The reaction of steam with ethanol, ethanol + phenol, ethanol + phenol + tetrahydrothiophene, methanol + phenol, methanol + naphthalene and methanol + phenol + naphthalene mixtures in the vapour phase has been studied over catalysts based on Ni/Al2O3. The main conclusion is that Ni-alumina based steam reforming catalysts are effective for steam...

Nickel catalysts supported on pure alumina (Puralox) and 5% silica-containing alumina (Siralox) have been prepared, characterized (XRD, UV-vis-NIR, IR, H2-TPR and FE-SEM) and tested. It is confirmed that small amounts of silica hinder the surface area loss of alumina upon calcination, allowing the retention of higher surface areas also when NiO...

Mixed ceria-zirconia oxide (CZ91, Ce:Zr = 9:1) has been used to support Nickel (CZ91Ni), Cobalt (CZ91Co) and bimetallic Nickel/Cobalt active phases (CZ91NiCo) to be tested in Ethanol Steam Reforming reaction (ESR). H2-TPR analyses and IR studies of adsorbed probe molecules suggest that ceria/zirconia actually favors the reduction of supported...

La2O3/gamma-Al2O3, NiO/gamma-Al2O3 and NiO/La2O3/gamma-Al2O3 samples have been prepared by conventional impregnation, using silica-free gamma-Al2O3 support. The materials have been characterized, as such or after reaction, with XRD, skeletal IR, UV-vis-NIR, XPS and FESEM techniques. The catalytic activity has been evaluated in ethanol...

Lanthana on alumina samples (0.2, 0.8 and 4.7 theoretical monolayers) were prepared by incipient wetness impregnation using γ-Al2O3 as support. Characterization has been performed by BET, XRD, skeletal FT-IR, DR-UVvis, XPS, HR-TEM, IR spectra of the surface OH, adsorbed pyridine and CO2, and isopropanol TPD. Ethanol conversion was investigated...
