  • Descrição: The esterification of fusel oil with oleic acid catalyzed by lipase from Rhizopus oryzae immobilized on polystyrene/divinylbenzene copolymer resin was assessed in a two-stage packed bed reactor running on a continuous flow. Molecular sieves were used to remove the water formed as byproduct by coupling the reactor with a column extractor. The modification presented herein introduces a pathway for replacing saturated molecular sieves by regenerated sieves at a given time. Ester synthesis on a continuous flow carried out without a water column extractor was used as a control. The performance of the proposed system was quantitatively confirmed for space-times of 10 h, thus resulting in average productivities of 292.2 ± 18.5 molester g-1 min-1, with minimal feedstock lost and good stability of the immobilized lipase, revealing an average half-life time of 179.6 h.
