What type of transportation does the catalyst in the riser use?
Thread Content
The device is coaxial; is the catalyst in the lift pipe transported in a dilute phase or a dense phase? What is the approximate density? I hope to receive guidance from all the teachers!
Lean-phase transport, with a density of less than 100 kg/m³

It relates to dilute-phase transport; the riser acts as a transport bed, as increasing the catalyst circulation rate is not sufficient to maintain the bed layer – the system has reached a state of pneumatic transport, hence it is a transport bed.
How do you know your density? 100?
The pre-lift section is the interface between the dilute and dense phases
