Research in Multiphase Catalysis
The transition from a fossil resource-based economy to one relying on renewable energy and feedstocks does not come without multiple challenges, among which is the chemical transformation of resources for energy storage and materials.
We at the multiphase catalysis group, within the department of molecular catalysis, want to tackle the research in chemical reaction following a multiscale approach to gain a deeper understanding of the underlying phenomenology, starting from the molecular and phase behaviors up to the process level to make them more sustainable and efficient.
The development of this knowledge falls at the interface between Catalysis, Chemical Reaction Engineering and Process Intensification, to which the Green Chemistry principles must be added. For this reason, the work of this group joins the forces of Chemistry and Chemical Engineering to undertake a series of lines of work, including:
- Proposal of new reaction schemes to obtain substitute products to existing goods (e.g., fuels) from alternative starting resources.
- Study of different recycling strategies for homogeneous catalysts in multiphase systems combining computational predictions with experimental efforts.
- Development of novel reactor concepts for intensified catalysis to enhance mass transfer and catalyst recyclability.
The overall goal is to use the knowledge acquired in these aspects to conduct the implementation of process concepts at the miniplant scale with a focus on flow chemistry and on-line analytics to monitor the long-term stability of catalysts.
