Geometry Effects on the Concentration and Reaction Rate Profile in Methanol Production Catalyst. 1. Neglecting External Diffusion

Abstract

In the low-pressure synthesis of methanol from carbon oxides and hydrogen over copper-based catalysts, the effect of catalyst pellet geometry has been investigated. A model for studying reaction within any sufficiently symmetrical porous catalyst particle has been also provided. Fugacity coefficients and compositions are caled, by using the Redlich-Kwong-Soave state equation, and the kinetics model announced by Villa et al. has been used for computing the reaction rates. The reaction is considered to proceed within isothermal and isobaric catalyst pellets. External diffusion has been neglected.
