Zusammenfassung
The aim this work was investigated a new route for biodiesel production
using immobilized lipase from Candida antarctica in continuous Fluidized
Bed Bioreactor. Conventionally, Biodiesel (fatty acid methyl esters) is
produced by transesterification in which, oil or fat is reacted with a
monohydric alcohol in presence of a catalyst. In recent years, the use
of lipases as biocatalysts for biodiesel production has become of great
interest due to its environment friendly. But some alcohols such as
methanol inactivated the lipases to some extent and the enzymatic
stability was poor. In order to enhance the stability of the lipase,
three-step methanolysis was adopted, however, glycerol, as one of the
products was easy to adsorb on the surface of lipase resulting in
serious negative effect on the enzymatic activity. For to solve problems
was used the interesterification kinetics of triglycerides and methyl
acetate for biodiesel production was modeled. A heterogeneous model
describing the interesterification process in an immobilized enzyme
fluidized-bed bioreactor was developed. A simplified model based on Ping
Pong Bi Bi with substrate competitive inhibition mechanism was proposed
to describe the reaction kinetics of the interesterification. The model
without any adjustable parameters was used to predict the
interesterification process. The key parameters which measured the
extent of external and internal mass-transport resistances, as well as
the degree of back-mixing were quantified and discussed. The
fluidized-bed bioreactor considered in this investigation is composed of
two phases: a fluid phase comprised mainly of the triglycerides and
methyl acetate and the product (Biodiesel); and a solid phase which is
the immobilized enzyme. The effects of some operating and design
parameters on the performance of the fluidized-bed bioreactor were also
analyzed. The model was also tested for its sensitivity to changes in
hydrodynamic parameters.
