As sulfur legislations tighten, it becomes more difficult for refiners to meet the specifications from their FCC gasoline post-treatment units. Particularly the octane number poses challenges, since some olefins are simultaneously being hydrogenated. The consequent loss of octane often prevents the refineries from achieving maximum value.
Topsoe’s series of HyOctane™ catalysts are specifically developed for all steps in FCC gasoline post-treatment applications. Their optimized activity and selectivity enable removal of sulfur to ultra-low levels while retaining high octane numbers, allowing a stable, flexible and profitable production of high quality gasoline.
