“…The most promising way to get fuel fungible with fossil fuels is to use natural vegetable oils and animal fats to produce fuel. There are generally two technical routes for this purpose: (1) Transesterification/esterification reaction can be applied in converting renewable feeds (vegetable oils and animal fats) into fatty acid methyl esters (FAMEs) used as biodiesel [4,5]. However, FAMEs do not change the relative oxygen content and still has high oxygen content compared to petroleum-derived fuels, which lead to the relatively poor calorific value, the low stability and high viscosity [6]; (2) the removal of oxygen from vegetable oils and animal fats is the most promising technology to obtain high-grade fuel, which provides a drop-in replacement for fossil fuel [7][8][9].…”

“…Therefore, several studies have been conducted on sulfated zirconia (SZ) for the production of biodiesel [6][7][8]. However, SZ is easily deactivated by losing sulfur groups [9,10]. Although some researchers have reported that supporting SZ by transition metals can substantially enhance the performance of the catalyst, serious concerns still remain about its long-term stability and/or regenerability [11,12].…”

The zirconia-alumina nanocatalyst was prepared using microwave combustion method, and the effects of alumina/zirconia ratio, fuel-to-oxidizer ratio, and calcination temperature on its structural and chemical performance were examined. Furthermore, the most suitable synthesized nanocatalyst was impregnated using different dosages of sulfate group to improve the activity of the sample for the esterification reaction. The results revealed that there was a significant improvement in the crystalline structure of alumina and zirconia for the samples having the alumina/zirconia ratio of 2. It was also noted that some amorphous structures were observed for low fuel dosages, while the activity of the sample was reduced with higher fuel consumption than the stoichiometric ratio, which can be attributed to the increase in the crystallite size and formation of different alumina phases. Based on calcination results, non-considerable changes were observed in the morphology and activity of the catalyst. It can be concluded that the solution combustion method is suitable for nanocatalyst preparation without any requirement of further thermal treatment. In addition, the activity of the sample was enhanced by impregnation with H 2 SO 4 where the conversion of 91.6% was achieved. The catalyst showed high reusability at least for seven times as well as high stability of zirconia-alumina as a support.

“…Biodiesel, which is also called fatty acid alkyl ester, is mainly obtained from vegetable oils and animal fats by either transesterification of triglycerides or esterification of fatty acids with alcohols such as methanol or ethanol in the presence of an alkali or acid catalyst. Nevertheless, high production cost is an impediment for commercial production of biodiesel .…”

The influence of reaction parameters like molar ratio of methanol to oleic acid, catalyst amount, and reaction temperatures for oleic acid esterification with methanol by using Zr(SO4)2 as a heterogeneous catalyst was investigated. Nearly complete conversion was obtained when the esterification reaction was carried out under optimized reaction conditions in terms of molar ratio of methanol to oleic acid, catalyst amount, reflux temperature of methanol, and reaction time. Furthermore, the kinetics of the esterification reaction was also investigated. The experimental data supported the validity of the suggested Eley‐Rideal model.
