Kinetic Modeling of the Hydrogenation of 1,5,9-Cyclododecatriene on Pd/Al₂O₃ Catalyst Including Isomerization

Abstract

The kinetic modeling of the hydrogenation of 1,5,9-cyclododecatriene has been studied using a Pd/Al2O3 catalyst in a slurry reactor on the basis of a complete isomers analysis. A reaction scheme involving multistep hydrogenation and reversible isomerization reactions has been considered and a kinetic model of Langmuir−Hinshelwood type proposed. The kinetic parameters were estimated from experimental batch slurry reactor data. The model predictions of cyclododecene selectivity at different pressures agree well with the experimental data.
