The effects of the compostion s of different catalytic stocks on catalytic cracking reaction was discussed.
After the cracking reaction in downflow reactor, reaction products are separated and spent catalyst is directed to stripping and regeneration sections.
The EDC cracking reaction rate is higher in the wall zone and reaches a maximum at 0.3 of dimensionless length of reactor coil.
The mechanism of coupling catalytic cracking reactions and aromatization reactions was briefly discussed.
