Apparatus which has particular utility in the transfer of particulate solids out of a fluidized bed, comprises means for keeping a bed of particulate solids in a fluidized bed mode in a vessel, a conduit for transferring the particulate solids into the resulting fluidized bed and a standpipe, protruding into the fluidized bed, for transferring particulate solids out of the fluidized bed; the upper part of the standpipe comprises an inlet for receiving particulate solids from the fluidized bed, the inlet is located close to the bottom wall of the vessel such that, when in use, the bottom wall induces a local partial de-fluidization, resulting in a local dense fluidization zone thereabove, near the proximity of the inlet of the standpipe; and the inlet in the upper part of the standpipe comprises a plurality of openings cut through the wall of the standpipe below the upper end and above said bottom wall.
