An innovative process design for ammonia decomposition through reversed plasma catalysis is proposed. Reversed involves a partial thermocatalytic conversion of the feed prior to warm residual ammonia. Lab-scale experiments confirm potential achieve 98.2% using ruthenium-based catalyst in combination with Gliding Arc Plasmatron (GAP). Process modeling reveals an efficiency gain excess heat available from reactor support endothermic cracking. In this study, was compared thermocatalysis and designs under identical conditions, revealing similar energy exergy catalysis. The significant advantage major savings up 60% thermocatalysis. These also reduce size, making promising approach efficient decomposition.

Microkinetic modeling of heterogeneous catalysis serves as an efficient tool bridging atom-scale first-principles calculations and macroscale industrial reactor simulations. Fundamental understanding the microkinetic mechanism relies on a combination experimental theoretical studies. This Perspective presents overview latest progress approaches applied to gas-solid catalytic kinetics. Then, opportunities challenges are presented based recent research in combustion chemistry. For approaches, importance ideal reactors, structured catalysts, precise elementary rate measurements is emphasized. Additionally, integrating spatiotemporally resolved
