RFCC and FCC! !
Thread Content
I would like to ask what the full names of RFCC and FCC are? What’s the difference? Additionally, what is the difference between strong catalysts and weak catalysts? What are the main components of each type of catalyst? Thank you! ! !

Heavy oil contains a high amount of catalyst contaminants, and it tends to coking more; therefore, catalysts with good cracking properties and resistance to contamination are required
The coking amount in the regenerator is high under intense heating, so a heat removal device must be installed. The quality of the feedstock is poor, usually consisting of residue components; while in mild catalysis, it generally involves the catalytic cracking of fractionated oils~~~
Heavy oil catalytic cracking, Paraffin oil catalytic cracking～
Wax oil is catalytically processed with distillate oil, while heavy catalysis is used for residue; the products are similar, but there are differences in yield and quality. Heavy catalysis produces more coke and impurities, requiring more heat for regeneration. Products: dry gas, liquefied gas, gasoline, diesel, catalytic slurry
DCC Deep Catalytic Cracking refers to deep catalytic cracking, that is, catalytic pyrolysis
