Most of the countries in the world use gasoline post-treatment for FCC gasoline quality upgrading technology, while the U.S. uses a combination of pretreatment and post-treatment to improve FCC gasoline quality. In the U.S., 50% to 70% of the refineries use FCC gasoline post-hydrotreating technology

This company developed FCC feedstock hydrotreating catalyst (grade KF-907) for the production of clean gasoline meeting Tier III standards. The Ni-Co-Mo trimetallic type pretreatment process for FCC feedstock has been designed for high HDS activity and stability during operation, and is stable under high and low pressure conditions. The catalyst has been used in seven industrial units in the US and Japan.
