Advanced Catalyst Manufacturing Enabled by Direct Joule Heating

05/2020, ARPA-E

Ammonia synthesis reactions, enabled by the Haber-Bosch process, account for approximately 3% of the world’s total energy use. HighT-Tech propose a cascade reactor with a sequence of non-platinum group metals catalyst compositions tailored to a specific stage of the synthesis reaction.

HighT-Tech's novel, direct Pulse Heating process enables the synthesis of high entropy alloy nanoparticles with various catalyst compositions. This method will produce ammonia synthesis catalysts that deliver more ammonia per pass and require significantly less capital cost and energy to operate.
