Evaluation of diffusional resistances in the process of glucose isomerization to fructose by immobilized glucose isomerase

A kinetic model presented in a previous work is employed to carry out a systematic study dealing with the relative importance of intraparticle and interparticle diffusional resistances in the process of glucose isomerization to fructose by immobilized glucose isomerase. An analytical generalized expression of the effectiveness factor is obtained, which promises to be particularly useful for design purposes. Finally, the role of each of the main parameters influencing the catalyst effectiveness factor is put in evidence and discussed within the whole range of possible operative conditions.
