Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
Chemie Ingenieur Technik, EarlyView.This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines
Chemie Ingenieur Technik, EarlyView.Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.

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

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.
