Active top layer media

We supply a complete range of activated products as top grading media to trap catalyst poison. The main advantage of the MTE standard grading materials is the use of regenerated catalyst for the low active grading materials. The CoMo and NiMo active top grading is a cost-effective product for slow removal of the most reactive feed components. Mainly the regenerated catalyst products are produced in spherical or cylindrical rings shapes. We have our own supply chain for regenerated catalyst, but it is also possible to supply your own material, to be used as raw material.


  • Naphta Hydrotreating (NHT)
  • Distillate Hydrocracker (DHC)
  • Hydrodesulfurization (DHS)
  • Hydrodenitrogenation (HDN)


Capture of catalyst poisons like:

  • Arsenic (As)
  • Silica (Si)
  • Vanadium (V)
  • Iron (Fe)
  • Capture of salts like Sodium (Na)

On request, MTE can make NiMo and CoMo top grading catalyst in any required activity, based on required specifications. We can produce grading materials in any shape, including spheres, cylindrical rings, trilobes, quadralobes or any other extruded shape.
