FREQUENTLY ASKED QUESTIONS

 

What is made under the CATACELJM brand?

CATACELJM shapes special metal foils into a variety of geometries, then coats the foils with different catalysts designed to enable specific reactions within specific environments. The resulting shaped and coated foils are used within components that enable combustion, catalytic partial oxidation, fuel reforming, tail gas combustion, gas-to-liquid, de-sulphurization, hydrogen production via steam methane reforming, and carbon capture processes. Such components are commonly used in fuel cells, syngas and industrial gas applications.


Who uses CATACELJM products?

CATACELJM is supplied to organizations such as fuel cell manufacturers, hydrogen plant builders, onsite hydrogen plant operators, liquid natural gas producers, government agencies and research labs developing and commercializing new energy and hydrogen technologies. We also supply academic research facilities with specialized hardware to augment the development of various energy technologies.


What makes using metal foil as a catalyst support structure particularly desirable?

Thin metal foil offers remarkable advantages over traditional materials. Thin metal foil is lightweight and ductile, can be formed into an array of geometries, provides a large amount of surface for catalytic partial oxidation and other catalytic reactions, is very durable and operates up to 900 degrees C. Most importantly, thin metal foil transfers heat efficiently. CATACELJM foils and designs are very thermally efficient, facilitating heat transfer to adjoining surfaces or structures. This heat exchange provides an increase in efficiency for many traditional processes.

 

How does Johnson Matthey bond CATACELJM catalysts to the metal foil?

This process is at the heart of the CATACELJM patents and trade secrets and is proprietary information. However, it is completely fair to say that no company has more expertise in coating metal foil surfaces for long-lasting operation with catalysts than Johnson Matthey.

 

What are the advantages of using metal foil structured materials?

Johnson Matthey CATACELJM reaction materials are favoured for applications that require long service life, compact system design and/or a high degree of component integration, optimum throughput of feed stock, sustained pressure drop over service life, capability to sustain steady state operations or frequent duty cycles, and optimum reaction efficiency.  In these ways and more, CATACELJM technology can intensify a broad range of fuel processing, combustion and gas separation reaction, and so deliver important value to system designers and operators.


Why are the CATACELJM foil materials frequently corrugated?

Corrugation and other precision shaping operations allow foil surface area to be maximized within a given space. More catalyst can be displayed on the foil and thus more catalytic activity can be provided.

 

How many products are in the CATACELJM range?

Through CATACELJM we offer two product brands: CATACELJMSSR for steam methane reforming to produce pure hydrogen; and CATACELJMHEP, a low-cost, heat exchanging catalytic platform used primarily by companies experimenting with fuel cell and fuel reforming prototypes. Beyond the brands are many coated metal strips, fins, annuli, and other structures designed for specific reaction applications, including catalytic partial oxidation.
