This book is a ""world first"", since the furfural industry has been traditionally secretive to the point of appearing shrouded in clouds of mystery. Even renowned encyclopedic works have published but scant and often erroneous information on the subject.

Abstract

Furans are platform chemicals from biomass which have a range of functions in the production of solvents, biofuels, and monomers for industrial polymer synthesis. As the search for sustainable industrial processes makes biomass resources ever more vital, a more detailed understanding of these compounds and their industrial uses has never been more critical. « Furan Polymers and their Reactions surveys » these crucial compounds and their contributions to polymer synthesis. It discusses the biorefinery of furans, identifies furfural and 5-hydroxymethyl furfural as the key furan monomer precursors for different polymer synthetic processes, and analyzes all the major reactions furans undergo during these processes and the structures, properties and applications of the ensuing materials. The results are a vital contribution to the growing field of renewable industry.

Abstract

A concise assessment of the risks to human health and the environment posed by exposure to 2-furaldehyde. The chemical is produced commercially for industrial use in the production of resins abrasive wheels and refractories refining of lubrication oils and solvent recovery. Although 2-furaldehyde is present in many food items as a natural product or contaminant emphasis is placed on the more important risks to health that occur in occupational settings. Concerning presence in the environment the highest reported emissions are from the wood pulp industry which releases 2-furaldehyde predominant

Abstract

Clay minerals are inexpensive and available materials with a wide range of applications (adsorbent, ion exchanger, support, catalyst, paper coating, ceramic, and pharmaceutical applications, among others). Clay minerals can be easily modified through acid/basic treatments, the insertion of bulky ions or pillars into the interlayer spacing, and acid treatment, improving their physicochemical properties.Considering their low cost and high availability, clay minerals display a relatively high specific surface area in such a way that they have a great potential to be used as catalytic supports, since they can disperse expensive active phases as noble metals on the porous structures of their surfaces. In addition, the low cost of these supports allows their implementation on an industrial scale more easily than other supports, which are only feasible at the laboratory scale. Hydrotalcites (considered as anionic or basic clays) are also inexpensive materials with a great potential to be used as catalysts, since their textural properties could also be modified easily through the insertion of anions in their interlayer spacing. In the same way, these hydrotalcites, formed by layered double hydroxides, can lead to their respective mixed oxides after thermal treatment. These mixed oxides are considered basic catalysts with a high surface area, so they can also be used as catalytic support.

Abstract

The objective of this Special Issue is to provide new contributions in the area of biomass valorization using heterogeneous catalysts and focusing specifically on the structure/activity relationships of specific and important oxidation, hydrogenation, hydrodeoxygenation and biocatalytic processes. The issue emphasizes the influence of the design and morphology of the catalyst, in terms of particle size, redox and acid-base properties and catalyst stability. Finally, mechanistic studies and examples of design and optimization of industrial processes are presented.

Abstract

In the last decades, inedible lignocellulosic biomasses have attracted significant attention for being abundant resources that are not in competition with agricultural land or food production and, therefore, can be used as starting renewable material for the production of a wide variety of platform chemicals. The three main components of lignocellulosic biomasses are cellulose, hemicellulose and lignin, complex biopolymers that can be converted into a pool of platform molecules including sugars, polyols, alchols, ketons, ethers, acids and aromatics. Various technologies have been explored for their one-pot conversion into chemicals, fuels and materials. However, in order to develop new catalytic processes for the selective production of desired products, a complete understanding of the molecular aspects of the basic chemistry and reactivity of biomass derived molecules is still crucial. This Special Issue reports on recent progress and advances in the catalytic valorization of cellulose, hemicellulose and lignin model molecules promoted by novel heterogeneous systems for the production of energy, fuels and chemicals.

Abstract

Biomass has received significant attention as a sustainable feedstock that can replace diminishing fossil fuels in the production of value-added chemicals and energy. Many new catalytic technologies have been developed for the conversion of biomass feedstocks into valuable biofuels and bioproducts. However, many of these still suffer from several disadvantages, such as weak catalytic performance, harsh reaction conditions, a high processing cost, and questionable sustainability, which limit their further applicability/development in the immediate future. In this context, the esterification of carboxylic acids represents a very valuable solution to these problems, requiring mild reaction conditions and being advantageously integrable with many existing processes of biomass conversion. An emblematic example is the acid-catalyzed hydrothermal route for levulinic acid production, already upgraded to that of higher value alkyl levulinates, obtained by esterification or directly by biomass alcoholysis. Many other chemical processes benefit from esterification, such as the synthesis of biodiesel, which includes monoalkyl esters of long-chain fatty acids prepared from renewable vegetable oils and animal fats, or that of cellulose esters, mainly acetates, for textile uses. Even pyrolysis bio-oil should be stabilized by esterification to neutralize the acidity of carboxylic acids and moderate the reactivity of other typical biomass-derived compounds, such as sugars, furans, aldehydes, and phenolics. This Special Issue reports on the recent main advances in the homogeneous/heterogeneous catalytic conversion of model/real biomass components into ester derivatives that are extremely attractive for both the academic and industrial fields.
