  • Improved promotion The occurrence of inactive species

    on the catalyst surface is minimized.

    Thus, more Cobalt or Nickel atoms

    are available for incorporation into

    the edges of MoS2 slabs. More metal

    atoms in MoS2 edges, by definition,

    means an increased amount of mixed,

    highly active sites.

    Improved dispersion

    Schematic representation of the dispersion phenomenon. With the

    same number of atoms, Impulse MoS2

    slabs have more active sites

    (red arrows).

    Improved support characteristics

    The supports pore diameter distribution was tightened around an

    ideal diameter, ensuring maximum

    activity towards refractory species.

    Furthermore, interactions between

    the carrier and the active phase were

    optimized so as to maintain good

    stability throughout operation.

    A breakthrough technology... ...For maximum refinery profits

    More difficult feedstocks without cycle penalty

    Maximum throughput with higher end boiling points

    Longer cycles
