摘要： A fluidized-bed seal, formed by a vertical vessel divided with a baffle into two parts, closed at the upper end and having a fluidization grid situated at the lower end of the vessel, two vertical pipes which extend into the upper part of the vessel for inlet and outlet of particles and two pipes situated in the upper part of the vessel for inlet of secondary fluid, the cross sectional area of the fluidization grid being from 30 to 100% of the cross sectional area of the upper part of the vessel. The pipes for the inlet and outlet of particles extend into the upper part of the vessel from one to about three diameters of the pipes. The fluidized-bed seal can be used for continuous transport of cracking catalyst into the fluidization reactor.
