Systems and methods are provided for using a reverse-flew reactor (or another reactor with flows in opposing directions at different parts of a process cycle) as part of a reaction system for production of ammonia and/or urea. Using a reverse flow reactor as part of an ammonia production process can provide a variety of advantages, including direct heating of the reaction environment, and simplified generation of multiple high-purity reagent streams for ammonia and/or urea synthesis.
