“…By the centrifugal forces high mass/heat transfer rates are obtained. [158] It has been applied to biomass transformation processes, [159] such as biodiesel synthesis, [160] biomass pyrolysis, [161] and the sugar dehydration to furans (e. g., HMF and furfural). [128,129] Enhanced heat/mass transfer can be also obtained in continuous flow microreactors that consist of reaction channels with diameters on the order of ca.…”

Biomass as a renewable and abundantly available carbon source is a promising alternative to fossil resources for the production of chemicals and fuels. The development of biobased chemistry, along with catalyst design, has received much research attention over recent years. However, dedicated reactor concepts for the conversion of biomass and its derivatives are a relatively new research field. Continuous flow microreactors are a promising tool for process intensification, especially for reactions in multiphase systems. In this work, the potential of microreactors for the catalytic conversion of biomass derivatives to value-added chemicals and fuels is critically reviewed. Emphases are laid on the biphasic synthesis of furans from sugars, oxidation and hydrogenation of biomass derivatives. Microreactor processing has been shown capable of improving the efficiency of many biobased reactions, due to the transport intensification and a fine control over the process. Microreactors are expected to contribute in accelerating the technological development of biomass conversion and have a promising potential for industrial application in this area.

“…Recently, mechanochemistry has been widely applied in chemical and material synthesis with the unique advantage of enabling efficient solid-state reactions and the ability to directly convert various recalcitrant feedstocks. [61][62][63][64][65][66][67][68][69][70][71][72][73][74] A series of studies transforming biomass in a solvent-free way have been demonstrated. For example, cellulose was converted to watersoluble oligomers by both mineral acids and solid acids in a ball milling process, 75,76 while lignin was decomposed similarly in the presence of a base.…”

“…As alternatives to conventional mineral acids (e.g., H 2 SO 4 and HCl), the hydrolysis of cellulose with solid acid catalysts is perceived to be a more environmentally benign approach as their use simplifies downstream processing . In this context, ILs containing acidic units may potentially dissolve and selectively deconstruct biomass while simultaneously catalyzing reactions .…”

Direct Conversion of Mono‐ and Polysaccharides into 5‐Hydroxymethylfurfural Using Ionic‐Liquid Mixtures

Platform chemicals are usually derived from petrochemical feedstocks. A sustainable alternative commences with lignocellulosic biomass, a renewable feedstock, but one that is highly challenging to process. Ionic liquids (ILs) are able to solubilize biomass and, in the presence of catalysts, convert the biomass into useful platform chemicals. Herein, we demonstrate that mixtures of ILs are powerful systems for the selective catalytic transformation of cellulose into 5-hydroxymethylfurfural (HMF). Combining ILs with continuous HMF extraction into methyl-isobutyl ketone or 1,2-dimethoxyethane, which form a biphase with the IL mixture, allows the online separation of HMF in high yield. This one-step process is operated under relatively mild conditions and represents a significant step forward towards sustainable HMF production.
