Project Description

Octane Auxiliary FCC addtive

 

1.1 Product name:

Chemical Chinese name: LSTXA-1 catalytic cracking octane auxiliary, chemical common name or trade name: octane auxiliary, LSTXA-1 catalytic cracking octane auxiliary, chemical English name: Octance enhancing additive.

1.2 Product introduction:

LSTXA-1 catalytic cracking octane adjuvant is a high-efficiency solid adjuvant used in refining catalytic cracking (FCC) units, which can significantly improve the octane number of catalytic cracking gasoline and increase propylene production without affecting dry gas and coke yields , without diluting the activity of the main catalyst, when the additive amount does not exceed 8%, the increase of liquefied gas does not exceed 1 percentage point, and the octane number of FCC gasoline increases by more than 1 unit.
