“…[40,[108][109][110][111] In this respect, continuous flow processing is essential. Many biomass transformations are performed in multiphase (e. g., liquid-liquid or gas-liquid) systems with homogeneous or heterogeneous catalysts, where a proper reactor design is essential for its optimal performance.…”

“…Greener and more efficient processes need to be developed in order to make the production of chemicals from biomass a feasible alternative to petroleum. [40,[108][109][110][111] In this respect, continuous flow processing is essential. Flow operation is more desirable than batch operation for the high-throughput production of chemicals as it generates less waste and requires less off-time (necessary for start-up and maintenance).…”

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.

“…Over the past century, petroleum has been the primary raw material utilized for the production of fine and bulk chemicals. However, with the rapidly growing demand for unsustainable petroleum resources, lignocellulosic materials are drawing increasing attention as a renewable and lower carbon-footprint feedstock. , Lignocellulose is mainly composed of cellulose (∼40 wt %), hemicellulose (∼30 wt %), and lignin (∼20 wt %) with extractives and inorganic components comprising the remainder . Glucose and xylose are the main subunits of cellulose and hemicellulose.…”

Kinetics of Maleic Acid and Aluminum Chloride Catalyzed Dehydration and Degradation of Glucose

We report the positive effect of maleic acid, a dicarboxylic acid, on the selectivity of hexose dehydration to 5hydroxymethyfurfural (HMF) and subsequent hydrolysis to levulinic and formic acids. We also describe the kinetic analysis of a Lewis acid (AlCl 3 ) alone and in combination with HCl or maleic acid to catalyze the isomerization of glucose to fructose, dehydration of fructose to HMF, hydration of HMF to levulinic and formic acids, and degradation of these compounds to humins. The results show that AlCl 3 significantly enhances the rate of glucose conversion to HMF and levulinic acid in the presence of both maleic acid and HCl. In addition, the degradation of HMF to humins, rather than levulinic and formic acids, is reduced by 50% in the presence of maleic acid and AlCl 3 compared to HCl combined with AlCl 3 . The results suggest different reaction mechanisms for the dehydration of glucose and rehydration of HMF between maleic acid and HCl.

“…Therefore, the process development is expected to be fast and straightforward. However, this approach requires a proper design of the gas-liquid-distributor [158]. Several feasible designs have been presented in the literature [159][160][161][162][163][164][165], but functionality has not been proven at the industrial scale.…”

This work presents an advanced reactor selection strategy that combines elements of a knowledge-based expert system to reduce the number of feasible reactor configurations with elaborated and automatised process simulations to identify reactor performance parameters. Special focus was given to identify optimal catalyst loadings and favourable conditions for each configuration to enable a fair comparison. The workflow was exemplarily illustrated for the Ru/C-catalysed hydrogenation of arabinose and galactose to the corresponding sugar alcohols. The simulations were performed by using pseudo-2D reactor models implemented in Aspen Custom Modeler® and automatised by using the MS-Excel interface and VBA. The minichannel packings, namely wall-coated minichannel reactor (MCWR), minichannel reactor packed with catalytic particles (MCPR), and minichannel reactor packed with a catalytic open-celled foam (MCFR), outperform the conventional and miniaturised trickle-bed reactors (TBR and MTBR) in terms of space-time yield and catalyst use. However, longer reactor lengths are required to achieve 99% conversion of the sugars in MCWR and MCPR. Considering further technical challenges such as liquid distribution, packing the reactor, as well as the robustness and manufacture of catalysts in a biorefinery environment, miniaturised trickle beds are the most favourable design for a production scenario of galactitol. However, the minichannel configurations will be more advantageous for reaction systems involving consecutive and parallel reactions and highly exothermic systems.
