Operating envelope of Haber–Bosch process design for power-to-ammonia [PDF]

RSC Advances, 2018
The Haber–Bosch process is viable for power-to-ammonia, as it can be operated for a wide range of the operating envelope while maintaining the process variables' operational, hydrogen feed intake and ammonia production flexibilities.

Liquid Sorption-Enhanced Haber–Bosch Process [PDF]

Industrial & Engineering Chemistry Research
The use of a liquid sorbent in a traditional Haber-Bosch process enables significant improvements in energy efficiency and potential cost savings for arguably the most important chemical process on the planet. The approach presented in this report employs an incompressible liquid sorbent that absorbs and releases ammonia (NH3) under specific conditions.

Operando probing of the surface chemistry during the Haber–Bosch process [PDF]

Nature
AbstractThe large-scale conversion of N2and H2into NH3(refs. 1,2) over Fe and Ru catalysts3for fertilizer production occurs through the Haber–Bosch process, which has been considered the most important scientific invention of the twentieth century4. The active component of the catalyst enabling the conversion was variously considered to be the oxide5 ...

Achieving volatile potassium promoted ammonia synthesis via mechanochemistry

Nature Communications, 2023
Potassium oxide (K2O) is used as a promotor in industrial ammonia synthesis, although metallic potassium (K) is better in theory. The reason K2O is used is because metallic K, which volatilizes around 400 °C, separates from the catalyst in the harsh ...

Construction of C/MoS2 nanocomposite for highly efficient electrocatalytic NRR [PDF]

E3S Web of Conferences, 2021
Electrochemical N2 reduction reaction (NRR) has been considered as a promising and green process to replace conventional Haber−Bosch process. However, the presence of sluggish reaction kinetics and competitive hydrogen evolution reaction (HER) can result
