摘要：
Particle-pellet approach was used for the analysis of selectivity in a consecutive reaction scheme. It was illustrated that the ratio of macro and micropore diffusion resistance (<y) has a significant effect on selectivity especially for intermediate values of particle Thiele modulus. Increase of this ratio and increase of particle Thiele modulus yield lower selectivities for the intermediate product. © 1991, Taylor & Francis Group, LLC. All rights reserved.
