Tim Noël Title: Innovation in photocatalysis through use of flow Abstract: Visible light photoredox catalysis has received much attention in recent years as a mild and sustainable activation mode for organic molecules. In particular, when coupled with microreactor technology, an efficient irradiation of the reaction medium is achieved. In this talk, special focus will be devoted to the development of novel photocatalytic reactions, including photon-induced hydrogen atom transfer, and we will demonstrate how these transformations benefit from being carried out in continuous photomicroreactors. Details on both engineering and chemical/catalytic aspects of continuous-flow photochemistry will be given as well. Shu-Yuan Pan Title: Systematic approach to designing precision separation processes for waste valorization Abstract: Wastes can be resources by converting them into useful products, such as agricultural amendments, chemicals (materials), and energy (fuels). To realize the circular economy system, separation processes play a critical role on the feasibility and cost-effectiveness of the business models for waste valorization. Our research team at National Taiwan University is dedicated to the development of green technologies by incorporating the Green Chemistry Principles at the beginning stage of process design. In this presentation, we will use agricultural solid wastes and organic wastewater (including anaerobic digestate) as examples. Depending on the physico-chemical properties of waste streams, we apply different mechanisms, including thermochemical, biochemical, and electrochemical separation/conversions, to extract valuable resources from wastes. We will also discuss the comprehensive performance evaluation from the aspects of engineering, environment, economic and energy. Corinne Scown Title: Designing the Bioeconomy for Deep Decarbonization Abstract: Biology offers the promise of energy-dense liquid fuels, novel materials, and opportunities to sequester atmospheric carbon dioxide. However, realizing these goals requires a step change in how fuels and chemicals are produced, and development of entirely new processes and supply chains that bring together biologists, chemists, agronomists, and engineers. Rigorous systems analysis can bring together breakthroughs across these disciplines to design feedstocks, handling strategies, conversion processes, and final products that address the needs of even the most difficult-to-decarbonize sectors of the global economy. Through technoeconomic analysis and life-cycle assessment, this talk will explore the engineering challenges and opportunities associated with decarbonizing the aviation and freight sectors. The analysis reveals the interplay between process economics and greenhouse gas mitigation, as well as potential paths to net carbon-negative fuels.
