Abstract

Traditional ammonia cracking is achieved at 850-950C in the presence of a nickel catalyst. The reaction is highly endothermic, and maintaining these high temperatures at high flow rates of ammonia gas can be difficult. Here, we present work using our advanced ammonia synthesis catalyst in an ammonia cracking setup. We use a metallic monolith catalyst support to minimize pressure drop at high flow rates. Full NH3 cracking occurs at 600C, with the onset of cracking at 400C. An output flame can be achieved with a fully tunable ratio of hydrogen to ammonia, depending on the temperature setpoint of the cracker.
