COMMERCIAL APPLICATION OF MULTIFUNCTIONAL LIGHT OLEFIN-BOOSTING ADDITIVE COMP IN CATALYTIC CRACKING UNIT

Abstract

Abstract: The first commercial application of COMP additive for boosting lighe olefins in a catalytic cracking unit with capacity of 1.8 Mt/a is introduced. The COMP additive accounts for 8% of the inventory. Compared with the blank test, the yield of LPG and propylene increased by 2.50 and 1.35 percentage points, respectively, the yield of gasoline decreased by 2.11 percentage points, the yield of diesel and slurry oil decreased by 0.55 and 0.20 percentage point, respectively, furthermore the selectivity of coke decreased by 0.13 percentage point. The results indicate that the unit achieved the trial target of and significant economic benefits after COMP additive application.

Key words: catalytic cracking, light olefin, multifunctional addtive, propylene
