Abstract

A multi-scale approach for the analysis of reactant systems is a very important mean for the improvement of the understanding of the phenomena occurring at different scales of space and time, and for the support it brings to the experimental and design activities in particular for scale-up purposes. In previous works, the authors developed kinetics, cell and stack models for molten carbonate fuel cells, integrating all these scales of simulation in a code called SIMFC, which has been successfully validated on experimental data. The aim of the present work is to show the benefits that the coupling of plant simulation and small scale models can bring to the study of innovative applications and the design of particular configurations. In the frame of this paper, the authors analysed the integration of the calcium-looping technology coupled with molten carbonate fuel cells for the capture and sequestration of carbon dioxide using a series of different sources of fuel gas to evaluate the best options. In particular, this work analyses the exploitation of poor fuels in fuel cell that would not be possible without enrichment. The availability of a small scale model allowed to identify critical operating conditions (of both local temperature and composition) that decrease the performance and that cannot be easily identified with the use of only large scale model commonly employed for plant design and simulations.
