Al2o3 Catalyst

The kinetics of the selective hydrogenation of acetylene in the presence of an excess of ethylene has been studied over a 0.05 wt. % Pd/α-Al2O3 catalyst. The experimental reaction conditions were chosen to operate under intrinsic kinetic conditions, free from heat and mass transfer limitations. The data could be described adequately by a Langmuir–Hinshelwood rate-equation based on a series of sequential hydrogen additions according to the Horiuti–Polanyi mechanism. The mechanism involves a single active site on which both the conversion of acetylene and ethylene take place.

Pd-TiO2 nanoparticles prepared by sol-immobilisation are very active for selective hydrogenation of furfural under mild conditions, and addition of Pt enhances performance to achieve a 95% yield of tetrahydrofurfuryl alcohol.
