Special Issue Information

Dear Colleagues,

Biomass in the form of cellulose is the most abundant non-fossil-based carbon source on the surface of planet Earth. Catalytic methods to convert cellulose to bulk and fine chemicals and materials offers a smart route for the replacement of fossil-based resources, and this has been the key objective of this Special Issue. The US department of energy has proposed the following chemicals, namely, 1, 4 diacids (succinic, fumaric and malic), aspartic acid, glutamic acid, 2-5 furan dicarboxylic acid, 3-hydroxy propionic acid, glucaric acid, itaconic acid, levulinic acid, 3-hydroxy butyrolactone, glycerol, sorbitol and xylitol/arabinitol as top 12 value added chemicals that serve as economic drivers for the upcoming biorefinery. The key aspect of the afore mentioned chemicals is the presence of oxygen functionality that facilitates their easy product diversification and it is more so in levulinic acid, a key platform chemical. Multifunctionality, namely, the presence of carbonyl and carboxylic acid groups in the structure of levulinic acid (CH₃COCH₂CH₂COOH, C₅H₈O₃), makes it highly reactive, with easy product diversification, via oxidation, hydrogenation, esterification, amination, dehydration followed by hydrodeoxygenation, condensation, and polymerization resulting in the formation of value added fine and bulk chemicals and biodegradable polymers. The global market size of levulinic acid is USD 20.3 million and is expected to reach USD 30.21 million by 2028. A Web of Science search with the keyword “levulinic acid” shows 8097 results as on 24th February 2022, which shows that the research in this vital field of biofuels, biochemical and biomaterials is indeed at its incipient stages and an explosive outburst and ground breaking inventions are expected in the catalytic conversion of biomass to levulinic acid and its subsequent product diversification to strategically significant fuels like C7-C10 hydrocarbons and unconventional aviation fuels like γ-valerolactone and other prominent class of fuels by name valeric fuels. Levulinic acid is designated by food and drug administration (FDA) as a generally recognized as safe (GRAS) material useful in food and drug industries as well, which is one of the reasons for the expected explosive growth in this field of research. Owing to these reasons, the objective of launching the current Special Issue titled “Production of fine and bulk chemicals and biomaterials from levulinic acid” is to make the existing and new knowledge in this field freely and widely accessible to industrial personnel and policy makers facilitating the development of biorefinery facility leading to the growth of economy, clean environment and increased job opportunities apart from meeting the global energy, chemical and material needs. The research fraternity working on “levulinic acid” is encouraged to enthusiastically contribute their results for publication in the Special Issue of the journal “Catalysts”.

Abstract

Aerobic oxidation of bio-sourced 2,5-bis(hydroxymethyl)furan (BHMF) to 2, 5-furandicarboxylic acid (FDCA), a renewable and green alternative to petroleum-derived terephthalic acid (TPA), is of great significance in green chemicals production. Herein, hierarchical porous bowl-like nitrogen-rich (nitrated) carbon-supported bimetallic Au-Pd nanocatalysts (Au_mPd_n/ N-BN_xC) with different nitrogen content and bimetal nanoparticle sizes were developed and employed for the highly efficient aerobic oxidation of BHMF to FDCA in sodium carbonate aqueous solution. The reaction pathway for catalytic oxidation of BHMF went through the steps of BHMF→HMF→HMFCA→FFCA→FDCA. Kinetics studies showed that the activation energies of BHMF, HMF, HMFCA, and FFCA were 58.1 kJ·moL⁻¹, 39.1 kJ·moL⁻¹, 129.2 kJ·moL⁻¹, and 56.3 kJ·moL⁻¹, respectively, indicating that the oxidation of intermediate HMFCA to FFCA was the rate-determining step. ESR tests proved that the active species was a superoxide radical. Owing to the synergy between the nitrogen-rich carbon support and bimetallic Au-Pd nanoparticles, the Au₁Pd₁/N-BN₂C nanocatalysts exhibited BHMF conversion of 100% and FDCA yield of 95.8% under optimal reaction conditions. Furthermore, the nanocatalysts showed good stability and reusability. This work provides a versatile strategy for the design of heterogeneous catalysts for the highly efficient production of FDCA from BHMF. Full article

