Selective hydrogenation in trickle-bed reactor. Experimental and modelling including partial wetting. [PDF]
, 2003 A steady state model of a trickle bed reactor is developed for the consecutive hydrogenation of 1,5,9-cyclododecatriene on a Pd/Al2O3 catalyst. Various experiments have shown that the selectivity of this reaction towards the product of interest is much ...

Chiral pyridyl phosphinite catalysts and the development of structure selectivity relationships in the asymmetric hydrogenation of trisubstituted alkenes [PDF]
, 2010 The current trend in developing asymmetric catalysts is towards creating specialized molecules with tailored functions for increased selectivity in classes of substrates rather than general catalysts capable of broad application.

Model arenes hydrogenation with silica-supported rhodium nanoparticles:The role of the silica grains and of the solvent on catalytic activities [PDF]
, 2009 Silica-supported rhodium-based nanoheterogeneous catalysts were easily prepared by impregnation with a pre-stabilized colloidal suspension. The resulting catalysts contain rhodium nanoparticles well-dispersed in the silica pores with a mean size of 5 nm.
