摘要
灵活多效催化裂化技术采用并联双提升管反应器及相应的工艺条件,选择性地控制裂化、氢转移等反应,实现了降低汽油烯烃和硫含量、增产丙烯的目的.工业应用结果表明,该工艺可使汽油烯烃体积分数降低至16%以下,硫质量分数降低22%～24%,研究法和马达法辛烷值分别提高1～2个单位,催化裂化装置的丙烯产率提高2～3个百分点.
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%.
