• Sequential processing of
different feedstock in multizone
catalytic cracking in single riser
depending on cracking behavior
of hydrocarbon
• Also process high coke-making
feedstock like residue, slurry oil,
etc. at the upper end of the riser
and then burn off the coke, thus
produced in separate regenerator
to satisfy the heat balance
requirement
