THF co-solvent enhances hydrocarbon fuel precursor yields from lignocellulosic biomass

James Sherwood is a guest web-writer for Green Chemistry. James is a research associate in the Green Chemistry Centre of Excellence at the University of York. His interests range from the certification and application of bio-based products, to the understanding of solvent effects in organic synthesis.

Charles Wyman and colleagues have demonstrated a highly effective lignocellulosic bio-refinery model, producing unrivalled quantities of furfural, 5-hydroxymethylfurfural (HMF), and levulinic acid as products. Proposed as a basis for the production of renewable fuels, the furan derivatives generated by this process are also a promising platform onto many other intriguing bio-based molecules. Additionally, more than 90% of the lignin contained within the maple wood feedstock was reclaimed, making the process as a whole exceptionally appealing.

Instead of the typical acidified aqueous media often used, the hydrolysis of the lignocellulose feedstock (and subsequent sugar dehydration) was enhanced with the addition of the potentially renewable solvent tetrahydrofuran. The organic solvent increased yields of HMF by an order of magnitude over what could be obtained otherwise in a one-pot reaction conducted at 170 °C. Under these optimised conditions, 87% of the total pentose (C5) sugar content was accountable in the form of furfural, while the hexose (C6) sugar content was converted from cellulose into HMF (in up to yields of 21% of the theoretical maximum), levulinic acid (up to 40%), and free sugars. The authors believe this represents a key step towards achieving commercial viability for sustainable, sugar derived bio-fuels.

    Wow! This blog looks exactly like my old one! It’s on a entirely different subject but it has pretty much the
    same layout and design. Excellent choice of colors!
