Fluidized Bed Reactors Visual Encyclopedia of Chemical

Equipment Design. Before the reactor is started the catalyst pellets lie on a grate at the bottom of the reactor. Reactants are pumped into the reactor through a distributor continuously, causing the bed to become fluidized. The bed's behavior after initial fluidization depends on the state of the reactant.
