“…Chemisorption forms covalent bonds between adsorbents and adsorbates, resulting in adsorbents attached to the adsorbates. 69 Physical adsorption through physical action, such as the dispersion force, dipole interaction, quadrupole interaction, electrostatic force, hydrogen bond, and other forces, results in the substance being attached to the adsorbent. Adsorption method has the advantages of saving energy, protecting the environment, and having a high efficiency and a low cost, as well as being easy to operate, so it has been widely used in the chemical, petroleum, food, and light industries and in environmental protection and other fields.…”

Levulinic acid (LA), a class of important chemical intermediates and new energy chemicals, has been considered one of the top-12 platform compounds that can be converted from biomass resources. Substantial progress on the conversion of lignocellulose biomass to LA and the further conversion of LA to high value downstream chemicals have been achieved recently. This review summarizes the preparation and separation processes of LA firstly, and then, emphatically discusses the catalytic system for LA conversion to valuable downstream products, including levulinate esters, 2-methyl tetrahydrofuran (MTHF), Gammavalerolactone (GVL), 5-aminolevulinic acid (DALA), and diphenolic acid (DPA). An outlook is provided at the end of this paper to highlight the challenges and opportunities for the comprehensive utilization of lignocellulose biomass.

BACKGROUND: Levulinic acid is one of the top ten bio-derived platform chemicals essential for producing many products that are used daily. The recovery of biobased chemicals from industrial streams and fermentation broths is critical due to environmental issues. A few studies have used chemical solvents for the recovery of levulinic acid, but these solvents are toxic for microorganisms. Therefore, green and cheap solvents for the separation of levulinic acid are needed. This study used sunflower oil as a green solvent with trioctylamine and tri-n-butyl phosphate for the separation of levulinic acid. The experimental study was presented in the form of important parameters, viz., distribution constant, loading ratio, extraction equilibrium constant, diffusion coefficient, and extraction efficiency. Fourier transform infrared spectroscopy (FTIR) was employed to understand the acid and extractant interactions and 1:1 complex formation was confirmed in organic phase. RESULTS:The experimental results include the distribution coefficients (0.14-0.81 and 0.23-2.15), loading ratios (0.013-0.709 and 0.023-0.53), extraction efficiencies (12.43-44.68% and 19-68.30%), and extraction equilibrium constants (0.47-1.63) with trioctylamine and tri-n-butyl phosphate, respectively. Since a single-stage does not provide sufficient extraction efficiency, multi-stage extraction was performed. The multistage design shows that trioctylamine and tri-n-butyl phosphate must be used in three and five stages, respectively, to get 94.8% and 97% recovery of levulinic acid.CONCLUSION: This study describes the recovery of levulinic acid from the aqueous phase using trioctylamine and tri-n-butyl phosphate with sunflower oil as a sustainable green solvent. The multistage design setup provided approximately 100% recovery of levulinic acid.

Many industries are using directly biomass as a raw material for the production of valuable biochemicals. These are used different toxic chemicals such as sulphuric acid, hydrochloric acid, nitric acid, etc. as a catalyst during the production of biochemicals and exit downstream waste material and create environmental pollution. Therefore, downstream waste material separation is important for decrease environmental pollution. Levulinic acid is a carboxylic acid which can be present downstream of industrial waste. It is a very important chemical and can be transformed into different important chemicals such as 1-4 pentanediol, aminolevulinic acid, succinic acid, gamma valarolactone, hydoxyvaleric acid, diphenolic acid, etc. It is considered in the top ten important and bio-derived acids. Levulinic acid can be directly produced from biomass through chemical synthesis and fermentation processes at industrial and lab scales. The synthesis process produces the char whereas the fermentation process produces wastes during the production of levulinic acid, thus increasing the production cost and industrial waste downstream. The separation of levulinic acid from the waste is costly and challenging. In this study, reactive extraction was employed with TOA in i-octanol for the separation of levulinic acid. The experimental results have been expressed in various performance parameters like distribution coefficient (0.099-6.14), extraction efficiency (9-86%), loading ratio (0.09-0.7), and equilibrium constant (11.34-1.05). The mass action law model was also been applied and found the predicted value close with the experimental results. The mixer settler extraction in the series was used to achieve more than 98% separations of acid. Further, the conceptual approach for levulinic acid separation using mixer-settler reactor scheme is discussed and presented various design parameters including extraction efficiency, diffusion coefficient, extraction equilibrium constant, and loading ratio. This study decreases the industry downstream material and can be solved environmental pollution problems.
