Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines

open access: yesChemie 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

open access: yesChemie 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
