Batch process versus a continuous processes for manufacturing chemical products. A batch process in chemical manufacturing is where the reactant chemicals (raw materials/feedstock) have to be mixed in a reactor vessel or furnace etc. When the reaction is completed as far as it will go, the product is then extracted.
Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. This allows for extensive mixing in all directions. A result of the mixing is excellent temperature stability and increased mass-transfer and reaction rates. Fluidized bed reactors are capable of handling large amounts of feed and catalyst.
