How does carbon deposition on catalytic cracking catalysts affect fluidization performance?
Thread Content
I would like to ask the experts: if carbon builds up on the catalytic cracking catalyst, does this improve or worsen the fluidization effect on the raw material inclined tubes?
Catalyst carbon deposition leads to an increase in bulk density, deteriorates the fluidization effect, and requires more fluidizing medium.
The particles become larger, resulting in a poor flow pattern
The carbon buildup in the regenerator should have little impact on the raw riser.
