Selective Non‐Catalytic Reduction of NOx in the Exhaust Gas of Small Wood Gasification Boilers

Chemie Ingenieur Technik, EarlyView.
Kinetic studies of the SNCR reaction were conducted to investigate NOx reduction in the exhaust gas of small‐scale wood gasification boilers. Both the experimental results and the derived global kinetic model indicate that SNCR can achieve a significant reduction in NOx emissions under typical operating conditions. ABSTRACT The gas‐phase reaction of NO

Impact of Trace Water on the Macroscopic Activity of Commercial Ammonia Cracking Catalysts Under Process‐Relevant Conditions

Chemie Ingenieur Technik, EarlyView.
This study evaluates how small water impurities—typical in ammonia cracking feedstock—affect catalyst performance at elevated pressures and temperatures. By decoupling permanent degradation from reversible inhibition, the findings highlight trace water as a significant factor for reliable catalyst screening and industrial ammonia cracking scale‐up ...

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal

Chemie Ingenieur Technik, EarlyView.
Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.
