This work focuses on simulations for design optimization by dividing a filter into two zones with different amounts of noble metal in a porous wall. For this, a two-dimensional stationary model with a simplified kinetics is devised and different appendages are followed up. Furthermore, time-dependent simulations with this 2D-model are presented.

Signal processing algorithms for chemical sensing/monitoring have been subject of considerable research interest in the recent years mainly due to their diverse applicability. When the concentration of chemical agent is small, the dispersion of particles is governed by stochastic differential equations describing more complex motion mechanisms such as Brownian motion. In this paper we propose the ...

A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to allow the study of gas phase reactions at low (atmospheric) and high pressures (up to 20 MPa), with the ...

Pitting corrosion is a complex phenomenon where rates of: i) chemical reactions, ii) diffusion of various species involve in those reactions, and iii) species dissolution at the metal-electrolyte interface are fully dependent on each other, except under special conditions or assumptions. One set of such conditions is that: a) there are no species concentration gradients due to the rapid mixing of ...

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the Finnish spent fuel repository). A characteristic of these models lies in the need to integrate prior information, ...

We have started constructing preliminary design COMSOL models of a bacteriologically driven \'fuel cell\' that is intended to process waste products, such as carbon dioxide and brine, from a crewed vehicle. At this early stage, this complex system is reduced to two electrodes separated by a membrane. The electrolyte is a brine appropriate for growing methanogenic bateria, though none are ...

In recent years lab-on-microchip technology has become a powerful tool for micro-scale analysis of biochemical processes. In the studied system the overall process consists of transport, convection, diffusion, reaction and adsorption processes. Two compounds A and B, contained in a carrier fluid (buffer), are introduced into a reaction channel via a Y-shaped double-inlet. As the streams flow ...

A planar anode-supported intermediate temperature solid oxide fuel cell operating on syngas fuel at 750°C was analyzed in this study. The effects of varying syngas fuel inlet compositions on species and temperature distributions, water gas shift reaction rate, potential for carbon formation and electrochemistry were considered. A 2-D COMSOL® model was developed which included separate defined ...

Introduction: Development of next-generation chemical processes that have zero emissions is a key environmental objective for sustainable development. The manufacture of H2SO4 by the air oxidation of SO2 to SO3 is an important technology where an opportunity exists for new catalyst development and process innovation by reducing emissions of unconverted SO2 in process reactor tail gases owing to ...
