

Abstract

In this work, Pseudomonas cepacia lipase immobilized on cellulosic polyurethane was used as a catalyst for biodiesel production via trans-esterification reactions in order to provide cost-effective methods of enzyme recycling. The efficacy of the immobilized enzyme catalyst at low loading (6.2 wt %) and the effects of temperature, water content, and reaction time in model trans-esterification of glyceryl trioctanoate were investigated extensively. It was found that water was necessary for the reaction of glyceryl trioctanoate with ethanol to proceed. A high conversion of glyceryl trioctanoate (∼70%) was obtained at 35 °C, with only 5.0 wt % of water content over a reaction period of 12 h.
