Single CSTR can be as effective as an SBR in selecting PHA-storing biomass from municipal wastewater-derived feedstock
A key step in the production of polyhydroxyalkanoates (PHAs) from organic waste streams is the selection of a biomass with a high PHA-storage capacity (selection-step), which is usually performed in sequencing batch reactor (SBR) according to the state-of- ...
2023Flowing Gas Experiments Reveal Mechanistic Details of Interfacial Reactions on a Molecular Level at Knudsen Flow Conditions
Christian Ludwig, Michel Rossi, Riccardo Iannarelli
Knudsen flow experiments and its interpretation in terms of adsorption/desorption kinetics as well as quantitative uptake on substrates of interest is presented together with the description of critical design parameters of the Knudsen Flow Reactor (KFR). ...
2022Enhanced Solar-to-Fuel Efficiency of Ceria-Based Thermochemical Cycles via Integrated Electrochemical Oxygen Pumping
Sophia Haussener, Clemens Gregor Suter, Meng Lin
The solar thermochemical cycle based on ceria is a promising route for renewable fuel production. The solar-to-fuel efficiency of a thermochemical reactor is highly dependent on the oxygen removal during the reduction step. Conventional nitrogen sweeping ( ...
AMER CHEMICAL SOC2022Construction of Fe3O4 bridged Pt/g-C3N4 heterostructure with enhanced solar to fuel conversion
Michael Graetzel, Shaik Mohammed Zakeeruddin
In this study, we report the effects of co-catalysts of Pt nanoparticles and Fe3O4 clusters on photocatalytic behaviors of g-C3N4 (CN) and the use of the resulting photocatalyst for CO2 photoreduction to solar fuels in a flow reactor operated at room-tempe ...
ELSEVIER2022Crossover of liquid products from electrochemical CO2 reduction through gas diffusion electrode and anion exchange membrane
Andreas Züttel, Wen Luo, Jie Zhang
We reveal that a significant amount (>30%) of the liquid products from electrochemical CO2 reduction (CO2RR) in a flow reactor can cross the gas diffusion electrode (GDE) and anion exchange membrane (AEM). Crossover of volatile products through the GDE occ ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2020Electrochemical reconstruction of ZnO for selective reduction of CO2 to CO
Andreas Züttel, Emanuele Moioli, Wen Luo, Jie Zhang, Kun Zhao, Qin Zhang
Electrocatalytic conversion of CO2 to valuable chemicals is a highly promising route to close the carbon cycle. Herein, Zn catalysts derived from electrochemical reconstruction of ZnO materials are presented as efficient CO2-to-CO catalysts. We found that ...
2020On isothermality in some commonly used plug flow reactors for X-ray based investigations of catalysts
Dragos-Constantin Stoian, Mark Adrian Newton
We compare two reactor setups commonly used to make operando measurements of catalyst behavior using X-rays in terms of the degree to which they may be considered to yield radial and axial isothermality. We use axial and radial Cu K-edge XANES mapping of c ...
ROYAL SOC CHEMISTRY2019Dynamic Optimization of Reaction Systems via Exact Parsimonious Input Parameterization
Dominique Bonvin, Diogo Filipe Mateus Rodrigues
This paper discusses the use of parsimonious input parameterization for the dynamic optimization of reaction systems. This parameterization is able to represent the optimal inputs with only a few parameters. In the context of batch, semibatch, and continuo ...
AMER CHEMICAL SOC2019Sequential Cascade Electrocatalytic Conversion of Carbon Dioxide to C-C Coupled Products
Cascade catalytic processes perform multi-step chemical transformations without isolating the intermediates. Here, we demonstrate a sequential cascade pathway to convert CO2 to C2+ hydrocarbons and oxygenates in a two-step electrocatalytic process using CO ...
2019Modifier adaptation with guaranteed feasibility in the presence of gradient uncertainty
Dominique Bonvin, Timm Faulwasser, Alejandro Gabriel Marchetti, Martand Singhal
In the context of real-time optimization, modifier-adaptation schemes use estimates of the plant gradients to achieve plant optimality despite plant-model mismatch. Plant feasibility is guaranteed upon convergence, but not at the successive operating point ...
