| Annotation | A mathematical model of n-hexadecane hydroisomerization over a bifunctional zeolite catalyst is considered. The model includes a lumped kinetic scheme, a stationary diffusion–reaction problem in a cylindrical catalyst pellet, and calculation of reaction effectiveness factors. The proposed approach makes it possible to relate experimentally determined apparent rate constants to intrinsic kinetic parameters and to evaluate the influence of structural and diffusion characteristics of the catalyst pellet on process performance. Based on the developed model, a multiobjective optimization problem is formulated with respect to temperature and contact time. |
