Kinetics of benzene hydrogenation on supported platinum, palladium, rhodium and ruthenium catalysts.

Different Reaction Pathways for the Hydrogenation of o-cresol on Ruthenium, Rhodium, Palladium and Platinum Nanoparticles Supported on Carbon

Continuous flow hydrogenation using polysilane-supported palladium/alumina hybrid catalysts

Continuous flow systems for hydrogenation using polysilane-supported palladium/alumina (Pd/(PSi-Al(2)O(3))) hybrid catalysts were developed. Our original Pd/(PSi-Al(2)O(3)) catalysts were used successfully in these systems and the hydrogenation of unsaturated C-C bonds and a nitro group, deprotection of a carbobenzyloxy (Cbz) group, and a dehalogenation reaction proceeded smoothly. The catalyst...

Study of HMS Modified ZrO2 Supported Platinum Catalysts for Toluene Removal: Catalytic Combustion and Kinetics Study

Reaction behaviors and kinetics of catalytic oxidation of toluene with different feed flows over Pt/Zr(x)-HMS catalysts with Si/Zr ratio equal to 5, 10, 20 and 35 were investigated over a wide temperature range (200 – 500 oC). Results show that Pt/Zr(x)-HMS performs more easily toluene oxidation. The kinetic data were fitted by the Power-law and Mars–van Krevelen kinetic models. The fitting res...

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...

Ruthenium and Osmium as Hydrogenation Catalysts

Little attention has been given to the use of ruthenium and osmium as catalysts for vapour-phase reactions. This paper shows that both these metals when supported on alumina possess signijcant activity for the hydrogenation of unsaturated hydrocarbons. In the hydrogenation of butene, butadiene and acetylene their activity is comparable with that shown by the other platinum group metals, althoug...
