TK-703 HyOctane™

TK-703 HyOctane™ is a specially developed NiMo catalyst for selective hydrogenation units in Fluid Catalytic Cracking (FCC) gasoline post-treatment. The catalyst has low HDS and hydrogenation activity. Therefore, this catalyst is excellent as a catalyst for the first reactor in FCC gasoline post-treatment units, where only saturation of di-olefins is needed, and the octane loss is minimized. Furthermore, the catalyst enables transfer of sulfur from the light fraction into the heavy fraction of the liquid product.

TK-703 HyOctane™ is part of TOPSOE™’s series of HyOctane™ catalysts that are specifically developed for all steps in FCC gasoline post-treatment applications.

Other catalysts in this series are TK-710 HyOctane™ and TK-747 HyOctane™.

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.


It is applied in Fluid Catalytic Cracking (FCC) gasoline post-treatment.
