Hydrogenation of Tetralin over Supported Ni and Ir Catalysts

CO Hydrogenation over Alumina-Supported Sulfide Cluster Catalysts

Bimetallic Mo-Fe and Mo-Co sulfide clusters were anchored on AI,O, and used for CO hydrogenation. In addition to methane, significant amounts of dimethyl ether were produced. The reaction orders obtained from power rate laws for methanation indicated that the surfaces of the catalytic ensembles were not completely saturated by CO, in contrast to the observations for most conventional CO hydroge...

Gas phase selective hydrogenation over oxide supported Ni-Au.

The chemoselective continuous gas phase (T = 573 K; P = 1 atm) hydrogenation of nitroarenes (p-chloronitrobenzene (p-CNB) and m-dinitrobenzene (m-DNB)) has been investigated over a series of oxide (Al2O3 and TiO2) supported Au and Ni-Au (1 : 10 mol ratio; 0.1-1 mol% Au) catalysts. Monometallic supported Au with mean particle size 3-9 nm promoted exclusive formation of p-chloroaniline (p-CAN) an...

Enhanced Oxygen Activation over Supported Bimetallic Au-Ni Catalysts

Vapour phase hydrogenation of nitrobenzene over metal ( Ru , Ni , Pt , Pd ) supported on Ca 5 ( PO 4 ) 3 ( OH ) catalysts

Vapour phase hydrogenation of nitrobenzene is carried out over metal (Pt, Pd, Ru, Ni) supported on hydroxyapatite (HAP) catalysts at atmospheric pressure and low temperatures ranging from 225–350 °C. The time-on-stream analysis reveals that 2 wt.%Pd/HAP is quite stable up to 6 h of continuous operation and is found to be an efficient catalyst. The other metal catalysts suffer deactivation, whic...

Effect of textural properties of Ni (Nano)-supported catalysts on the selective benzene hydrogenation in the vapor phase

Ni catalysts supported on Nano porous catalysts were prepared by the impregnation method and tested for vapor phase hydrogenation of benzene. The textural and physico-chemical properties of Ni catalysts were characterized by the X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope and N2 adsorption-desorption analysis. The catalytic evaluation reve...
