Catalysts

COMESSA works closely with leading contractors and licensors for equipment ranging from pilot size up to industrial size.

Since the 1950s, COMESSA has been working with all major worldwide players in this field of activity (end users, engineering companies and licensors), offering custom-built, reliable, heavy duty and efficient solutions for thermal processing of catalysts.

With its thorough expertise in low- and high-temperature catalysts processing under controlled atmosphere (air, nitrogen, hydrogen, etc.), COMESSA offers complete solutions for various stages of their preparation:

  • Drying
  • Dehydratation
  • Activation
  • Reduction
  • Regeneration
  • Gas/solid reaction
  • Calcination
  • Cooling

Depending the process, COMESSA is able to offer different following solutions:

  • High temperature fluidized bed reactors with/or agitator
  • Indirectly heated rotary tubes
  • Vibrating fluidized beds
  • Static fluidized beds
  • Band dryers

Choice of the most suitable equipment depends on the nature and type of catalyst to process, as well as the process sought.

Our strengths:

  • Control of cycle and homogeneous of the process
  • Custom-built equipment
  • High temperature experience up to 950 °C
  • Thermal optimization & Energy efficiency
  • Pilot tests laboratory
  • Process under controlled atmosphere
