Methane Dry Reforming is a promosing process to obtain hydrogen in a sustainable way. However, despite the latest advances, it is not yet applied at industrial level due to easy deactivation of the catalytic systems, in particular the ones based on Ni. This because of two reasons: coke deposition, formed by secondary reactions, and sintering of active phase, due to the high temperatures required. The aim of this work is to study a Ni@Al2O3 core-shell catalyst applied to Dry Refomring process. Its characteristics were investigated and compared with other catalytic systems, synthetized with different methodologies (for example by coprecipitation). The catalysts obtained were tested for the DRM reaction at 650°C in a fixed bed reactor and the fresh and spent samples were characterized, using various techniques, including: XRD, SEM, TEM, TPR, TPO, nitrogen physisorption.
