Application : Active Top Bed
Type : Ni, Mo
Shape : Spheres

ACT 645 is used as top bed grading material upstream the main catalytic bed in the hydrotreatment of hydrocarbon cuts including naphtha, gasoil or vacuum gasoil.

ACT 645 acts as an hydrotreatment catalyst and its main purpose is to remove organic iron and organo metalic complexes that could be present in the feed. Its selected carrier, highly porous alumina, provides a very efficient trapping of metals, carbon particles and pollutants of the feed.

ACT 645 can be used in combination with CoMo or NiMo catalysts. The bead shape makes it easy to handle. Its size allow to create a gradient of particle size at the top of the reactor. The attrition resistance is particularly high.

ACT 645 is available under oxide form and has to be sulfided to be active.
