Abstract：

This lecture will examine the vital role of catalysis in driving the circular economy, with a special focus on biomass. It will introduce the importance of catalysis in biorefinery processes and highlight recent advances in RCF lignin-first biorefinery technology, including its technoeconomic analysis (TEA) and life cycle assessment (LCA). This cutting-edge technology enables the production of a wide range of unique lignin oils and pulp. The lecture will then turn to the upgrading of both lignin oil and pulp. In the case of pulp, we will explore the challenges and opportunities associated with utilizing RCF pulp for bioethanol production through saccharification and fermentation. Lignin oil will be fractionated and analyzed with advanced chromatographic techniques to uncover detailed insights into its molecular structure. This analysis has informed the development of novel separation strategies and upgrading methods aimed at transforming individual molecules and fractions into valuable chemicals and materials for diverse applications. Green chemistry principles will be applied throughout, with a particular emphasis on designing non-regrettable substitutes for chemicals of concern. In conclusion, this presentation will offer a comprehensive exploration of the complexities of catalysis in biomass recycling, providing innovative solutions to current challenges and promoting the transition to a more sustainable, circular economy.
