Abstract
The application of an immobilized lipase for the interesterification of lipids in a continuous solvent-free system has been studied. Important engineering parameters which are necessary for the design of a bioreactor e.g. a fixed bed reactor has been examined. The pressure drop across a fixed bed (Hp= 0,7 m; T = 60 °%; Ug = 7° 10 74 m/s) was 0,5 bar. The flow of the substrate through the biocatalyst bed can be described by a linear equation. The influence of internal and external mass transfer limitations on the conversion of the reaction has been tested in stirred tank reactors and fixed bed reactors. The reaction rate is influenced by internal diffusion effects. Film diffusion limitations can be neglected for flow rates over 8,0 + 10 "° ms.
