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 exist...

Recovery of Glycols from Aqueous Solutions

IntroductionGlycols, in particular ethylene glycol, are used as antifreeze in automobiles, are a main constituent of plastics such asf poly(ethylene terephthalate) or PET, polyesters, and polyurethanes. The combined utility of glycols represents a multibillion dollar market. These compounds are typically formed in multistep processes in dilute aq...

Catalysts and Process for Hydrogenolysis of Sugar Alcohols to Polyols

Description of TechnologyMetal-catalyzed cleavage of polyols (MCCP) is a novel technology for preparing low molecular weight polyols such as ethylene glycol and propylene glycol from high molecular weight polyols. Specifically, MCCP is a novel route for breaking apart these sugars (C6 and C5) using a metal-catalyzed, alkaline cleavage of sugar alco...

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 exchang...

High Yield Glycerol to Propylene Glycol Conversion Process

IntroductionThe increased production of biodiesel has resulted in a concomitant increased availability of glycerol, a byproduct of the production process. As a result the price of glycerol has experienced a sharp downward spiral. Challenges have confronted biodiesel producers who have pursued Glycerol conversion to the Propylene Glycol, a more desi...
