Abstract

Eleven C₂ to C₈ alkenes were hydrogenated on a reduced sulphided industrial nickel-tungsten catalyst. Kinetics of the reaction was investigated in detail for ethylene and data were correlated by different equations. Best fit was obtained by three equations of the Langmuir-Hinshelwood type and these were used to describe hydrogenation of the other alkenes. Logarithms of the rate constants obtained were correlated linearly with the sum of steric constants E₀^s of substituents of semihydrogenated state R¹R²R³C-*. Also adsorption coefficients of alkenes were structure dependent, increased with molecular weight of alkene and correlated roughly with boiling points.
