Most biomass pretreatment processes for monosaccharide production are run at low-solid concentration (<10wt%) and use significant amounts of chemical catalysts. Biphasic CO 2-H 2O mixtures could provide a more sustainable pretreatment medium while using ...
Kinetic models have been demonstrated to be useful in on-line batch monitoring systems. The ability to monitor a reaction in real time is invaluable to the production process of industrial and pharmaceutical products. However, it is not a commonly used tec ...
The concern for the presence of micropollutants in surface waters is nowadays increasing. Among them, biocides leached from façades have demonstrated to be particularly ecotoxic. This study deals with these chemicals from a new viewpoint. Instead of analyz ...
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 ...

High-resolution X-ray computed tomography is employed to obtain the exact 3D geometrical configuration of porous anisotropic ceria applied in solar-driven thermochemical cycles for splitting H2O and CO2. The tomography data are, in turn, used in direct por ...
Monitoring, control and optimization of chemical reaction systems often requires in-depth analysis of the underlying reaction mechanisms. This dissertation investigates appropriate tools that facilitate the analysis of homogeneous and gas-liquid reaction s ...
In the framework of process optimization, the use of measurements to compensate the effect of uncertainty has re-emerged as an active area of research. One of the ideas therein is to adapt the inputs in order to track the active constraints and push certai ...
A stirred-tank reactor was built with the objective of rapid and accurate temperature control in the reaction vessel. A first-principles heat transfer model was developed for the jacketed batch system, with the jacket inlet temperature used to control the ...
The identification of reaction kinetics involves the determination of a model structure (reaction stoichiometry, rate laws for all reactions) and its corresponding parameters from experimental data. An incremental identification approach for determining th ...
Event-based control is an alternative to traditional control where new measurements are sampled only if critical events occur. This not only allows to reduce the control effort but it satisfies nowadays application requirements, such for example reduction ...
