Help: What is the full English name of FDFCC DCC?
Finally, the Fle*ble Dual-riser Fluid Catalytic Cracking process was found – abbreviated as FDFCC process: catalytic cracking; deep catalytic cracking; DCC
The catalytic cracking (DCC) process is a new technology that uses heavy distillate oil as raw material, and employs specialized catalytic cracking catalysts to produce large amounts of gaseous olefins under appropriate process conditions. The DCC process is divided into Type I and Type II. The Type I process utilizes a riser-type packed-bed reactor configuration to produce low-carbon gas olefins, with the primary goal of producing propylene in large quantities. The Type II process uses only a conventional catalytic cracking riser reactor, and while incorporating some residue oil, it aims to balance the production of low-carbon olefins and gasoline.
FDFCC usually says: Dual riser catalytic cracking has been discussed on the forum, and someone has also compiled a summary: http://bbs.hcbbs.com/viewthread.php?tid=425383

The FDFCC process technology has evolved through 3 generations: The FDFCC-1 process adds another riser to the FCC unit; the FDFCC-2 process uses a mixture of fresh catalyst and regenerated catalyst in FDFCC-1, thereby adding a mixer; the FDFCC-3 process adds another secondary distillation column to FDFCC-2
