Improving the Energy Yield of Plasma-Based Ammonia Synthesis with In Situ Adsorption

Plasma-based ammonia synthesis is studied as an option for electrifying the chemical industry. However, energy efficiency of plasma-based severely limited by decomposition in plasma phase. We show that use zeolite 4A adsorbent situ removal from phase suppresses product decomposition, thereby increasing yield. It found yield plasma-chemical with improved a factor 2 compared to steady-state synthesis. Plasma-induced surface heating limits effective adsorption capacity zeolite, decreasing capacity. In interest chemistry and catalysis, general, general phenomenon limiting
