“…A large number of value-added chemicals such as propanediols [39], acrolein [40], dihydroxyacetone [41], glyceric acid [42], hydrogen [43], synthesis gas [44], esters [45,46], etc., can be produced from glycerol using oxidation, reduction and other catalytic reactions (Scheme 1). Oxidation of primary, secondary, and all three groups yields different molecules of C 3 acids, aldehydes, and ketones [47,48].…”

Biodiesel is one of the most attractive sources of clean energy. It is produced by the transformation of vegetable oils with up to 10% formation of glycerol as a by-product. Therefore, development of new approaches for processing bio-glycerol into such value-added chemical compounds as solketals is necessary. Thus, various six- and five-membered cyclic compounds can be prepared by acetalization of glycerol with aldehyde or ketone. The resulting glycerol oxygenates are excellent fuel additives that increase viscosity, octane or cetane number, and stability to oxidation. In addition, these products significantly reduce carbon monoxide emissions from standard diesel fuel. In this review, we highlight recent advances in the glycerol valorization for the sustainable production of bio-additives. The review includes a discussion of the innovative and potential catalysts to produce solketals.

The increasing production of biodiesel has led to a glut in the production of glycerol, which is a byproduct. This has resulted in the quest for alternative applications using glycerol as a cheap and readily available starting material. One promising approach is the catalytic valorization of glycerol, which converts glycerol into valuable chemicals such as 1,2‐propanediol, lactic acid, and acrolein. The glycerol formed affects the efficiency of the biodiesel, and hence it must be removed. Different processes can convert glycerol to various useful products like glycerol carbonate, glycidol, solketal, lactic acid, and glyceric acid. These different products, the processes used for synthesis, and the various catalysts used have been discussed. The most effective methods for the syntheses, the numerous catalyst systems, mechanisms of the reactions, and applications of these products in different fields are discussed in this review. The paper also discusses the challenges and opportunities of glycerol valorization, including the need for improved catalyst selectivity and activity and the potential for integrating glycerol valorization with other biorefinery processes. Overall, the catalytic valorization of glycerol offers a promising pathway for utilizing this abundantly available resource, and this review provides valuable insights for researchers and practitioners working in this area.

“…The catalytic routes employed for glycerol oxidation vary from heterogeneous or homogeneous catalysis to biocatalysis or electrochemical oxidation [8]. Heterogeneous catalysts use a commonly supported noble metal, with limited reuse and high cost [1,2,9]. Homogeneous catalysis is mainly performed using expensive stoichiometric oxidants, such as halogenated organic solvents, and generates hazardous or toxic waste, that reduces their industrial interest [1,3,8,10,11].…”

“…Biocatalysis is an alternative route, where microorganisms and enzymes uses glycerol as a carbon substrate [8]. Special attention is given here to the enzymatic glycerol oxidation performed by the multi-copper containing laccases (EC 1.10.3.2 ρdiphenol:dioxygen oxidoreductases) in a TEMPO-mediated system [9,[12][13][14]. Laccasemediator systems (LMS) are widely used in organic synthesis typically using ABTS, syringaldazine, β-diketones, and TEMPO as mediator.…”

“…To the best of our knowledge, only alumina pellets and Na-alginate matrixes have been employed to laccases immobilization and complexes applied to glycerol TEMPOmediated oxidation [9,12,13]. This gave rise to the following questions: a) Would it be possible to take advantage of the physicochemical properties of nanozeolites to immobilize laccases?…”
