Inedible, lignocellulosic biomass has been recognized as most promising renewable resource for the production of high value bio-chemicals. The pretreated biomass or isolated cellulose is a biopolymer of glucose used as a stating material for the synthesis of 5-hydroxymethylfurfural (HMF). HMF is listed among the top 10 bio-based chemicals by USA Department of Energy and it acts as feedstock for deriving a number of commodity products (Bonzell and Petersen, 2010, Green Chem. 12, 539). In present review, we have systematically summarized the catalytic reaction for the synthesis of HMF from pretreated biomass/isolated cellulose using green processes. Further, through catalytic approach, HMF is translated into industrial important chemicals (2,5-diformylfuran, furan-2,5-dicarboxylicacid, 2,5-furandimethanol, furfuraylalcohol, etc) or high calorific value biofuel (2,5-dimethylfuran, 2,5-dimethyltetrahydrofuran, 2,5-bis(alkoxymethyl)furans, etc). In the profitable scale of HMF production, levulinic acid (LA) is generated as a major byproduct. Besides HMF, this review also outlines the catalytic strategy for the conversion of LA to industrially important chemicals along with the biofuel additives. Finally, the bio-toxicity of synthesized chemicals, which connected into different functional groups have been summarized to meet the criteria of the green technology for commercialization.

Apart from a short introduction that describes biomass and its platform chemicals; this manuscript endevours to analyze and classify the enormous literature that has been generated for biomass conversion over a new class of heterogeneous catalysts metal?organic frameworks (MOFs); the recent progress of sugar conversion over MOFs based catalysis into valuable chemicals such as 5-hydroxymethylfurfural (5-HMF) and the subsequent secondary platform chemicals such as 2,5-dimethylfuran, ethyl levulinate and lactic acid was investigated. The smart selection of MOFs? building units and reaction solvents are critically discussed. The catalytic potential of different MOFs and composite MOFs was also investigated by demonstrating their remarkable performance with salutary examples relevant to biomass catalytic conversions into initial and secondary platform chemicals. This review also gives a state-of-the-art for the corresponding reaction kinetics and reaction mechanisms regarding the discussed sugar conversion.

In response to the awareness of limited fossil resources and environmental concerns, catalytic conversion of renewable lignocellulose biomass to value-added chemicals and fuels is of great significance and attractive for sustainable chemistry. Division of Biomass Conversion and Bio-Energy attached to Dalian National Laboratory for Clean Energy has devoted themselves to valorization of lignocellulose biomass since launched in 2011. Our research interests focus on breeding of biomass resources (inulin and microalgae), exploration of catalytic and biological technologies, and production of energy chemicals and fuels. Although lignocellulose biomass is renewable and abundant, the way of utilization should be reasonable according to its structural characteristics in view of efficiency and economy. In this review, to celebrate the DICP’s 70th anniversary, we will highlight the major fundamental advances in DICP about the conversion of lignocellulose to value-added chemicals and liquid fuels. Particular attention will be paid to the transformation of cellulose and its derivatives to glycols, acids and nitrogen-containing chemicals, hemicellulose-derived platform molecule furfural to jet fuels and lignin to aromatics using catalytic technologies.

Currently, highly efficient transformation of abundant and low-cost renewable raw biomass into high-quality biofuels and important chemicals is one of the most promising solutions to the current energy crisis, rapid consumption of fossil resources, increasing emission of greenhouse gases and serious environmental pollution. Here, convertible production of promising 2,5-dimethylfuran (DMF) and 2,5-dimethyltetrahydrofuran (DMTHF) biofuels was achieved successfully via green catalytic transfer hydrogenolysis of biomass-derived 5-hydroxymethylfurfural (HMF) using a nitrogen-doped carbon (NC)-decorated copper-based catalyst with cyclohexanol as hydrogen source. DMF or DMTHF with high yield of 96.1% or 94.6% was produced convertibly through simply modulating reaction time. Extensive characterizations revealed that appropriate surface base sites on the catalyst could efficiently promote the activation of alcohol hydroxyl in cyclohexanol and the subsequent release of active hydrogen species, while highly dispersed surface Cu0 nanoparticles and electrophilic Cu+ species were beneficial to the hydrogen transfer and the activation of both the carbonyl group and the hydroxyl group in HMF, respectively. Moreover, as-fabricated NC-decorated Cu-based catalyst presented high stability without obvious loss of catalytic performance after five consecutive cycles, due to the strong interaction between the support and active metal species. Such non-noble metal catalyst has a promising industrial application in the production of valuable biomass fuels.

