Abstract
A process and apparatus is disclosed for gradually starting fluidization in a bed of particulate from the top down so as to avoid thrusting the entire mass of particulates upwardly in the bed at the same time which may damage internals in the bed. The particulate bed may comprise a catalyst cooler for an FCC unit containing internals such as cooling, fluidization and support equipment.
