Effect of Extraframework Aluminum of USY Zeolite on Sulfur Tolerance of Pd-Pt/USY Catalyst
Extraframework aluminum Delaminated USY zeolite Palladium platinum catalyst
2009/8/4
A series of bimetallic Pd-Pt (mole ratio Pd:Pt=4:1) catalysts supported on ultrastable Y (USY) zeolites and delaminated USY zeolites were prepared and characterized by XRD, 27Al MAS NMR and CO adsorp...
Sulfur Tolerance of Pd, Pt and Pd-Pt Catalysts Supported on Amorphous Silica
Noble metal catalyst Silica support Pore diameter Sulfur tolerance Aromatics hydrogenation
2009/7/24
Effect of pore structure of silica support on sulfur tolerance and tetralin hydrogenation activity of Pd, Pt and Pd-Pt catalysts was investigated. Pore diameter of SiO2 supports affected the sulfur t...
Sulfur-tolerance of Al2O3- and TiO2-supported Bimetallic Pt-Pd Catalysts for Naphthalene Hydrogenation
Naphthalene hydrogenation Bimetallic catalyst Platinum-palladium catalyst
2009/7/23
Naphthalene hydrogenation was carried out over TiO2- and Al2O3-supported bimetallic Pt-Pd catalysts at 0.95-2.45 MPa and 473 K with and without addition of dimethyldisulfide. The bimetallic catalysts...
