» 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 support’s 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
