AIChE Annual Meeting, Topical Conference: NH3 Energy+

ABSTRACT

The most effective ammonia cracking catalysts are currently based on rare metals such as ruthenium and cobalt. While iron can efficiently crack ammonia at 600 °C, it is desirable to develop similarly inexpensive catalysts that are effective at lower temperatures between 350 °C and 500 °C. In this presentation, a new family of imide-based catalysts are described that crack ammonia around 400 °C to 550 °C. These materials do not behave as conventional surface-based catalysts and offer an affordable route for on-board cracking of ammonia for hydrogen fuel-cell cars. The operational parameters of a small 50W lab-based demonstrator will be described and the presentation will conclude with a discussion of the promise of these materials as ammonia synthesis catalysts.
