Abstract
Process and device for the transport of granular solids with a controlled flow rate, in particular for the transport of catalyst in a hydrocarbon reforming unit. The device comprises a gravity-feed pipe (A) for solid particles in the dense phase, a pneumatic transport pipe (C) in the dilute phase, and an inclined transfer pipe (B) that connects, without a buffer space, the base of the feed pipe to the pneumatic transport pipe, whereby this transfer pipe comprises means () for injection of a secondary gas located at the junction between the feed pipe and the transfer pipe.
