Phenylacetylene semihydrogenation over a palladium pyrazolate hydrogen-bonded network
2021, Inorganica Chimica ActaActivity and selectivity of carbon supported palladium catalysts prepared from bis(Η<sup>3</sup>-allyl)palladium complexes in phenylacetylene hydrogenation
2018, Catalysis CommunicationsCitation Excerpt :It was the case in our previous work too [5]. In some other works, a constant catalyst activity establishes not at once, as in our case, but during next hydrogenation runs [34]. Carbon-supported palladium catalysts containing 9.1 wt% of Pd synthesized by reduction of bis(η3-allyl)palladium complexes as precursors with hydrogen demonstrated good figures in selective liquid-phase hydrogenation of PA to ST. Their performance obeys direct specific surface area effect: the more Pd specific surface area the greater their activity and selectivity.

2016, Chemical Engineering JournalRevisiting the reaction kinetics of selective hydrogenation of phenylacetylene over an egg-shell catalyst in excess styrene
2015, Chemical Engineering ScienceCitation Excerpt :In a previous study on the kinetics of selective hydrogenation of pygas over a commercial egg-shell catalyst (Zhou et al., 2010b), it was found that the effect of internal diffusion limitations was noticeable although the thickness of the active layer was only 60 μm. To date, a few studies have been devoted to the kinetics of selective hydrogenation of phenylacetylene (Chaudhari et al., 1986; Jackson and Shaw, 1996; Wilhite et al., 2002; Berenblyum et al., 2015), and the activation energies reported in the literature vary greatly, being 9.7–54.6 kJ/mol for the hydrogenation of phenylacetylene to styrene and 23.2–53.6 kJ/mol for the hydrogenation of styrene to ethylbenzene. Despite the fact that different types of catalysts may have different activation energies, the contribution of the effect of mass transfer processes should not be overlooked, especially for the selective hydrogenation reactions that have high reaction rates (Vergunst et al., 2001).
Surface dynamics of the intermetallic catalyst Pd<inf>2</inf>Ga, Part II - Reactivity and stability in liquid-phase hydrogenation of phenylacetylene
2014, Journal of CatalysisCitation Excerpt :It is 0.58 for pure Pd powder, meaning that double bond hydrogenation occurs clearly faster than triple bond hydrogenation. This is typically for Pd catalysts, e.g., in the gas-phase hydrogenation of acetylene [37] and was also reported for the liquid-phase hydrogenation of phenylacetylene [38]. The ability to form hydrides makes Pd highly reactive toward alkene hydrogenation [39].
