Microlith® Reactor Systems

PCI has developed a compact, lightweight and high efficiency catalytic reactor design offering major performance and cost advantages compared to conventional state-of-the-art catalytic reactors.  The advantages of these high heat and mass transfer reactors are derived from an ultra-short channel length substrate structure (Microlith®) combined with advanced catalyst coatings.

microlith screenThe reactors (see example at right) are constructed of a series of very thin and short metal channel (Microlith®) substrates with low pressure drop, enabling design of a high cell density, low thermal mass device which simultaneously lead to a smaller, lighter and higher efficiency catalytic reactor. Both mass transfer and heat transfer are significantly increased by the substrate design, allowing more rapid reactor response to gas temperatures as well as improved rates of reactant contact with the surface. 

Microlith® substrates have several superior attributes, for example, in oxidation reactors:

  • Ultra-compact: equivalent conversion and the same pressure drop as a monolith substrate with a 20 fold size reduction
     
  • Lightweight: Typically 10 times lighter than competing technologies.
     
  • Fast transient response: Typically 30 times faster than ceramic monoliths.
     
  • High geometric surface area: Up to 6 times higher than competing technologies, leading to higher reaction selectivity and performance advantages.

Microlith® technology has been developed with a combination of DOD, EPA, NASA and NSF SBIR R&D programs and joint programs with interested U.S. manufacturers.  This technology has been developed for PEM and SOFC fuel processors, catalytic converters, catalytic burners and combustors, fuel cell and fuel reformer oxidizers, fuel reformer catalytic reactors, air cleaning systems, and chemical reactor applications.  Microlith technology is scalable in many parameters allowing for custom tailored product development to unique individual application requirements.
