High-performance supported catalysts with an ionic liquid layer for the selective hydrogenation of acetylene.
Pd-Ag shell catalysts impregnated with two different ionic liquids show considerable improvements both in ethylene selectivity and reduced ethane formation in the selective hydrogenation of acetylene under tail-end conditions.
متن کاملHydricity of an Fe-H Species and Catalytic CO2 Hydrogenation.
Despite renewed interest in carbon dioxide (CO2) reduction chemistry, examples of homogeneous iron catalysts that hydrogenate CO2 are limited compared to their noble-metal counterparts. Knowledge of the thermodynamic properties of iron hydride complexes, including M-H hydricities (ΔGH(-)), could aid in the development of new iron-based catalysts. Here we present the experimentally determined hy...
متن کاملSelective Hydrogenation of Acetylene over Palladium in Ultra High Vacuum
Under ultra-high-vacuum conditions, precoverage of a palladium(ll1) surface with hydrogen does not affect either the kinetics or the extent of acetylene uptake at 175 K. The subsequent reactive behavior of the system is however radically altered. Benzene formation is strongly suppressed, the transformation of adsorbed acetylene to another species (@-phase) is enhanced, and the yield of ethylene...
متن کاملPalladium Gallium Intermetallic Compounds for the Selective Hydrogenation of Acetylene Part II: Surface Characterization and Catalytic Performance
The structurally well-defined intermetallic compounds PdGa and Pd3Ga7 constitute suitable catalysts for the selective hydrogenation of acetylene. The surface properties of PdGa and Pd3Ga7 were characterized by X-ray photoelectron spectroscopy, ion scattering spectroscopy and CO chemisorption. Catalytic activity, selectivity and long-term stability of PdGa and Pd3Ga7 were investigated under diff...
متن کاملPredicting Kinetic Parameters of Acetylene Hydrogenation Reaction Via Optimization Techniques
In this study simulation and optimization of an industrial acetylene hydrogenation reactor was studied. Three well known kinetic models were used for a nearly similar catalyst to predict the industrial data. Due to the complexity of the reactions, none of the offered kinetic models could be considered as an exact kinetic model and it is necessary to determine the kinetic parameters. One of the ...
