A Mathematical Model for Coupled Gas-Solid Reactions in a Reacting Gas Atmosphere

Abstract

A mathematical model has been proposed for describing the coupled gas-solid reactions in a reacting gas atmosphere. Effects of the following five parameters on the conversions of solids B and D have been examined: reaction/diffusion ratio, Sherwood number, reactivity ratio, factors of catalytic activity and reactant amount ratio. The conversion of solid B was found to be able to be increased by reducing the pellet size, increasing the relative initial amount of solid D to solid B, or increasing the velocity of bulk gas.
