FOCUS

The overall objective for this project is to demonstrate cost-effective production of high-value green octinoxate and vanillin and green epoxies from extracted lignin as part of a fuel production system. The research team will utilize a two-stage process that first removes hydroxycinnamic acids from the lignin using a mild base extraction followed by solvent liquefaction to produce phenolic oil, solid residue (char) and non-condensable gases. The hydroxycinnamic acids, specifically ferulic and coumaric acids, will be recovered and converted to high-value chemicals. The target molecules are Octinoxate, vanillin, and hydroxy cinnamate based epoxies. The remaining phenolic oil will be upgraded to phenolic monomers and/or aromatic hydrocarbon selectively, as these have been identified as key high value-added monomers for the chemical industry[1]. This study will focus on converting switchgrass-derived lignin co-product from the Renmatix Plantroseā„¢ supercritical hydrolysis process.
