Upgrading of Simulated Syngas by Using a Nanoporous Silica Membrane Reactor
Authors: Wei L. , Kawamoto K. 
Published: March 2013

AbstractThe permeance properties of a nanoporous silica membrane were first evaluated in a laboratory‐scale porous silica membrane reactor (MR). The results indicated that CO, CO2, and N2 inhibited H2 permeation. Increased H2 permeability and selectivity were obtained when gas was transferred from the lumen side to the shell side. This was therefore selected as a suitable permeation direction. On this basis, upgrading of simulated syngas was experimentally investigated as a function of temperature (150 – 300 °C), feed pressure (up to 0.4 MPa), and gas hourly space velocity (GHSV), by using a nanoporous silica MR in the presence of a Cu/ZnO/Al2O3 catalyst. The CO conversion obtained with the MR was significantly higher than that with a packed‐bed reactor (PBR) and broke the thermodynamic equilibrium of a PBR at 275 – 300 °C and a GHSV of 2665 h–1. The use of a low GHSV and high feed pressure improved the CO conversion and led to the recovery of more H2.
Load–Collapse–Release Cascades of Amphiphilic Guest Molecules in Charged Dendronized Polymers through Spatial Separation of Noncovalent Forces
Authors: Kurzbach Dennis , Zhang Xiuqiang , Zhang Baozhong , Arnold Philipp , Hinderberger Dariush 
Published: March 2013

AbstractThe ability to pack guest molecules into charged dendronized polymers (denpols) and the possibility to release these guest molecules from subsequently densely aggregated denpols in a load–collapse–release cascade is described. Charged denpols, which constitute molecular objects with a persistent, well‐defined envelope and interior, are capable of incorporating large amounts of amphiphilic guest molecules. Simultaneously, multivalent ions can coordinate to the surfaces of charged denpols, leading to counterion‐induced aggregation of the already guest‐loaded host structures. Thus, although the local guest concentration in denpol‐based molecular transport might already be initially high due to the dense guest packing inside the dendritic denpol scaffolding, the “local” guest concentration can nonetheless be further increased by packing (through aggregation) of the host–guest complexes themselves. Subsequent release of guest compounds from densely aggregated dendronized polymers is then possible (e.g., through increasing the solution concentration of imidazolium‐based ions). Augmented with this release possibility, the concept of twofold packing of guests, firstly through hosting itself and secondly through aggregation of the hosts, gives rise to a load–collapse–release cascade that strikingly displays the high potential of dendronized macromolecules for future molecular transport applications.
CeO2‐Based Pd(Pt) Nanoparticles Grafted onto Fe3O4/Graphene: A General Self‐Assembly Approach To Fabricate Highly Efficient Catalysts with Magnetic Recyclable Capability
Authors: Wang Xiao , Liu Dapeng , Song Shuyan , Zhang Hongjie 
Published: March 2013

AbstractNew Pd(Pt) catalysts have been fabricated by assembling multicomponents of Fe3O4 and CeO2/Pd(Pt) on the surface of reduced graphene oxide (RGO) nanosheets in layers. The as‐obtained Pd(Pt) catalysts exhibit extremely high catalytic activity in the selective hydrogenation reaction of nitrobenzene. Owing to the presence of Fe3O4, the catalysts can be easily recycled from the catalytic system through magnetic separation. Their high activity, stability, and magnetic recyclability make the as‐obtained hybrids very promising as catalysts in catalytic applications. Compared to other traditional multishell magnetic catalysts that were prepared by means of layer‐by‐layer technology, our process is much more facile and more easily controlled.

Holdup and Pressure Drop in Micro Packed‐Bed Reactors for Fischer‐Tropsch Synthesis
Authors: Knobloch Carsten , Güttel Robert , Turek Thomas 
Published: March 2013

AbstractLow‐temperature Fischer‐Tropsch synthesis was investigated in micro packed‐bed reactors. Co/Re/γ‐Al2O3 catalysts with different particle shapes and sizes (60 to 580 μm) were employed. Tubular reactor geometry with lengths of up to 1 m was chosen. Pressure drop measurements in the absence of reaction and during reaction were carried out. For analysis of the experimental data a reactor model was developed, which was also used for the determination of liquid holdup. It could be observed that the liquid holdup is independent of conversion, reaction temperature, C5+ productivity, and reaction rate. For irregularly shaped catalyst particles, a liquid holdup in the range of 3 % was observed.

AbstractDie photokataytische Wasserspaltung mit Sonnenlicht gilt als eine der Traumreaktionen zur nachhaltigen Erzeugung von Wasserstoff. In Kombination mit einer Brennstoffzelle könnte auf diese Weise eine grüne Energieversorgung sichergestellt werden. Um geeignete Kandidaten für die Wasserspaltung zu identifizieren, müssen die Halbreaktion im Einzelnen unter definierten Bedingungen untersucht werden. Dabei sollten Versuchsbedingungen gewählt werden, die auch in der Realität wiedergefunden werden können. In diesem Beitrag wird ein Versuchsaufbau für die Quantifizierung der Photokatalyse vorgestellt und an mesoporösem Kohlenstoffnitrid als Photokatalysator erprobt. Die Wasserstoffentwicklungsrate wird mit einem Referenzsystem aus Photovoltaik und Elektrolyse verglichen und für den Entwurf eines Prototypen genutzt.

AbstractDer steigende Energiebedarf und der damit verbundene CO2‐Ausstoß bei gleichzeitig abnehmenden Reserven an fossilen Rohstoffen erfordert neue Konzepte zur nachhaltigen Energieerzeugung. Das sogenannte Adam‐und‐Eva‐Prinzip zur CO2‐freien Gewinnung von Methanol aus Kohle und durch Nuklearenergie wird aufgegriffen und an heutige Gegebenheiten adaptiert. Als H2‐Quelle dient die Wasserelektrolyse mit Strom aus erneuerbaren Energien. Gleichzeitig wird mit dem bei der Elektrolyse gebildeten Sauerstoff in einem Oxyfuel‐Prozess Kohle verbrannt, dadurch Strom erzeugt und relativ reines CO2 erhalten. Dieses wird mit dem Elektrolyse‐Wasserstoff zu Methanol umgesetzt, das dann als Chemie‐ und Energierohstoff eingesetzt werden kann.
