“…Glucose isomerisation to fructose is the largest bio‐catalytic process because fructose serves as an important feedstock for the production of large numbers of chemicals and fuels via an integrated bio‐refinery approach discussed above. Fructose is not only interesting in food industries because of its sweetening property (∼2 folds sweeter than sucrose) but also serves as a precursor for the production of furfural, lactic acid (and its esters), levulinic acid, and other value added chemicals . The production of fructose by the isomerisation of glucose is limited by the thermodynamic equilibrium between the two sugar monomers at any operating temperature .…”

Bio-refinery is attracting significant interest to produce a wide range of renewable chemicals and fuels from biomass that are alternative to fossil fuel derived petrochemicals. Similar to petrochemical industries, bio-refinery also depends on solid zeolite catalysts. Acid-base catalysis plays pivotal role in producing a wide range of chemicals from biomass. Herein, the Mg framework substituted MTW zeolite is synthesized and explored in the valorisation of glucose and furfural. Bi-functional (acidic and basic) characteristics are confirmed using pyridine adsorbed FTÀ IR analysis and NH 3 and CO 2 temperatureprogrammed desorption techniques. Textural properties and morphological information are retrieved from N 2-sorption, X-ray photoelectron spectroscopy, and electron microscopy. The activity of the catalyst is demonstrated in the selective isomerisation of glucose to fructose in ethanol. Glucose is converted to methyl lactate in high yield using the same catalyst. Further, the bi-functional activity of this catalyst is demonstrated in the production of fuel precursor by the reaction of furfural and isopropanol. MgÀ MTW zeolite exhibits excellent activity in the production of all these chemicals and fuel derivative. The catalyst exhibits no significant loss in the activity even after five recycles. One simple catalyst affording three renewable synthetic intermediates from glucose and furfural will attract significant attention to catalysis researchers and industrialists.

“…Wang et al . suggested that the strong interaction between solvents and beta zeolite (Hβ) has a crucial influence on the catalytic performance, and also suggested an effective approach to improving the selectivity by regulating the solvents . It was shown that high yields and selectivity of 5‐HMF can be obtained in ionic liquids and some organic solvents, such as dimethylsulfoxide (DMSO) .…”

Millimeter size γ‐Al2O3 beads were prepared by alginate assisted sol–gel method and grafting organic groups with propyl sulfonic acid and alkyl groups as functionalized γ‐Al2O3 bead catalysts for fructose dehydration to 5‐hydroxymethylfurfural (5‐HMF). Experiment results showed that the porous structure of γ‐Al2O3 beads was favorable to the loading and dispersion of active components, and had an obvious effect on the properties of the catalyst. The lower calcination temperature of γ‐Al2O3 beads increased the specific surface area, the hydrophobicity and the activity of catalysts. Competition between the reaction of alkyl groups and ‐SH groups with surface hydroxyl during the preparation process of the catalyst influenced greatly the acid site densities, hydrophobic properties and activity of the catalyst. With an increase in the alkyl group chain, the hydrophobicity of catalysts increased obviously and the activity of the catalyst was enhanced. The most hydrophobic catalyst C16‐SO3H‐γ‐Al2O3–650°C exhibited the highest yield of 5‐HMF (84%) under the following reaction conditions: reaction medium of dimethylsulfoxide/H2O (V/V, 4:1), catalyst amount of 30 mg, temperature of 110°C and reaction time of 4 hr.

“…The tetrahedral-octahedral framework aluminum can be reversibly changed when using the amide solvents, while the GBL can enhance the turnover frequency (TOF) and surpass the furfural degradation. 93 In addition, Wang et al 94 demonstrated the use of HY zeolite with various content of Brønsted acid sites in GBL/water for the conversion of fructose into furfural and HMF. However, the Lewis acid sites presented in HY zeolite would promote the humin formation, thus decrease the HMF production.…”

In recent years, researchers have gained attention in finding new strategies for alternative renewable energy resources in reducing the dependency on fossil fuel in providing energy to the world. 5-Hydroxymethylfurfural (HMF) is one of the most promising chemicals as it is a multi-functional compound and an intermediate compound that is beneficial in numerous chemical and fuel applications. This study provides recent progress on developing high yield and selectivity of HMF using hydrothermal reaction, emphasizing the catalytic performance efficiency of the developing structured catalysts from a technical perspective. We highlighted a few critical factors and parameters in maximizing the synthesis of HMF by selectively optimizing the desired kinetic reactions, which are hydrolysis, isomerization, and dehydration of sugars, and limiting the undesired side reactions, including HMF rehydration and depolymerization. The use of different types of microporous and mesoporous catalysts provides different HMF conversion results, and by applying few parameters, including catalyst: substrate ratio, Lewis: Brønsted acid ratio, reaction temperature, and duration of reaction, can be tunable in achieving maximum HMF yield and selectivity.
