Methane oxidation over a honeycomb Pd-only three-way catalyst under static and periodic operation

Davide Ferri, Oliver Kröcher

Natural gas is receiving increasing awareness as fuel for passenger vehicles due to its very low specific CO2 emissions. However, control of CH4 emissions from natural gas combustion in stoichiometric engines requires a specific three-way catalyst (TWC). T ...

Advances in Vanadium-Based Catalyst Research for the Selective Catalytic Reduction of NOx by NH₃

Adrian Marberger

The most efficient after-treatment technology for reducing harmful NOx emissions from stationary and mobile sources of diesel exhaust is the selective catalytic reduction (SCR) of NOx with ammonia (NH3). Vanadium-based SCR catalysts reduce NOx selectively ...

Building Virtualization Engine: a Novel Approach Based on Discrete Event Simulation

Maher Kayal, Georgios Lilis, Olivier Valentin Henri Van Cutsem

This paper proposes and validates a Discrete Event Simulation (DES) engine for the Smart-Building (SB). It strives to virtualize the common elements found within it and integrates them transparently to an existing Building Management System (BMS), along wi ...

Impact of Operating Regime on Aviation Engine Emissions: Modeling Study

Pénélope Leyland

This work is focused on the numerical analysis of pollutant formation in an aviation gas turbine engine at different values of power setting. The analysis is conducted on the basis of a comprehensive approach treating the reactor net model for description ...

Amer Inst Aeronautics Astronautics2013

A review of the state of the art gas turbine power plants designs with CO2 capture was performed to set up a list of technologies to be considered in a conceptual process superstructure. It has been found that the efficiency and economics of carbon dioxide ...

CFD Simulations Of Pollution Control Systems: DPF and SCR

Peter Loveday

New EU and US emissions regulations require the development of advanced after- treatment systems for non-road diesel engine exhausts. To help develop these at Liebherr Machines Bulle, the use of CFD has been adopted. The pro ject used two main models: one ...
