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.

Pollinator risks and recovery from air pollutant interactions during the fossil‐fuel transition

Frontiers in Ecology and the Environment, EarlyView.
By altering the composition and concentration of floral scents, air pollutants such as ozone (O3) and nitrogen oxides (NOx) disrupt the ability of insect pollinators to locate flowers, threatening biodiversity and crop production. We examine the impact of these pollutants on pollinator performance and evaluate the short‐ and long‐term consequences of ...
