Catalyst АОК-77-25

Process

Hydrotreating of oil fractions

Product Type

Catalyst for removal of sulfur, nitrogen and oxygen compounds from petroleum fractions. Applied in refineries to produce motor fuels with ultra-low sulfur content from medium distillates. Catalyst АОК-77-25 allows to reduce the sulfur content in the fuel to ultra-low concentration (less than 10 ppm).

The catalyst is available in trefoil extrudates with a diameter of 2-3 mm. Also available in quadra lobe shape. The catalyst contains a cobalt-molybdenum or nickel-molybdenum active component.


Application

Catalyst АОК-77-25 is used as a fixed bed and is equipped with protective beds of the PC series. The catalyst can be regenerated 1-2 times during the service life.
