“…Firstly, all carbon that is transferred to side products is a waste of feedstock, and must be removed cost-intensively from HMF. Secondly, high-molecular-weight condensation products are poorly soluble in water, and can cause the plugging of pipes and apparatuses [6]. …”

“…HMF has been named as one of the top ten value-added bio-based chemicals by the U.S. Department of Energy [5]. It can be produced exclusively by thermochemical conversion routes, and is highly carbon-efficient during its synthesis [6]. In principle, HMF is available from all hexoses and their polymers.…”

“…Unfortunately, HMF rehydrates in a water-based medium under acidic conditions to form the consecutive products levulinic acid and formic acid. Furthermore, the self-condensation of HMF and condensation with other compounds lead to the formation of high-molecular-weight polymeric substances (humins) [6]. The maximum yields of HMF in water are reported to be around 50-60 mol% when fructose is used as the feedstock [3].…”

“…Cellulose consists of glucose building blocks, and hemicelluloses can also contain glucose [13]. A previous isomerization of glucose to fructose is a strategy to overcome low yields from the direct conversion of lignocellulose-derived glucose to HMF [6]. By using isomerase enzymes, the fructose yield can reach the thermodynamic equilibrium (about 50 wt % [14]).…”

Hydroxymethylfurfural (HMF) has an outstanding position among bio-based platform chemicals, because high-value polymer precursors and fuel additives can be derived from HMF. Unfortunately, the large-scale industrial production of HMF is not yet realized. An open research question is the choice of hexose feedstock material. In this study, we used the highly available disaccharide sucrose for HMF synthesis. The conversion of sucrose was catalyzed by sulfuric acid in water media. Experiments were conducted at temperatures of 180, 200, and 220 • C with reaction times of 2-24 min. A carbon balance showed that the yield of unwanted side products rose strongly with temperature. We also developed a kinetic model for the conversion of sucrose, involving nine first-order reactions, to uncover the kinetics of the main reaction pathways. Within this model, HMF is produced exclusively via the dehydration of fructose. Glucose isomerizes slowly to fructose. Side products arise simultaneously from glucose, fructose, and HMF. A pathway from hexoses to xylose via reverse aldol reaction was also included in the model. We believe that sucrose is the ideal feedstock for large-scale production of HMF because it is more abundant than fructose, and easier to process than sugars obtained from lignocellulosic biomass.

Polyethylene furanoate (PEF) is a biobased plastic, similar to synthetic polyethylene terephthalate (PET), which is produced from the platform chemical 2,5‐hydroxymethylfurfural (HMF). Much of the literature surrounding PEF is focused on unit processes, with little regard for their sustainability and economic viability. In this comprehensive critical review, the entire process of PEF production, from the feedstock to polymerization and upstream applications, is critically examined. Identification of individual pathways capable of producing PEF efficiently and with favorable properties while considering economic viability and environmental sustainability are presented. For each unit operation, recent technological developments are summarized, and recommendations are made based on process efficiency. The collection of the findings from both life cycle assessments (LCA) and techno‐economic analyses (TEA) facilitated the identification of pathways with the greatest potential for environmental sustainability and economic viability of PEF production.

Rapid industrialization, increasing fuel prices, exhausting fossil fuel resources and greenhouse gas emissions are some of the factors instilling the search for alternative sources of energy and chemicals. Lignocellulose biomass-derived biofuels and biochemicals have emerged as clean products to complement fossil-based resources and reduce environmental impacts. Lignocellulosic biomasses are renewable, inexpensive and abundantly available resources to produce a wide variety of liquid, gaseous and solid biofuels and industrially relevant biochemicals. Different biological (e.g., fermentation and anaerobic digestion), thermochemical (e.g., liquefaction, gasification and pyrolysis) and catalytic (e.g., transesterification) conversion technologies can be used to produce fuel and chemical products from lignocellulosic biomass. This article makes a comprehensive review of different biofuels (e.g., biodiesel, bio-oil, bioethanol, biobutanol, biogas, hydrogen, syngas and jetfuel) and value-added biochemicals (e.g., propylene, ethylene, benzene, 5-hydroxymethylfurfural, levulinic acid, succinic acid, maleic acid, fumaric acid, phenols and other aromatic compounds) from lignocellulosic biomass. Additionally, the current status, challenges and future perspectives for the production and utilization of biofuels and biochemicals are systematically discussed.
