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)
