Hydrogenation of Benzene to Cyclohexene on an Unsupported Ruthenium Catalyst: Effects of Poisons

Odenbrand, Ingemar LU and Lundin, Sten Tore (1981) In Journal of Chemical Technology and Biotechnology 31(1). p.660-669
Abstract
The influence of poisoning of ruthenium catalysing the selective hydrogenation of benzene to cyclohexene has been studied. Both the yield of cyclohexene and the rate of hydrogenation are greatly affected by the degree of poisoning (e.g. FeSO4, FeCl3, TiCl3 and oxygen), and may also be optimised. A reproducible catalyst has been prepared by precipitating the catalyst precursor, as the hydroxide, in a glass vessel at 353 K without influence of corrosion products from the reactor material. The influence of the hydrogen pressure on activity has also been investigated. An optimum pressure for maximum yield of cyclohexene was obtained and a rate expression was formulated which could account for reaction orders varying with hydrogen pressure.
