Here, we report on the synthesis and catalytic properties of noble metal (Pd) nanoparticles in poly(ethyleneoxide)-block-poly(2-vinylpyridine) which forms stable micelles in aqueous solutions. The system has been studied as a homogeneous catalyst and heterogeneous one deposited on Al 2 O 3 in selective hydrogenation of acetylene alcohols. This process is of particular interest because hydrogenation products are intermediates in synthesis of vitamins (A, E, K) and fragrant substances (linalool). Synthesis of linalool (3,7-dimethyloctadiene-1,6-ol-3, LN) can be carried out by selective hydrogenation of dehydrolinalool (3,7-dimethyloctaen-6yne-1-ol-3, DHL)The catalytic systems revealed much higher activity (comparing to Lindlar catalyst) and up to 99.8 % selectivity. Hydrogenation kinetics has been studied. 240* Hydrodechlorination of Tetrachloroethene over a Pd/AlThe influence of different process parameters (such as temperature, pressure, hydrogen flow or solvent) in the deactivation of a Pd/Al 2 O 3 catalyst used in the hydrodechlorination of tetrachloroethene (TTCE) has been studied in this work. The stability of the catalyst has been observed to increase as temperature decreases and hydrogen flow increases. Only a slight positive effect of the operation pressure was observed whereas the influence of the solvent is correlated rather with its boiling point than with its chemical nature.Different regeneration procedures have been tested to recover the initial activity of the catalyst. Although no one of them achieve the total recovering of the initial activity, the leaching with ammonia lead to more stable catalysts. Considering the literature findings, this could be related with modifications in the surface acidity.The catalytic N 2 O decomposition on Rh-ZrO 2 without/with H 2 O was experimentally with a fixed bed reactor and theoretically studied. The model which is presented here allows us to determine the exit partial pressure of N 2 O in dependence on the entry partial pressure of N 2 O, O 2 and H 2 O, the reactor temperature and the residence time. A model of quasi-homogeneous fixed bed is used. However the effectiveness factor of the catalyst pellets is determined and introduced into the mass balance equations. Four different possible mechanisms of N 2 O decomposition were considered. Comparison with experimental data allowed us to select the following two expressions of the decomposition rate : and. This model helped us to determine the reaction mechanism and several physicochemical parameters.
