Among different types of Fe-exchanged zeolites, Fe-BEA exhibits very promising surface properties for developing efficient urea or NH3-SCR systems. In this work, dedicated experimental and kinetic modeling studies were performed in order to elucidate mechanistic aspects related NH3 storage release on these catalysts. A series adsorption desorption experiments over both H- BEA taking into account a broad range operating conditions. Coupling FTIR spectroscopy, adspecies characterized. gaseous...
The storage of NH3 over Fe-ZSM5 catalysts was investigated through a multisite approach where the reaction rate expressions are based on mean-field approximation. A kinetic model, including five different surface sites formulated from literature data and validated broad range adsorption desorption experiments, showing interest selected approach. For simulation purposes, values capacity used in our test cases were evaluated structural properties zeolites with respect to Si/Al Fe/Al ratios....
The Selective Catalytic Reduction of nitrogen oxides (NOx) by NH3 is a well established after-treatment technology. storage key step the overall SCR process, affecting catalyst's deNOx efficiency. In present study, over Fe- and Cu-zeolite based, Urea-SCR catalysts for mobile diesel engines was investigated means modeling simulation. A single-site multi-site kinetic model, reported in literature, were adopted integrated into simulation environment LMS.Imagine.Lab AMESim. models compared...
<div class="section abstract"><div class="htmlview paragraph">State of the art battery electric vehicles (BEVs) become increasingly attractive, thanks to their top performance and high energy efficiency. Nevertheless, despite improvements in motors efficiency motive batteries technology, there is still space for improving BEVs’ autonomy. Among others, use a multi-speed, instead single-speed transmission system has potential optimize BEV’s consumption driving range. In this...
Innovative high porosity SCR substrates are targeting at optimum utilization of catalyst amounts without increasing pressure drop. Mathematical modeling such technologies is challenging, requiring accurate description both chemistry and mass transfer inside the active material. In this work, a systematic experimental study conducted towards calibrating comprehensive commercial simulation model for Cu-zeolite catalyst. Based on calibrated model, it possible to evaluate different substrate...
