Book excerpt: In Chapter 4, biomass-derived platform chemicals are used to produce bio-lubricant base oils. Our strategy involves coupling 12-tricosanone, obtained from bioderived fatty acids, with furfural, a C-5 species, obtained from hemicellulose, to form a highly branched bio-lubricant base oil. I show that the viscous properties of the final product are comparable to commercial petroleum-derived Group III and Group IV base oils.

Download or read book Acid catalyzed Reactions for the Production of Platform Chemicals from Cellulosic Biomass in Liquid Phase Systems written by and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid catalysts are used in many applications focused on biomass conversion. Liquid phase processing serves as one of the primary routes to produce platform chemicals from cellulosic biomass. The fundamental challenge with producing products by acid catalyzed reactions is that undesired carbonaceous species (i.e. humins) form by both parallel and series reactions, which limit the selectivity to desired products. The goal of this research is to study the fundamental acid-catalyzed chemistry to produce biomass-derived platform chemicals in liquid phase systems. We use an integrated approach that includes: (1) understanding the fundamental chemistry and reaction pathways through kinetic studies with homogeneous acid catalysts and (2) elucidating the relationship between the properties of solid acid catalysts and their correlation with activity and selectivity of acid catalyzed reactions. We have developed kinetic models for the aqueous phase production of furfural and hydroxymethylfurfural (HMF) from xylose and glucose respectively using homogeneous catalysts. The dehydration chemistry to form these furanic derivatives from carbohydrates is distinguished by a relatively high activation energy step (ca. 120-160 kJ/mol). Undesired humins also form, which typically have lower activation barriers (i.e. 50-70 kJ/mol). Product selectivity can be tuned by altering the Brønsted to Lewis acid site ratio of the acid catalysts. Lewis acid sites decrease furfural and HMF selectivity, as they mainly catalyze the formation of isomerization byproducts and humins. Brønsted acid sites catalyze the dehydration step to produce furfural and HMF. These findings are true for both heterogeneous and homogeneous catalysts. Accordingly, in our studies with solid acid metal(IV) phosphate catalysts, we show that zirconium phosphate with a P/Zr molar ratio of 2 is favorable for levulinic acid production from glucose due to its inherently high surface area and enhanced Brønsted acidity. We have also discovered that HMF can selectively be produced from cellulose under mild reaction conditions in polar aprotic solvents (i.e. tetrahydrofuran) without the presence of water. This pathway goes through a levoglucosan intermediate. The turnover frequency for cellulose conversion increases as the water content in the solvent decreases, with conversion rates in tetrahydrofuran being more than twenty times higher than those in water.

Download or read book Bridging Heterogeneous and Homogeneous Catalysis written by Can Li and published by John Wiley & Sons. This book was released on 2014-04-03 with total page 860 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two main disciplines in catalysis research -- homogeneous and heterogeneous catalysis. This is due to the fact that the catalyst is either in the same phase (homogeneous catalysis) as the reaction being catalyzed or in a different phase (heterogeneous catalysis). Over the past decade, various approaches have been implemented to combine the advantages of homogeneous catalysis (efficiency, selectivity) with those of heterogeneous catalysis (stability, recovery) by the heterogenization of homogeneous catalysts or by carrying out homogeneous reactions under heterogeneous conditions. This unique handbook fills the gap in the market for an up-to-date work that links both homogeneous catalysis applied to organic reactions and catalytic reactions on surfaces of heterogeneous catalysts. As such, it highlights structural analogies and shows mechanistic parallels between the two, while additionally presenting kinetic analysis methods and models that either work for both homogeneous and heterogeneous catalysis. Chapters cover asymmetric, emulsion, phase-transfer, supported homogeneous, and organocatalysis, as well as in nanoreactors and for specific applications, catalytic reactions in ionic liquids, fluorous and supercritical solvents and in water. Finally, the text includes computational methods for investigating structure-reactivity relations. With its wealth of information, this invaluable reference provides academic and industrial chemists with novel concepts for innovative catalysis research.
