4. Consumable solid reactor models

4.1 Reactors with non-circulating solids charge

Two scenarios can be envisaged: a perfectly mixed reactor for the homogeneous phase (Carberry reactor), most often used in the laboratory for kinetic measurements on particles in the absence of external diffusional resistance, and the tubular reactor.

• Perfectly mixed fluid

Assuming a solid with a single particle size, the evolution of solid conversion is ensured by a kinetic law that takes into account the initial particle radius R ₀ , the solid conversion rate X...
