Monodispersed Pd-nanoparticles on carbon fiber fabrics as structured catalyst for selective hydrogenation

Semagina, N.Renken, A.Kiwi-Minsker, L.2007-10-242007-10-242007-10-24200710.1016/j.ces.2006.11.023https://infoscience.epfl.ch/handle/20.500.14299/13288WOS:00024957270008411228Monodispersed Pd-nanoparticles (similar to 8nm) prepared via a modified microemulsion method were deposited on active carbon fibers (ACF) fabrics and studied in a semi-batch 1-hexyne liquid-phase hydrogenation. The catalyst Pd(0.45 wt%)/ACF demonstrated > 96% selectivity to 1-hexene up to 90% of conversion. Initial activity at 303 K, 1.3 MPa pressure, in D-heptane as a solvent was 0.14 kmo1H(2) kg(Pd)(-1) S-1. Assuming a Langmuir-Hinshelwood kinetics with a weak hydrogen adsorption a kinetic model was developed. It was shown to be consistent with the experimental data and allowed determining the main kinetic parameters. (c) 2006 Elsevier Ltd.
