Key research themes

1. How can process intensification strategies improve reactor performance and safety in chemical reaction engineering?

This research area investigates the principles, methodologies, and applications of process intensification (PI) to enhance chemical reactor performance, focusing on achieving higher conversion, selectivity, process efficiency, and safety. It encompasses innovative reactor designs such as micro- and milli-reactors, integration of reaction and separation, novel energy sources, and dynamic operation modes. Understanding and applying PI principles matter as they enable the processing of challenging reactions under safer and more sustainable conditions, reduce equipment size and costs, and open novel process windows.

Key finding: This comprehensive review establishes four guiding principles for PI derived from maximizing intramolecular and intermolecular effectiveness, uniform process experience for molecules, optimizing driving forces through... Read more

2. What are the emerging approaches for integrating renewable energy and alternative carbon sources into chemical reaction engineering towards sustainable chemical production?

This theme focuses on adapting chemical reaction engineering to incorporate renewable energy inputs and utilize non-fossil carbon feedstocks to achieve sustainability goals. It involves developing new reactors, catalytic materials, process assessment tools, and methodologies that accommodate the unique challenges posed by intermittent energy supply, novel reaction pathways, and novel feedstocks like CO2 and biomass-derived molecules. The theme is crucial as the chemical industry transitions away from fossil fuels and adopts low-carbon technologies requiring innovative reactor and process engineering.

Key finding: The review highlights that utilizing renewable energy and alternative carbon sources necessitates not only novel catalytic materials but also advanced reactor and process design tools integrating thermodynamics, kinetics, and... Read more

3. How can catalyst design and mechanistic understanding improve selectivity and efficiency in homogeneous catalytic processes such as methanol carbonylation?

This research area addresses advances in catalyst modification, ligand design, and mechanistic modeling to optimize homogeneous catalytic processes pivotal for acetic acid production and other industrial chemicals. It explores how the incorporation of specific ligands impacts catalytic activity, solubility, and reaction kinetics, while mechanistic insights guide the rational design of catalysts and operational strategies. Improving such catalysts is vital to enhance process economics, reduce by-products, and lower environmental impact.

Key finding: The study experimentally compares Rhodium-based homogeneous catalysts appended with triethylphosphine (3EP) and triphenylphosphine (3PP) ligands versus Rh₃I catalyst for methanol carbonylation. It finds that 3PP ligand... Read more
