Ammonia Synthesis Membrane Reactor

The Colorado School of Mines will develop a membrane reactor concept to synthesize ammonia at ambient pressure. In traditional ammonia production processes, nitrogen (N2) and hydrogen (H2) compete for identical catalyst sites, and the presence of each inhibits the other, with the overall rate reflecting a compromise. The team proposes decoupling and independently controlling the N2 and H2 dissociation by dedicating one side of the composite membrane to each. In this way, the catalysts may be individually optimized. Highly effective catalysts have been previously demonstrated for H2…
