Abstract
Apparatus for transferring solid particles to a receptacle comprises a loading tube (2) surrounded at or near its base by a gas supply chamber (7) terminating in a Coanda surface (9). A slot (10) between the outlet from the loading tube (2) and the beginning of the Coanda surface (9) forms a Coanda nozzle. A throttle (3) is preferably fitted in the loading tube (2) to form an annulus (4) down which the particles flow to the slot (10). A gas supply line (8) preferably enters a gas supply (7) tangentially to supply gas to the Coanda nozzle. The apparatus is particularly suitable for loading catalyst into a reactor.
