Why Bonnot is #1 Globally for Catalyst Extrusion

It’s no secret that Bonnot has been around a long time. We’re so old, in fact, that we don’t have Articles of Incorporation — they weren’t necessary in 1891. But what most people don’t know is that we started out making machines to process clay. By the early 20th century we transitioned to brick machines, paving roads for cities across the US, and eventually to the wide catalog of extrusion equipment and machines we’re known for around the world today.


The Toughness and Versatility of Bonnot Catalyst Extruders

Bonnot Catalyst Extruders are the industry standard for catalyst processing. Every part of the design is optimally configured for processing abrasive catalyst materials. We choose construction materials that are proprietary to Bonnot and made to last, our engineering enhancements make wearing parts quick and easy to replace. The Bonnot Company revolutionized the Twin Packer design that aids with material ingestion by reducing bridging in the feed hopper. When properly maintained, our catalyst extruders will run for decades.


  • Suitable for ceramics, metals and other catalytic materials
  • Designed to endure the toughest material processing
  • Easy to operate and cost-effective to maintain
  • Utilized by the world’s largest catalyst producers
  • Available with tried and tested trilobe, quadrilobe andcustom catalyst dies

Remember, we’ll always give you proof that your catalyst extruder machine works by allowing you to see it in action in our Test Facility. We have plenty of “tools in the tool bag” to design and manufacture an extruder for catalyst preparation ideally suited for your needs — and your bottom line.
