Synthesis and Mathematical Modelling of the Preparation Process of Nickel-Alumina Catalysts with Egg-Shell Structures for Syngas Production via Reforming of Clean Model Biogas

For the work presented herein nickel catalysts supported on γ-alumina extrudates (Ni/Al) with an egg-shell structure were prepared, using a modified Equilibrium Deposition Filtration (EDF) technique. Their performance was compared, for biogas dry reforming reaction, corresponding Ni/Al uniform structure, synthesized via conventional wet impregnation method. The bulk and surface physicochemical characteristics of all final determined ICP-AES, N2 adsorption-desorption isotherms, XRD, SEM, TEM. A theoretical model describing process EDF extrudates, based Lee Aris model, also developed. It concluded that following specific conditions, macro-distributions can be successfully predicted, in agreement experimental results. shown had higher H2 yield comparison ones structure. difference catalytic attributed to improved structural properties catalysts, resulting from technique used their preparation.
