MOVING TOWARDS MORE SUSTAINABLE CHEMICAL BUILDING BLOCKS

Design of New Strategies for the Conversion of Carbohydrates- Oral
Wednesday PM

Symposium Organizer: Katalin Barta (University of Groningen, The Netherlands); Pieter Bruijnincx (Utrecht University)

The design of catalysts will have to accommodate the increased level of functionality present in the renewable biopolymers. Compared to petroleum where the goal was the selective addition of functionality, here new creative solutions are needed for depolymerization, (partial) defunctionalization and bond cleavage reactions. Especially the non-­edible fraction of renewables, lignocellulose (as well as triglycerides and other plant components) that can be part of agricultural and forestry waste materials harbors much potential as feedstock for the future, sustainable chemical enterprise. This session is comprised of presentations about the direct conversion of cellulose and the chemical conversion of the most important chemicals.

Conversion of Renewables: Catalysis, Methods and Technologies- Oral
Tuesday PM

Symposium Organizer: Katalin Barta (University of Groningen, The Netherlands); Pieter Bruijnincx (Utrecht University)

Compared to petroleum where the goal was the selective addition of functionality, here new creative solutions are needed for depolymerization, (partial) defunctionalization and bond cleavage reactions. Especially the non-­edible fraction of renewables, lignocellulose (as well as triglycerides and other plant components) that can be part of agricultural and forestry waste materials harbors much potential as feedstock for the future, sustainable chemical enterprise. The session will discuss polymer building blocks from fatty acids, platform chemicals and glycerol.

Design of New Strategies for the Conversion of Lignin- Oral
Wednesday AM

Symposium Organizer: Katalin Barta (University of Groningen, The Netherlands); Pieter Bruijnincx (Utrecht University)

There is urgent need to identify central platform chemicals not only for the sugar fraction, but also for lignin that is the largest renewable source of aromatics on the planet. Over the past decade, tremendous advances have been achieved in multiple related areas, but more progress is needed towards the economically viable and fully sustainable implementation of new chemical routes starting from specific classes of renewable starting materials. It is imperative that the new catalysts designed for these purposes are based on earth-­abundant materials, are atom economic and energy efficient, and contribute to the reduction of waste by better design. This session is comprised of oral pretensions regarding selective bond cleavage and homogeneous catalysis, heterogeneous catalysis, lignin to BTX, lignin to functionalized aromatics, thermal approaches

CO2 Utilization by Design: From Molecular Catalysts to Surface Chemistry- Oral
Tuesday AM & PM

Symposium Organizers: Gonghu Li (University of New Hampshire), Jonas Baltrusaitis (Lehigh University)

Carbon dioxide (CO2) is a renewable C1 feedstock for the production of chemicals, materials and fuels.  Chemical reduction of CO2 has attracted extensive research interests from scientists and engineers from all over the world.  This session will feature talks by researchers working in the field of photocatalytic and electrocatalytic CO2 reduction using molecular, heterogeneous, and hybrid systems.  This session will also serve as an educational platform to broadly disseminate knowledge and concepts of sustainability and green chemistry/engineering.
