KINETIC-STUDY OF THE FRUCTOSE GLUCOSE ISO MERIZATION IN A FIXED-BED REACTOR AT 50-DEGREES-C

It has been studied the fructose to glucose isomerization using a fixe d bed reactor and recirculation with a commercial enzyme, the inmovili zed glucose isomerase at a temperature of 50-degrees-C. The kinetics o f the isomerization corresponds to a pseudofirst order reversible enzi matic reaction. It has been estimated the effectiveness factor for int ernal materia transfer that seems to be independent of the used substr ate concentrations, being the external materia transfer disregarding a t the flows considered.
