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.

The development of low-temperature, nonprecious metal thermocatalysts for ammonia decomposition holds significant promise advancing the green hydrogen industry. LaNiO3 catalysts, with their perovskite structure (ABX3), are notable enabling in situ growth active Ni on reduced oxide supports during reactions (ADRs). However, unintentional can lead to uncontrolled and particle agglomeration. To address this, we employed a straightforward high-temperature pressure hydrogenation pretreatment process enhance interaction between support, thereby suppressing agglomeration ADR process. Our results indicate that catalyst exhibits finer nanoparticles, an average size approximately 8 nm. Under gas hourly space velocity (GHSV) 18,000 mL gcat–1 h–1 at 550 °C, NH3 conversion efficiency reaches 90%, which exhibited excellent stability over period 100 h. Additionally, utilized TEM, XPS, EPR, NH3-TPD, H2-TPR techniques elucidate intrinsic mechanisms related enhanced catalytic activity. This study addresses issue nanoparticle through pretreatment.
