Resumen:
This work
presents a controllability analysis of a low temperature ethanol
reformer based on a cobalt catalyst for fuel cell application. The study is based on a nonlinear
dynamic model of a reformer which operates in three separate stages: ethanol
dehydrogenation to acetaldehyde and hydrogen, acetaldehyde steam reforming, and
water gas shift reaction. The controllability analysis is focused on the rapid
dynamics due to mass balances and is based on a linearization of the complex
non-linear model of the reformer. RGA, CN and MRI analysis tools are applied to
the linear model suggesting that a good performance can be obtained with
decentralized control for frequencies up to 0.1 rad/s.
