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.

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 ...

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.
