FCC catalyst for olefin reduction of heavy oil
fcc@fcccatalyst.net
It has the ability to crack heavy oil and reduce the olefins in gasoline; it has excellent selectivity for LPG and gasoline and good resistance to heavy metal pollution.
Performance characteristics:
Reduce olefins in FCC gasoline by 7 percentage points;
Good gasoline and LPG selectivity;
Good resistance to metal pollution,
Capable of treating high metal content residues that previously required hydrodesulfurization of heavy metals;
Strong heavy oil cracking capacity, high liquid product yield;
The equilibrium catalyst has good thermal stability and high equilibrium activity.
