The Canadian Journal of Chemical Engineering, EarlyView.Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system
The Canadian Journal of Chemical Engineering, EarlyView.Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.
