The animation below shows the operation of a moving-bed reactor. Reactants (green) and catalyst (white) enter the top of the reactor and move through the vessel. Once at the bottom the catalyst (black) is removed and regenerated; products (blue) are removed from the reaction system and the catalyst is regenerated and brought to the top of the reactor.
This animation shows the basic operation within a moving bed reactor. Solid catalyst pellets are continuously introduced at the top of the reactor, as are the fluid phase reactants. The catalyst and the fluid flow together down the reactor. The reaction takes place along the way, which establishes a concentration gradient.
