On the Usability of Pt/Al2O3 Catalysts for Exhaust Gas After Treatment in Ammonia Combustion Engines

Chemie Ingenieur Technik, EarlyView.
Ammonia engines emit no CO2 but exhibit elevated emissions of NH3 and NOx, where conventional SCR systems are not effective due to the significant excess of NH3. This study investigates Pt‐based oxidation catalysts in a bypass configuration to adjust the NH3/NOx ratio, analyzing catalyst parameters and their impact on N2O formation to identify optimal ...

Nonlinear Active Site Dynamic Behavior Over In Situ Generated Working Zeolites

Chemie Ingenieur Technik, EarlyView.
The methoxymethyl mechanism over α, β, and γ site ensembles and the dynamic site‐interconversion mechanism reduce the induction period of propylene formation. The methoxymethyl mechanism acts on site ensemble α generating surface methoxy species (SMS), which, through the dynamic site‐interconversion mechanism, lead to SMS on site ensembles β and γ that

Incorporating ethylene glycol into hydrophilic poly(ether‐b‐amide) membranes for enhanced gas dehumidification performance

The Canadian Journal of Chemical Engineering, EarlyView.
Using ethylene glycol to enhance water vapour permeation for gas dehumidification. Abstract In the present study, ethylene glycol (EG) was incorporated into hydrophilic poly(ether‐b‐amide) matrix membranes to enhance the membrane performance for gas dehumidification (e.g., H2O/N2, H2O/CH4, and H2O/CO2 separations). Exploiting EG as a hygroscopic agent,

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.
