Platinum Nanoparticle Shape Effects on Benzene Hydrogenation Selectivity
Nano Letters, 2007Benzene hydrogenation was investigated in the presence of a surface monolayer consisting of Pt nanoparticles of different shapes (cubic and cuboctahedral) and tetradecyltrimethylammonium bromide (TTAB). Infrared spectroscopy indicated that TTAB binds to the Pt surface through a weak C-H...Pt bond of the alkyl chain.

Pt/Al2O3 catalysts for benzene hydrogenation
1998A number of platinum based catalysts were prepared on gamma alumina supports with a view to investigate the effect of the presence of chloride and other preparation variables on the performance. The catalyst samples were evaluated for vapour phase benzene hydrogenation activity and dispersity at room temperature towards hydrogen and carbon monoxide ...

Modelling of catalyst pellet poisoning for benzene hydrogenation
Journal of Chemical Technology & Biotechnology, 1993AbstractBased on the kinetics of benzene hydrogenation, pore diffusion and catalyst deactivation, time‐dependent effectiveness behaviour of a single NiSiO2Al2O3 catalyst pellet where the chemical reaction rate is determined by pore diffusion was simulated for different conditions of operation.Poisoning kinetics were measured in a series of ...

Fluid Phase Equilibria, 2001
Abstract Bubble points of the HCl–water–isopropanol and the HCl–water–isopropanol–benzene systems and liquid–liquid equilibria (LLE) of the HCl–water–benzene and the HCl–water– isopropanol–benzene systems were measured at 25–85°C and 30–70°C, respectively. The electrolyte nonrandom two-liquid model proposed by Chen et al. [C.-C. Chen, H.I. Britt, J.F.

Benzene hydrogenation: an isotopic transient study
The Journal of Physical Chemistry, 1986This paper reflects how the kinetic method of isotopic transients widely used in CO hydrogenation up to now can be extended to the case of benzene hydrogenation. The stationary amounts of reactive adspecies are thus determined during reaction on nickel catalysts. In apparent contrast to the observed orders vs.

Vapor‐liquid equilibria in hydrogen‐benzene and hydrogen‐cyclohexane mixtures
AIChE Journal, 1965AbstractA new vapor‐liquid equilibrium experimental facility has been built for and operated on light gas‐hydrocarbon systems. The range of operating conditions are 3 to 1,000 atm. and 25° to 400°C. A dynamic flow type of equilibrium cell is used. This and most of the other apparatus are from designs by Michels.

Journal of Catalysis, 1976
Abstract Studies of benzene adsorption on a nickel-silica catalyst have suggested the existence of three forms of chemisorption, in addition to physical adsorption. The chemisorbed forms cover only a part of the surface and are, respectively: (a) a reactive form, active in normal benzene hydrogenation, and discernible up to 110 °C, (b) a form of low ...
