Selective hydrogenation of amides with supported transition metal nanoparticles

Recruting institution: DTU
Diploma-delivering institutions: DTU, UPS
Thesis co-directors: Anders Riisager (DTU, Lingby, DK), Karine Philippot (LCC, Toulouse, FR)
Secondment host: IFP Energies Nouvelles (FR)

Objectives

Develop new catalysts (mono- and bimetallic) based on supported metal nanoparticles [1] for the hydrogenation of amides reactions [2]. Higher efficiency is expected owing to the high surface/volume ratio provided by the ultra-small nanoparticles produced by the organometallic approach. Apply the best catalytic systems to continuous flow conditions using the SILP thechnology [3]; optionally in combination with scCO2 as substrate carrier for low-volatile substrates

Expected Results

Obtain nanocatalysts that react under much milder conditions (T≤100°C and P(H2) ≤20 bar) than those reported today, which work under harsh conditions (T~150-300°C ; P(H2)~100-350 bar) and evaluate their recyclability for at least 5 successive runs. Combine the advantage of the catalytic performance of nanocatalysts with those of the SILP technology to perform continuous liquid phase flow catalysis in a fixed bed reactor.