1,6-Hexanediol (1,6-HDO) was effectively prepared from 5-hydroxymethylfurfural (HMF) over double-layered catalysts of Pd/SiO2 + Ir-ReOx/SiO2 in a fixed-bed reactor. Under optimal reaction conditions (373 K, 7.0 MPa H2, in solvent mixtures of 40% water and 60% tetrahydrofuran (THF)), 57.8% yield of 1,6-HDO was obtained. The double-layered catalysts loaded in double-layered beds showed much superior performance compared to that of a single catalyst of Pd-Ir-ReOx/SiO2, even when the same amount of active components were used in the catalysts. The reaction solvent significantly affected product distributions, giving a volcano-shape plot for the 1,6-HDO yield as a function of the ratio of water to THF. Br°nsted acidic sites were generated on the catalyst in the presence of water which played determining roles in 1,6-HDO formation. A high pressure of H2 contributed to 1,6-HDO formation by depressing the over-hydrogenolysis of reaction intermediates and products to form hexane and hexanol. The reaction route was proposed for HMF conversion to 1,6-HDO on the basis of conditional experiments.

Biomass-derived 5-hydroxymethylfurfural (HMF) has been emerged as a key platform chemical for the production of fine chemicals and liquid fuels. The direct transformation of cellulose and lignocellulosic biomass into HMF in ionic liquids and organic solvents is most desired in terms of process economics and sustainability. The focus of this review is purely on the HMF production from cellulose and lignocelluloses and mechanistic aspects of HMF formation in order to bridge the gap in understanding the factors responsible for selective conversion and selection of catalyst. Additionally, present review is devoted exclusively to the latest developments, namely microwave-assisted degradation of cellulose to HMF, application of solid acid and ionic-liquid catalysis to address their effectiveness for HMF production. Approaches for the cellulose transformation into HMF are especially emphasized in order to explore newer avenues of biomass as renewable feedstock for energy and chemicals.

Disclosed herein are methods for synthesizing 1,2,5,6-hexanetetrol (HTO), 1,6 hexanediol (HDO) and other reduced polyols from C5 and C6 sugar alcohols or R glycosides. The methods include contacting the sugar alcohol or R-glycoside with a copper catalyst, most desirably a Raney copper catalyst with hydrogen for a time, temperature and pressure sufficient to form reduced polyols having 2 to 3 fewer hydoxy groups than the starting material. When the starting compound is a C6 sugar alcohol such as sorbitol or R-glycoside of a C6 sugar such as methyl glucoside, the predominant product is HTO. The same catalyst can be used to further reduce the HTO to HDO.

The production of chemicals directly from sugars is an important step in biomass conversion. Herein, tetrahydro-2,5-furandimethanol (THFDM), obtained from fructose, is formed by using a combination of acid and hydrophobic Ru/SiO2 in a water/cyclohexane biphasic system. Two key factors enable the high selectivity towards THFDM: modifying the hydrogenation catalyst so that it has hydrophobic properties, and the continuous hydrogenation of generated 5-(hydroxymethyl)furfural in the cyclohexane phase. Moreover, the selectivity towards THFDM is found to depend strongly on the acid catalyst used. Divide and conquer: A method for direct catalytic conversion of fructose to tetrahydro-2,5-furandimethanol (THFDM) via 5-(hydroxymethyl)furfural (HMF) is reported. High selectivity towards THFDM is achieved by using a catalyst combination of acid and a hydrophobic ruthenium catalyst (Ru/SiO2-TM) in a water/cyclohexane biphasic system by continuous hydrogenation of generated HMF. The use of the hydrophobic Ru/SiO2-TM is the key, as it prevents hydrogenation of fructose to mannitol and sorbitol in the water phase.
