Demagnetizing Ferromagnetic Catalysts to the Sabatier Optimal of Haber–Bosch Process
JACS Au, 2023 Achieving the Sabatier optimal of a chemical reaction has been the central topic in heterogenous catalysis for a century. However, this ultimate goal is greatly hindered by the extrinsic modifications in previous catalyst design strategies. Accord-ing to the magneto-catalytic effect (MCE), the performance of ferromagnetic catalysts can be promoted ...

Beyond Haber-Bosch: The renaissance of the Claude process
International Journal of Hydrogen Energy, 2021 Ammonia may be one of the energy carriers in the hydrogen economy. Although research has mostly focused on electrochemical ammonia synthesis, this however remains a scientific challenge. In the current article, we discuss the feasibility of single-pass thermochemical ammonia synthesis as an alternative to the high-temperature, high-pressure Haber-Bosch

An Electrochemical Haber-Bosch Process [PDF]
Joule, 2020 Summary Ammonia, produced via the Haber-Bosch (HB) process, is globally the leading chemical in energy consumption and carbon dioxide emissions. In ammonia plants, hydrogen is generated by steam-methane reforming (SMR) and water-gas shift (WGS) and, subsequently, is purified for the high-pressure ammonia synthesis.

Angewandte Chemie - International Edition, 2013 Ammonia synthesis is one of the largest processes in chemical industries. It was first operated at BASF one hundred years ago based on the fundamental work of Fritz Haber and process engineering by Carl Bosch. Haber combined feed gas recycling with application of high pressure (P = 200 bar) and a Ruthenium catalyst to achieve sufficiently high ...

Production of Ammonia from Low Rank Coal Employing Chemical Looping and Haber-Bosch Process
Chemical Engineering Transactions, 2017 An integrated production system of ammonia from low rank coal (LRC) is proposed and evaluated in this study. It unites several processes: coal direct chemical looping, nitrogen production, ammonia synthesis, and power generation. To effectively integrate

(Ru-)Mo2C (MXene) catalysts for ammonia synthesis: From Haber-Bosch to chemical looping processes
Materials Today CatalysisThis study investigated (Ru-)Mo2C (MXene) materials for ammonia thermo-catalytic synthesis under atmospheric or moderate pressure. Under a H2-N2 (3:1) flow, the Mo2C MXene phase showed limited activity in ammonia synthesis at atmospheric pressure at 400 °

Beyond Soil Inoculation: Cyanobacteria as a Fertilizer Replacement
Nitrogen, 2023 Nitrogen-fixing bacteria such as cyanobacteria have the capability to fix atmospheric nitrogen at ambient temperature and pressure, and intensive cultivation of cyanobacteria for fertilizer could lead to its use as an “environmentally friendly ...

High-throughput screening of suitable nitrogen carriers for chemical looping ammonia synthesis
Applications in Energy and Combustion Science, 2023 Chemical looping ammonia synthesis is a promising pathway to synthesise ammonia with lower energy and economic costs than the current Haber-Bosch process, for example, by lowering the operating temperature and/or pressure, whilst maintaining comparable ...
