Ammonia Synthesis at Moderate Conditions
Sean-Thomas Bourne Lundin, J. Douglas Way, and Colin A. Wolden
Summary: The synthesis of ammonia at moderate temperatures and pressures
Description: Commercial ammonia synthesis relies on the Haber-Bosch process, which uses a
potassium-promoted iron catalyst in an energy intensive process that occurs at high temperature
and pressures. Because of this, there is substantial motivation to achieve ammonia synthesis at
more moderate conditions. This invention details a method and apparatus for the synthesis of
ammonia at moderate pressures (below 30 atm) and temperatures (400C). A hydrogen
permeable membrane reactor with a porous ruthenium catalyst layer is employed. Further
opportunities exist for process integration of this membrane reactor with other high-
temperature membranes that produce oxygen from air and/or hydrogen from steam and
Main Advantages of this Invention
 Lower production cost
 Reaction proceeds at moderate
 Potential for process integration
 Potential of on-site, scalable
Potential Areas of Application
 Industrial Gas Production Companies
 Fertilizer Companies
