A study was conducted using a series of FCC catalysts that included reduced rare-earth content and increased zeolite Y quantity systems. The goal was to raise gasoline yield along with greater yields of olefins.
At Gazpromnefts Moscow refinery, the fluid catalytic cracking (FCC) unit had the potential to increase throughput with a catalyst-to-feed mass ratio of 4. A study was conducted using a series of FCC catalysts that included reduced rare-earth (RE) content and increased zeolite Y quantity systems. The goal of the catalyst study was to increase gasoline yield, along with greater yields of olefins (C3 and C4) from the FCC unit, as the catalyst-to-feed mass ratio was steadily reduced from 5.7 to 4.5.
During this catalyst evaluation process, no extensive modernization of the existing FCC equipment was required. The main driver for the project was an informed effort to switch from RE
