“…The experimental conditions currently applied were clearly softer than those required for the production of conventional biodiesel with supported KF catalysts [29][30][31][32][33][34][35][36]. These results are also similar to those obtained with CaO [27] in regard to the values of conversion and selectivity parameters; however are better respect to the kinematic viscosity values obtained.…”

“…The catalysts KF/ZnO and KF/MgO let a second reuse, with the same catalytic behavior that in the first one, and a softer decline in Conversion and Performance that in the Al 2 O 3 catalyst. However, the CaO catalyst [27] showed a better performance in regard to the reuse of the heterogeneous catalysts.…”

“…By difference and respect to the internal standard (cetane), the amount of triglycerides (TG) which has not reacted, is calculated. The Conversion includes the total amount of triglyceride transformed (FAME + MG + DG) in the methanolysis process and Selectivity makes reference to the relative amount of FAME + MG obtained, which exhibit retention times (RT < 25) similar to conventional diesel fuel [20,21,27].…”

“…To determine the comparative behaviour of the different supported KF systems, in Table 1 are collected the results obtained when operating under the standard conditions previously determined with CaO heterogeneous catalysts [27]. Thus, reactions were carried out with 0.8 g of 10 wt% supported KF on the three inorganic solids, Al 2 O 3 , ZnO and MgO, at 65 ºC reaction temperature with 12 mL of sunflower oil (32 cSt, kinematic viscosity) and 2.43 mL of methanol.…”

“…1). In this respect, some promising results have been previously obtained by using CaO as an alkaline heterogeneous catalyst [27]. In the present research, a series of KF supported catalysts, previously applied as basic catalyst in some organic synthetic process [28], are investigated in the methanolysis reaction of sunflower oil to obtain the selective transesterification, through the kinetic control of the consecutive chemical process, to get the same biodiesel without glycerol generation, as an alternative to the more expensive lipases.…”

This study describes the results obtained in the synthesis of a biofuel that avoids the glycerol production by applying supported KF as alkaline heterogeneous catalyst, to generate two moles of fatty acid methyl esters and one mole of monoglyceride, from one mol of triglyceride. In this respect, the selective transesterification process of sunflower oil with methanol was carried out with KF10 wt % supported on three different solids, Al 2 O 3 , ZnO and MgO. The standard experimental conditions employed in the heterogeneous selective methanolysis reaction were: 12 mL of sunflower oil, 2.7 mL of methanol, 0.8 g of catalyst, at 65 °C temperature and one hour of reaction time. In all cases were obtained 100% conversion, with high selectivity values, greater than 90%, and quite suitable viscosity values, 4.5-8.5 cSt. In this way, the best catalytic behavior in the first use was obtained by using Al 2 O 3 as support. However, although in the five consecutive reuses all exhibited a continuous decrease in the catalytic activities; the lower one was for KF catalyst using MgO as support. In summary, these three KF supported catalysts have OPEN ACCESSEnergies 2013, 6 2 resulted to be very suitable to obtain a new biofuel, similar to conventional biodiesel, applicable to diesel engines.

In a world where fossil fuels are running out, biofuels are one of the best green energy alternatives to fuels made from petroleum due to their environmentally beneficial qualities and low cost in comparison with non-renewable fossil fuels. Biofuels are produced from cheap and renewable sources and the energy stored in these biomasses can be assimilated to create sustainable electricity or heat, which can then be exploited to meet current and future societal needs in numerous situations. However, the production of biofuels on an industrial scale takes a lot of time because of the numerous constraints placed on currently available technology and the increased costs that go along with them. Moreover, the processes utilized to transform various feedstocks into the desired output also vary based on the materials and techniques employed. The supply of biofuel feedstocks is large, and with improved processing, we could significantly lower our reliance on fossil fuels. In this context, the use of nanoparticles (NPs) is a commendable solution to the present problems with biomass use, especially given their low cost. The unique qualities of nanomaterials, such as excellent catalytic properties, high surface area-to-volume ratio, remarkable selectivity, and reusability make them admirable tools for boosting biofuel generation. This review predominantly focuses on the contributions of nanotechnology and various immobilization methodologies in accelerating biofuel production from biomasses that might fill in the research gap, which was previously limited by the relatively lower efficiency of traditional techniques of biofuel generation.

Heterogeneous Catalysis of Second Generation Oil for Biodiesel Production: A Review

The demand for cleaner fuels has been on the rise lately, prompting researchers to explore alternative cleaner technologies to meet the growing demand. This has led to the introduction of renewable fuels such as bioethanol and biodiesel. Depending on the feedstock employed for production, renewable fuels can be divided into first, second, and third generation. Reliance on first generation biofuel feedstocks has led to inherent competition between foods versus fuels in the society in the last decade. Further technological prospects in research and development have provided insight into the use of second generation biofuel feed‐stocks from non‐edible agricultural waste products, energy crops, and crop residues. Zeolites and modified zeolites as heterogeneous catalysts have been highly prospective for the transesterification process of these oils. Modified zeolite can act as a bi‐functional catalyst because of its acidic and basic sites. Here, a review of transesterification reaction technology, zeolite and modified zeolite as a heterogeneous catalyst to generate biodiesel was discussed. Current status, challenges and future prospects are also discussed.
