Techno-economic performances and life cycle greenhouse gas emissions of various ammonia production pathways including conventional, carbon-capturing, nuclear-powered, and renewable production

Green Chemistry, 2022
Ammonia (NH3) is conventionally produced using fossil natural gas (NG) for hydrogen production through steam reformation, and synthesis in Haber-Bosch (HB) process.

Experimental study on nitrification in a submerged aerated biofilter [PDF]

, 2004
The aim of the present work was to evaluate the performance of a semi-pilot scale BAF in order to obtain a highly polished effluent in terms of removal of organic matter, suspended solids and ammonia and to observe the influence of temperature, pH and ...

Coordinative Stabilization of Single Bismuth Sites in a Carbon–Nitrogen Matrix to Generate Atom‐Efficient Catalysts for Electrochemical Nitrate Reduction to Ammonia

Advanced Science, 2023
Electrochemical nitrate reduction to ammonia powered by renewable electricity is not only a promising alternative to the established energy‐intense and non‐ecofriendly Haber–Bosch reaction for ammonia generation but also a future contributor to the ever ...

Effect of the ammonia concentration on the performance of wetland microbial fuel cells [PDF]

E3S Web of Conferences, 2021
This work explores the effect of the ammonia concentration on the wetland synthesis of microbial fuel cell (MFC) and on the production and the efficiency of sewage purification. Four ammonia concentrations from 1 to 30 mg/L have been selected.

Synthesis and methane cracking activity of a silicon nitride supported vanadium nitride nanoparticle composite [PDF]

, 2017
The co-ammonolysis of V(NMe2)4 and Si(NHMe)4 with ammonia in THF and in the presence of ammonium triflate ([NH4][CF3SO3]) leads to the formation of monolithic gels.

Dynamic Simulation Analysis and Optimization of Green Ammonia Production Process under Transition State

Processes, 2022
Ammonia is an important chemical raw material and the main hydrogen energy carrier. In the context of “carbon neutrality”, green ammonia produced using renewable energy is cleaner and produces less carbon than traditional ammonia production. Raw hydrogen

Ammonia Production as Alternative Energy for the Baltic Sea Region

Energies, 2023
One of the consequences of the conflict in Ukraine relates to the growing shortfall in global ammonia production. There are additional negative global impacts on the availability of fertilizers and prices of ammonia (NH3).

Broilers' head behavior as an early warning index of production and lung health under ammonia exposure

Poultry Science, 2021
This study investigated the effects of ammonia exposure (0, 15, 25, and 35 ppm) on head behavior, production performance and lung tissue morphology of broilers, and the relationship between head behavior, production performance, and lung tissue injury ...

Nitrogenase: A nucleotide-dependent molecular switch [PDF]

, 1994
In the simplest terms, the biological nitrogen cycle is the reduction of atmospheric dinitrogen (N2) to ammonia with the subsequent reoxidation ammonia to dinitrogen (1).
