Mn-Zr mixed oxide materials have been prepared by a sol-gel method from a Mn (III) precursor salt and a solution of zirconium acetate in acetic acid, being characterized from a structural and morphological point of view. Conventional solid state techniques show that as obtained powders are formed by mixtures of manganese and zirconium acetates...

The steam reforming of ethanol/phenol mixture (168 gTOT/N m3, ethanol: phenol 2:1 mol), assumed asa model for tar mixtures, has been studied over Ni/Al2O3, Ni-Mg/Al2O3and Ni-B/Al2O3catalysts. Theeffects of reaction temperature and of the presence of sulphur have been investigated. Catalysts havebeen characterized by XRD, IR of adsorbed CO, TPR,...
