✦ Synopsis

Ah&act-An analysis of hollow-fiber enzyme reactors is presented, for first-order kinetics, which leads to explicit expressions for the concentration fields on both the enzyme and substrate sides. These expressions are easily evaluated numerically. Results are presented which show that the substrate-side profiles of bulk concentration versus axial distance can be expressed as functions of a single parameter (an overall mass transfer resistance). Limiting forms of the equations and of system behavior which arise for very low and very high values of the Thiele modulus (corresponding to the reaction-controlled and diffusion-controlled limits) are discussed in some detail. The method of analysis presented is shown to be applicable to other "conjugated boundary value" problems of a similar nature.
