Research is exploring how to add value to lignin by breaking it down into small molecules that are structurally similar to oxygenated hydrocarbons. These renewable chemicals are key components in many industrial processes and products, but they are traditionally sourced from non-renewable petroleum.
Lignin, a complex organic polymer, is one of the main components of wood, providing structural support and rigidity to make trees strong enough to withstand the elements. When transforming wood into paper, lignin is a key ingredient that must be removed and often becomes waste.
With collaborators at ORNL, Foston used neutron scattering to study how lignin interacts with solvents and catalysts during its disassembly under reaction conditions, including high temperature and pressure. ORNL's advanced facilities allowed researchers to observe the reaction process in real time to improve their catalyst and further streamline reaction systems for lignin depolymerization.
