Download or read book The Selective Production of Biomass Derived Chemicals Using Heterogeneous Catalysts written by and published by . This book was released on 2016 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of heterogeneous catalytic technologies for the selective conversion of lignocellulosic biomass to platform molecules such as 5-hydroxymethylfurfural (HMF) and 2,5-dihydroxymethylfurfural (DHMTHF) has been studied. Supported metal catalysts were used for the selective hydrogenation of HMF to DHMTHF. Small trace amounts of acid in the aqueous solution with HMF feed was found to play an important role in determining the selectivity for the hydrogenation of HMF to DHMTHF. DHMTHF, tetrahydrofuran (THF), gamma valerolactone (GVL), and other aprotic miscible organic solvents were mixed with water to form a monophasic co-solvent. These co solvents systems were found to be separation friendly solvents compared to dimethyl sulfoxide (DMSO) and other higher boiling organic solvents that are selective for HMF production. The monophasic co-solvents investigated were also selective for the production of HMF from fructose using Brønsted acid catalysts; additionally, an increase in the rate of reaction, compared to water, was observed. Fructose tautomerization favors the furanose form in the mixed solvent, relative to water alone, explaining at least part of the rate enhancement. The use of co-solvents and acid-functionalized ordered mesoporous silica catalysts show high selectivity for HMF from fructose. The synthesis to intercalate PVP on the catalyst surface was developed to achieve high selectivities previously achieved only with ionic liquids. The high concentration of pyrrolidone in the confined space of the pores favors the furanose tautomers which can be easily dehydrated to HMF. Thus, the reaction environment within the catalyst has been designed to favor the desired product. Solvent reactivity studies for homogenous base, homogenous Lewis acid, solid bases, and solid Lewis acids for glucose isomerization to fructose were conducted. The small addition of miscible organic solvent led to a drop of reactivity compared to that of pure water. However, with increasing GVL concentration, the reactivity increased as well. Benzene-bridged PMOs doped with Lewis acidic Sn sites were readily and rapidly synthesized. These thermally robust, hydrophobic materials catalyze the selective isomerization of glucose to fructose in co-solvent systems. Brønsted acid sites were incorporated and a bifunctional PMO was synthesized for tandem conversion of glucose to fructose and its dehydration to HMF.

Available in PDF, EPUB and Kindle. Book excerpt: The use of solid catalysts for the upgrade of renewable sources gives the opportunity to combine the two main cores of green chemistry, that is, on the one hand, the set-up of sustainable processes and, on the other, the use of biomass-derived materials. Solid catalysts have taken on a leading role in traditional petrochemical processes and could represent a key tool in new biorefinery-driven technologies. This book will cover topics related to the preparation and use of heterogeneous catalytic systems for the transformation of renewable sources, as well as of materials deriving from agro-industrial wastes and by-products. At the same time, the ever-increasing importance of bioproducts, due to the acceptance and request of consumers, makes the upgrade of biomass into chemicals and materials not only an environmental issue, but also an economical advantage.

This book was released on 2022-01-05 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: HANDBOOK of BIOMASS VALORIZATION for INDUSTRIAL APPLICATIONS The handbook provides a comprehensive view of cutting-edge research on biomass valorization, from advanced fabrication methodologies through useful derived materials, to current and potential application sectors. Industrial sectors, such as food, textiles, petrochemicals and pharmaceuticals, generate massive amounts of waste each year, the disposal of which has become a major issue worldwide. As a result, implementing a circular economy that employs sustainable practices in waste management is critical for any industry. Moreover, fossil fuels, which are the primary sources of fuel in the transportation sector, are also being rapidly depleted at an alarming rate. Therefore, to combat these global issues without increasing our carbon footprint, we must look for renewable resources to produce chemicals and biomaterials. In that context, agricultural waste materials are gaining popularity as cost-effective and abundantly available alternatives to fossil resources for the production of a variety of value-added products, including renewable fuels, fuel components, and fuel additives. Handbook of Biomass Valorization for Industrial Applications investigates current and emerging feedstocks, as well as provides in-depth technical information on advanced catalytic processes and technologies that enable the development of all possible alternative energy sources. The 22 chapters of this book comprehensively cover the valorization of agricultural wastes and their various uses in value-added applications like energy, biofuels, fertilizers, and wastewater treatment. Audience The book is intended for a very broad audience working in the fields of materials sciences, chemical engineering, nanotechnology, energy, environment, chemistry, etc. This book will be an invaluable reference source for the libraries in universities and industrial institutions, government and independent institutes, individual research groups, and scientists working in the field of valorization of biomass.
