Abstract
Fines are removed from a fines-containing fluid by fluidizing a bed of fluidizable solids with the fines-containing fluid at conditions avoiding fluid spouting at the bed surface, the bed solids being preferably at least two orders of magnitude greater in size than the particles, and being coated with a substance whose stickiness changes during its residence time in the bed. Particles adhere to the transiently sticky solids and can be recovered for re-use. Useful for cleaning dusty gases and recovering catalyst from cracker flue gas.
