“…[343] 2-MTHF can be produced from biomass and in particular lignocellulosic material via either furfural or levulinic acid as intermediates. [37,38,[344][345][346][347] Low yields of 2-MTHF are,however, obtained in general from the complete hydrogenation of furfural because of the formation of many by-products including 2-pentanone and THF (by ad ecarbonylation reaction). Theelementary reaction steps of the hydrogenation of furfural have been described in detail by Zheng et al,w ho considered 2-MF in this case to be the intermediate precursor in the preparation of 2-MTHF (Scheme 14 b).…”

Sustainably produced biofuels, especially when they are derived from lignocellulosic biomass, are being discussed intensively for future ground transportation. Traditionally, research activities focus on the synthesis process, while leaving their combustion properties to be evaluated by a different community. This Review adopts an integrative view of engine combustion and fuel synthesis, focusing on chemical aspects as the common denominator. It will be demonstrated that a fundamental understanding of the combustion process can be instrumental to derive design criteria for the molecular structure of fuel candidates, which can then be targets for the analysis of synthetic pathways and the development of catalytic production routes. With such an integrative approach to fuel design, it will be possible to improve systematically the entire system, spanning biomass feedstock, conversion process, fuel, engine, and pollutants with a view to improve the carbon footprint, increase efficiency, and reduce emissions.

“…Luckily, many common solvents, e.g., acetone [13], methanol [14], ethanol [15], butanol [16], isopropanol [17], ethyl acetate [18], and 2-methyltetrahydrofuran [19], may be produced from renewable feedstocks rather than from petroleum [20]. Additionally, the list of preferably used solvents [20,21] includes water [22], acetone [23], ethanol [24], 2-propanol [25], 1-propanol [26], methanol [27], 1-butanol [28].…”

When considering cellulose (UFC100) modification, most of the processes employ various solvents in the role of the reaction environment. The following article addresses a solvent-free method, thermal drying, which causes a moisture content decrease in cellulose fibers. Herein, the moisture content in UFC100 was analyzed with spectroscopic methods, thermogravimetric analysis, and differential scanning calorimetry. During water desorption, a moisture content drop from approximately 6% to 1% was evidenced. Moreover, drying may bring about a specific variation in cellulose’s chemical structure. These changes affected the cellulose-filled polymer composite’s properties, e.g., an increase in tensile strength from 17 MPa for the not-dried UFC100 to approximately 30 MPa (dried cellulose; 24 h, 100 °C) was observed. Furthermore, the obtained tensile test results were in good correspondence with Payne effect values, which changed from 0.82 MPa (not-dried UFC100) to 1.21 MPa (dried fibers). This raise proves the reinforcing nature of dried UFC100, as the Payne effect is dependent on the filler structure’s development within a polymer matrix. This finding paves new opportunities for natural fiber applications in polymer composites by enabling a solvent-free and efficient cellulose modification approach that fulfils the sustainable development rules.

“…2‐MTHF kann aus Biomasse und dabei insbesondere aus Lignozellulosematerial entweder über Furfural oder über Lävulinsäure als Zwischenprodukt hergestellt werden . Für 2‐MTHF, das durch vollständige Hydrierung von Furfural hergestellt wird, werden allerdings allgemein niedrige Ausbeuten erzielt, u. a. aufgrund der ausgeprägten Bildung von Nebenprodukten, einschließlich 2‐Pentanon oder THF (durch Decarbonylierungsreaktion).…”

Synthese, motorische Verbrennung, Emissionen: Chemische Aspekte des Kraftstoffdesigns

Nachhaltig produzierte Biokraftstoffe, die auf Basis von Lignozellulose zugänglich sind, werden in Energieszenarien für Mobilität und Transport der Zukunft intensiv diskutiert. Traditionell konzentrieren sich die Forschungsaktivitäten in den Naturwissenschaften dabei auf den Syntheseprozess, während die anschließende Bewertung der Verbrennungseigenschaften anderen Forschungsgebieten überlassen wird. Dieser Aufsatz verfolgt mit der gemeinsamen Betrachtung der motorischen Verbrennung und der Kraftstoffsynthese einen integrativen Ansatz, bei dem die chemischen Aspekte im Vordergrund stehen. Dabei wird deutlich, dass das fundamentale Verständnis des Verbrennungsvorgangs maßgeblich dazu beitragen kann, Designkriterien für die Molekülstruktur möglicher Kraftstoffkandidaten abzuleiten, um so Ziele für die Analyse von Synthesewegen und die Entwicklung katalytischer Produktionswege zu definieren. Dieser integrative Ansatz des “Kraftstoffdesigns” umfasst die gesamte Kette der Energiekonversion ausgehend vom Rohstoff über Herstellungsprozess, Kraftstoff und Motor bis hin zur Schadstoffemission. Dies ermöglicht eine systematische Optimierung des Gesamtsystems mit dem Ziel, die Kohlenstoffbilanz zu verbessern, die Effizienz zu erhöhen und die Emissionen zu verringern.
