Kinetics of the solvent-free hydrogenation of 2-methyl-3-butyn-2-ol over a structured Pd-based catalyst

Albert Renken, Lioubov Kiwi, Rocio Micaela Crespo Quesada, Martin Grasemann

The solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) was studied over a Pd/ZnO structured catalyst and compared to its behavior in water-assisted conditions. The catalytic behavior was correlated with the s ...

Compact reactor for continuous multi-phase reactions

Martin Grasemann

The objective of this thesis is the development of a compact reactor for continuous three-phase reactions in single-pass configurations. The design is based on a bubble column reactor staged with layers of catalytic material. To make the reactor suitable f ...

N2O Decomposition over Fe-ZSM-5 Studied by Transient Techniques

Albert Renken, Lioubov Kiwi, Bryan Bromley, Petra Prechtl

N2O decomposition to gaseous N-2 and O-2 catalyzed by a commercial Fe-ZSM-5 has been studied by different transient techniques: (i) via the transient response methods at ambient pressure, (ii) via the temporal analysis of products (TAP) reactor under vacuu ...

Strain-relief pattern as guide for the formation of surface-supported bimolecular nanoribbons

Martin Peter Bieri, Marta Canas Ventura

We demonstrate the suitability of the Ag/Pt(111) strain-relief pattern as efficient template for controlling the formation of well defined heteromolecular nanostructures. Two different species of molecular building blocks with complementary end-group funct ...

Fast temperature cycling of the catalytic CO oxidation using microstructure reactors

Martin Luther

The possibility to increase the performance (productivity or selectivity) of a chemical reactor by using periodic variations of reaction parameters (e.g. reactant concentration or temperature) has been theoretically envisaged since the beginning of the 70t ...

Pd Nanoparticles in a Supported Ionic Liquid Phase: Highly Stable Catalysts for Selective Acetylene Hydrogenation under Continuous-Flow Conditions

Paul Joseph Dyson, Lioubov Kiwi, Gabor Laurenczy, Marina Ruta

Monodispersed Pd nanoparticles of 5 and 10 nm were obtained via reduction of Pd(acac)2 dissolved in ionic liquid (IL), [bmim][PF6], or [bmimOH][TF2N], supported on carbon nanofibers (CNF) anchored to sintered metal fibers (SMF). Using [bmimOH][TF2N], the m ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Decomposition analysis of reactivity effect predictions for modern LWR fuel

Filippo Tani

The increasing complexity and heterogeneity of modern light water reactor (LWR) fuel assemblies impose new challenges to current reactor physics codes in terms of maintaining and improving the quality of neutronics predictions for the core. In particular, ...

TiO2-photocatalyzed As(III) oxidation in a fixed-bed, flow-through reactor

Janet Gordon Hering

Compliance with the U.S. drinking water standard for arsenic (As) of 10 μg L-1 is required in January 2006. This will necessitate implementation of treatment technologies for As removal by thousands of water suppliers. Although a variety of such technologi ...

Integrated nanoreactor system

Pierre-Yves Bolinger

This thesis describes a method that allows the production in parallel of nano-reactor systems whose function is controlled by a remote stimulus. The reactors comprise a nested system of lipid vesicles part of which release their content during a thermotrop ...
