“…Alternatively, they must employ composite materials with more basic oxides [26,[28][29][30][31] (e.g., CaO, MgO, etc.) or nanostructured forms of ZnO [7,23,25,[32][33][34], thus imposing costly, time-consuming, and tedious preparations of catalysts (e.g., calcination, microwave irradiation, etc.). To date, no studies have been reported on the use of ZnO in its commercial bulk form, and very few reports deal with the application of zinc oxide to waste lipids and processes involving the simultaneous esterification and transesterification of highly acidic, unrefined feedstocks [23,29].…”

A new protocol for biodiesel production is proposed, based on a binary ZnO/TBAI (TBAI = tetrabutylammonium iodide) catalytic system. Zinc oxide acts as a heterogeneous, bifunctional Lewis acid/base catalyst, while TBAI plays the role of phase transfer agent. Being composed by the bulk form powders, the whole catalyst system proved to be easy to use, without requiring nano-structuration or tedious and costly preparation or pre-activation procedures. In addition, due to the amphoteric properties of ZnO, the catalyst can simultaneously promote transesterification and esterification processes, thus becoming applicable to common vegetable oils (e.g., soybean, jatropha, linseed, etc.) and animal fats (lard and fish oil), but also to waste lipids such as cooking oils (WCOs), highly acidic lipids from oil industry processing, and lipid fractions of municipal sewage sludge. Reusability of the catalyst system together with kinetic (Ea) and thermodynamic parameters of activation (ΔG‡ and ΔH‡) are also studied for transesterification reaction.

The growing concern about global warming and the consumption of fossil fuels has driven in recent decades the use of biomass as a renewable feedstock. In this context, vegetable oils, the corresponding fatty acids (FAs) and esters (FAEs) have primary importance: their esterification and transesterification lead to innovative products, that find application in several sectors, from biofuels to solvents, from surfactants to cosmetic ingredients and plasticizers. Lewis acid catalysis represents the most accredited methodology for developing processes of esterification and transesterification in line with sustainability requirements. The results available so far reveal the prevalent catalytic role of Zn(II) salts and coordination compounds, due to their beneficial eco-toxicological profile, combined with an appropriate acidity, finely tunable through selective functionalization. This review provides a picture of the state of the art in this important sector of biomass valorization. Roberto Esposito received his PhD in Chemical Sciences in 2018 at the University of Naples Federico II under the supervision of prof. F. Ruffo. He is researcher at the Department of Chemical Science of the University of Naples Federico II and his main research topics are W (VI), Zn(II) and Fe(III) based catalysts for conversion of biomasses and chemistry of tetra-coordinated and penta-coordinated complexes of Pt(II). Massimo Melchiorre graduated in Chemical Sciences in 2018. He is Board Member of ISusChem s.r.l., innovative start-up and university spin-off at the Dipartimento di Scienze Chimiche of the Università di Napoli Federico II. Company activity consists in biomass conversion and bio-based products development.

“…Practically, some support materials may contribute to catalytic activity, such as MgO and ZnO 60,200 . However, those materials usually have less or no activity compared with the active species except in nano‐sized structure and/or operated at higher critical condition 201–203 . An opposite way from catalyst supporting approach is the coating of the active catalyst with a stable and inert material such as Au 204 .…”

Biodiesel production technologies, which are non-catalytic and those involving the use of heterogeneous catalyst(s), have gained much interest owing to its high biodiesel and pure glycerol throughput. During the past 15 years, many studies were devoted to explore new catalysts as well as improve non-catalytic technologies with aims to ultimately industrialize such biodiesel production processes. This review elucidates the main process parameters that influences non-catalytic and heterogeneous-catalyzed biodiesel production processes. The common parameters among these technologies include the process temperature, alcohol/oil molar ratio, pressure, catalyst loading, and feedstock quality.Optimization of these process parameters is discussed according to the use of conventional method (one factor at a time [OFAAT]) or the use of statistical methods such as response surface methodology (RSM), artificial neural network (ANN), and Taguchi method. In addition, recent development on noncatalytic process and those involving the use of heterogeneous catalyst(s), such as glycerol-free processes under supercritical conditions of alkyl donors and strategies to improve properties of heterogeneous catalyst, are also reviewed.Finally, insight based on the published techno-economical evaluations is also tackled, and future prospects and research directions on these technologies are also discussed.
