Can the Worlds Most Polluting Heavy Industries

Sep 23, 2021 The Haber-Bosch process uses an iron catalyst. But ever since its invention, the game has been on to find something that works efficiently at lower temperatures and pressures. Tackling low-temperature ammonia synthesis is one of those holy grails of chemistry, says Levi Thompson , a chemical engineer at the University of Michigan.

INVESTIGATING REDOX CHEMISTRY OF GRAPHITE IRON

The Haber-Bosch process uses nitrogen (N2) and hydrogen (H2) over iron surfaces to produce ammonia (NH3) at high pressures (100-200 atm) and high temperatures (400-500C). We investigated the rate-limiting step, the dissociation of N2, on a Fe3O4(001) surface, to determine the chemical changes near ambient pressures.

Investigation of N2 adsorption on Fe3O4001 using ambient

Feb 06, 2020 Reactions on iron oxide surfaces are prevalent in various chemical processes from heterogeneous catalysts to minerals. Nitrogen (N 2) is known to dissociate on iron surfaces, a precursor for ammonia production in the HaberBosch process, where the dissociation of N 2 is the limiting step in the reaction under equilibrium conditions. However, little is known about N 2