Abstract

The comparatively greater cost of producing biodiesel in comparison to petroleum diesel is one of the key drawbacks. Eggshells and leftover chicken fat are examples of poultry wastes that can be used to produce biodiesel at a low cost as catalysts and oil, respectively. In this study, eggshell-derived CaO and its doping with sodium methoxide catalyst for enhancing catalytic activity was synthesized for the transesterification of waste chicken fat and characterized by FT-IR and XRD analyses. XRD studies confirmed the crystalline structure of the developed catalyst and doping of sodium with eggshell-derived CaO. The transesterification reaction was performed at different reaction parameters such as the catalyst loading, the methanol to oil ratio, the reaction temperature, and the reaction time. The biodiesel produced at the maximum yield was evaluated by gas chromatography mass spectrometry analysis. A maximum yield of 96% biodiesel was obtained with catalyst loading of 2 wt% of oil, as well as a methanol to oil ratio of 13:1 at 60 °C in 1 h. The output demonstrates that eggshell waste is a potentially accessible source of biomass-derived nano catalyst for the synthesis of biodiesel using chicken fat as a feedstock. Full article

Effects of Ca-Compounds on the Gases Formation Behavior during Molten Salts Thermal Treatment of Bio-Waste

Abstract

Bio-waste utilization is essential, and pyrolysis is a prominent way for its effective utilization. However, the gradual accumulation of ash compounds in the intermediate products probably affects the thermal conversion characteristics of bio-waste. In the present study, beech wood and disposable chopsticks were selected as bio-waste samples. The effects of typical ash components (Ca-compounds) on volatile formation behavior were investigated during the molten salts thermal treatment of bio-waste. Results demonstrated that about 80% mass of initial bio-waste was gasified into the volatiles at 300 °C. The introduction of Ca-compounds in the molten salts slightly decreased the total yield of gaseous products. More specifically, Ca²⁺ could improve the generation of CO₂ and suppress the generation of other gases (CO, H₂, and CH₄), and this is accompanied by a reduction in the low heating value (LHV) of the gases. The possible reason is that Ca²⁺ might act on the -OH bonds, phenyl C-C bond, methoxy bond and carboxylic acid -COOH bonds of the bio-waste to promote CO₂ release. In contrast, the introduction of CO₃²⁻ and OH- tended to relieve the inhibition effect of Ca²⁺ on the generation of H-containing gases. Meanwhile, the introduction of Ca²⁺ can promote the conversion of bio-waste into liquid products as well as increase the saturation level of liquid products. Moreover, as a vital form of carbon storage, CO₂ was found to be abundant in the pyrolysis gases from molten salts thermal treatment of bio-waste, and the concentration of CO₂ was much higher than that of direct-combustion or co-combustion with coal. It’s a promising way for bio-waste energy conversion as well as synchronized CO₂ capture by using molten salts thermal treatment, while the introduction of small amounts of Ca-compounds was found to have no significant effect on the change of CO₂ concentration.

Abstract

In this study, partial least square (PLS), a multivariable analysis, was used to simultaneously quantitatively evaluate the effects of variables related to three pretreatments (alkaline, hot water and acid) and the biomass properties of poplar, salix and corncob. The results showed that biomass type was the most important variable influencing enzymolysis reducing sugar yield (ERSY). The biomass compositions affected the ERSY more than the pretreatment conditions, among which hemicellulose and lignin played vital roles. The alkaline pretreatment had a more positive effect on the ERSY than the acid and hot water pretreatments, in which alkaline content had more influence than temperature. This work provides a deeper understanding of the material properties and the pretreatment conditions in different complex systems before enzymolysis, which might be a guidance to future study.

Abstract

Levulinic acid (LA) is one of the top twelve chemicals listed by the US Department of Energy that can be derived from biomass. It serves as a building block and platform chemical for producing a variety of chemicals, fuels and materials which are currently produced in fossil based refineries. LA is a key strategic chemical, as fuel grade chemicals and plastic substitutes can be produced by its catalytic conversion. LA derivatisation to various product streams, such as alkyl levulinates via esterification, γ-valerolactone via hydrogenation and N-substituted pyrrolidones via reductive amination and many other transformations of commercial utility are possible owing to the two oxygen functionalities, namely, carbonyl and carboxyl groups, present within the same substrate. Various biomass feedstock, such as agricultural wastes, marine macroalgae, and fresh water microalgae were successfully converted to LA in high yields. Finding a substitute to mineral acid catalysts for the conversion of biomass to LA is a challenge. The use of an ultrasound technique facilitated the production of promising nano-solid acid catalysts including Ga salt of molybophosphoric acid and Ga deposited mordenite zeolite, with optimum amounts of Lewis and Bronsted acidities needed for the conversion of glucose to LA in high yields, being 56 and 59.9 wt.% respectively. Microwave irradiation technology was successfully utilized for the accelerated production of LA (53 wt.%) from glucose in a short duration of 6 min, making use of the unique synergistic catalytic activity of ZnBr₂ and HCl.
