Beyond Haber-Bosch: The renaissance of the Claude process

Ammonia may be one of the energy carriers in hydrogen economy. Although research has mostly focused on electrochemical ammonia synthesis, this however remains a scientific challenge. In current article, we discuss feasibility single-pass thermochemical synthesis as an alternative to high-temperature, high-pressure Haber-Bosch loop. We provide overview recently developed low temperature catalysts, well solid sorbents. show that temperature, pressure process can produce at lower cost than loop for small-scale (<40 t-NH3 d?1).
