Popis:	In the pnuematic transport systems of catalytic cracking units, use is made of inclined pipelines. This paper studies the conditions of movement of a loose material in inclined delivery standpipes. Characteristic zones in a moving bed of fine-grained materials were determined: a zone of stabilized movement, an outflow zone, a transition zone, and a zone of immobile material. These movements were tested in pipes with various slope angles alpha and different locations of the discharge opening. The results obtained can be used in designing inclined feed standpipes for pneumatic transport systems in catalytic cracking units.
