摘要
介绍了多产丙烯和异丁烯催化裂化FLOS-Ⅲ助剂在中国石化巴陵分公司1.05 Mt/a MIP-CGP催化裂化装置的首次工业应用情况。标定结果表明:在多产丙烯与异丁烯催化裂化助剂FLOS-Ⅲ占系统催化剂藏量的6%时,液化气产率比空白标定时增加2.68百分点,其中丙烯产率增加1.01百分点,异丁烯产率增加0.54百分点;产品分布明显改善,品质差且附加值低的催化裂化柴油产率下降2.09百分点,焦炭产率下降0.25百分点,总液体收率增加0.17百分点;汽油产率及汽油RON与空白标定时相当,其它产品性质相当;使用FLOS-Ⅲ助剂可实现增产丙烯和异丁烯的目的,经济效益显著。
The application of catalytic cracking additive FLOS-Ⅲfor more propylene and isobutene in a 1.05 Mt/a MIP-CGP FCC unit of Baling Petrochemical Company was described.The first application shows that when the inventory ratio of the additive reaches 6%,the yield of LPG,propylene and isobutene increases by 2.68 percentage points,1.01 percentage points,and 0.54 percentage point,respectively,with improved product distribution.The yield of the poor quality and low added value LCO decreases by 2.09 percentage points,the coke yield decreases by 0.25 percentage point,while the total liquid yield increases by 0.17 percentage point.The yield of gasoline and its RON is similar to the blank test.It is concluded that the use of additive FLOS-Ⅲis helpful to produce more propylene and isobutene with significant economic benefits.
