Stabilization and Upgrading of Bio-Oil Using Electrocatalytic Hydrogenation

Executive SummaryPyrolyzing biomass into bio-oil is one option to convert biomass into a useable, easily transported form with minimal inputs. However, pyrolysis-derived bio-oil contains hundreds of reactive organic compounds that are corrosive to container materials and prone to polymerization. Therefore, it is necessary to be able to rapidly convert...

Process to Improve FDCA Manufacturing

Executive SummaryAs global markets and governments are pushing to reduce fossil fuel dependencies, novel manufacturing methods of bio-based plastics are being pursued. However the cost and conversion efficiencies of creating environmentally-friendly plastics hinder the conversion from petroleum-based plastics to bio-based plastics. This novel process...

Low Cost Hydrogenation of Bio-oils

IntroductionThere is a strong need for reliable and efficient energy alternatives to non-renewable petroleum. One renewable alternative for energy is bio-oil derived by biomass pyrolysis. However, bio-oil is impractical because it is corrosive to containment materials, self-reactive, and prone to polymerization, making it unfit for use within existing...

Process for the Preparation of Lactic Acid and Glyceric Acid

Description of TechnologyMichigan State University’s invention is a process for making lactic and glyceric acid. Aqueous solutions of hexose and pentose sugars, typically glucose or fructose, are digested in the presence of strong anionic exchange resins that act as solid bases. Lactic and glyceric anions form but are bound to the ion exchange resins....
