STUDY OF ACTIVITY DISTRIBUTION FOR CONSECUTIVE REACTIONS

The optimal pellet activity distribution for a system of consecutive r eactions is analyzed numerically. Two cases are studied: the case of u nconstrained activity (without predescribed maximal concentration of a ctive component) leading to a Dirac delta activity distribution and th e case with upper bound for the activity distribution (concentration o f active component can not exceed given maximal value) which leads to a step function profile. As the objective function global selectivity is chosen. Examples of both cases are given. The reaction kinetics is described by Langmuir-Hinshelwood type of equations.
