Reactions with consumable solids
Calculation of fluidized bed reactors

Consumable solids are those which react directly with the gaseous reagent.

There are two types of reactions with consumable solids:

• those which produce a gaseous product, leading to a decrease in particle size as the reaction progresses (figure 6 a );

• those that result in the formation of a solid product on the particle surface, without any appreciable change in particle size (figure
