A novel compact reactor for three-phase hydrogenations

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid, Martin Grasemann

A novel reactor based on a bubble column staged by structured catalytic layers with integrated cross flow micro-heat-exchangers (HEX) was designed and tested in the solvent free hydrogenation of 2-methyl-3-butyn-2-ol (MBY) aiming on process intensification ...

CFD modelling of liquid–liquid multiphase microstructured reactor: Slug flow generation

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

Microreactor technology, an important method of process intensification, offers numerous potential benefits for the process industries. Fluid–fluid reactions with mass transfer limitations have already been advantageously carried out in small-scale geometr ...

Microstructured Catalytic Reactors

Albert Renken, Lioubov Kiwi

This chapter is a summary of recent advances in microreactors, which have become increasingly important in process development and chemical research. Microstructured chemical reactors are characterized by dimensions in the submillimeter range and, thus. su ...

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 ...

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 ...

Micro-Structured Reactors and Catalysts for the Intensification of Chemical Processes

Albert Renken

Process intensification is the term which describes an innovative design approach in chemical engineering aiming on a significant increase of the specific performance of chemical reactors and plants miniaturization, of at least an order of magnitude. In ad ...
