Three types of zone-reaction models representing reactions between porous solid and gas are compared. When the diffusion of gaseous reactant affects the overall reaction rate, the reaction proceeds at the core surface. By introducing the concept of an equivalent rate constant, &, based on the surfac
This work presents a novel numerical gas-solid reaction model which is based on the mass and the heat transport in the pellet. The initial nonporous pellet is transformed into a porous pellet upon the reaction. Due to this transformation, the increased surface of the pellet accompanied by an acceler
