Collocation Analysis of Multicomponent Diffusion and Reactions in Porous Catalysts.

Abstract:

A collocation method is given for steady-state simulation of multiple reactions in porous catalysts. A realistic multicomponent diffusion model is used, which includes an allowance for pore size distribution. Hyperbolic basis functions are introduced to represent the intraparticle profiles compact solutions are thus obtained both in the presence and absence of fast reactions. Calculations for a six-component catalytic reforming system show that the catalyst performance is strongly affected by intraparticle diffusion. Author
