Resumen:
A recently developed technique to estimate effectiveness factor in catalytic pellets [J.C. Gottifredi, E.E. Gonzo, On the effectiveness factor
calculation for a reaction-diffusion process in an immobilized biocatalyst pellet, Biochem. Eng. J. 24 (2005) 235242] is used to greatly simplify
the simulation of membrane biocatalyst reactors. The whole problem is reduced to well-known plug flow packed bed reactor after an appropriate
definition of an effectiveness factor (ç) that takes into account chemical consumption in the catalytic region and mass transfer resistances of the
reactive component. A standard RK routine can then be applied since, at each mesh point, ç is calculated through a non-linear algebraic equation.
Results produced with this procedure compare fairly well with previous findings. Moreover some experimental results of kinetics studies related
with enzyme immobilization are used to simulate membrane hollow fiber reactors and conversion, concentrations and ç profiles along reactor axial
position.
The procedure can be applied to any biocatalytic system provided a single chemical reaction takes place although the kinetic expression can be
arbitrary.ç) that takes into account chemical consumption in the catalytic region and mass transfer resistances of the
