| Abstract: | FDFCC technology utilizes a dual-riser reaction system to control process residue oil and to upgrade FCC gasoline in separate riser reactors under different operation conditions.It can cost-effectively decrease the olefin and sulfur contents in cracked naphtha and enhance propylene yield by the selective control of reactions such as cracking and hydrogen transfer.The results of industry application show that the olefin volume fraction in cracked naphtha dropped to less than 16%,and sulfur mass fraction reduced 22%～24%.The RON and MON increases to 1～2units.Meanwhile the capability of FCC to produce propylene increased by 2%～3%. |
