Researchers at DOE’s Ames Laboratory are experimenting with chemical reactions that will provide an economical method of deconstructing lignin into stable, readily useful components.  Lignin is the second largest renewable carbon source on the planet, making it of interest to researchers focused on developing biofuels and bioproducts.  Currently, lignin is processed via pyrolysis or the use of an acid and high heat.  Both processes are inefficient and require high energy consumption.  Igor Slowing, an expert in heterogeneous catalysis, and his team are focused on developing a method of processing lignin at low temperature and pressure.  To achieve this goal, the team combined the decomposition and stabilization process into a single step using mild conditions and a multi-functional catalyst, specifically phosphate-modified ceria.  According to Slowing, the two processes appear to work synergistically at a lower temperature.  Following the promising results, the team aims to achieve lignin deconstruction using hydrogen from a renewable source.
