“…C20 : 2, and C20 : 3). Biodiesel production from rape oil under SCE using Al 2 O 3 , ZnO/Al 2 O 3 , MgO/Al 2 O 3 , and SrO/ Al 2 O 3 as a heterogeneous catalyst was studied by Mazanov et al [105] At high temperature of 380 °C, 30 MPa, and a 12 : 1 ethanol to oil molar ratio, the highest FAEE of 97.46 was achieved using 2 wt % SrO/Al 2 O 3 as the optimal catalyst. Since 5 wt % ZnO/Al 2 O 3 has almost the same FAEE content compared to 2 wt % SrO/Al 2 O 3 , a cost estimation study may give more practical results for its use in commercial applications.…”

Nowadays, due to detrimental carbon dioxide emissions and dwindling non‐renewable fossil energy from crude oil, biodiesel from green sources such as vegetable oils, animal fats, waste oils and microbial oils have been described as a promising non‐fossil fuel, renewable, sustainable, clean, and biodegradable. So far, transesterification is the most superior process for converting green resources into biodiesel by reacting with alcohol in the presence of a catalyst. This process is influenced by some considerations such as alcohol to oil molar ratio, reaction temperature, reaction pressure, reaction time and specifically the amount of catalyst, which greatly affect the reaction performance and the biodiesel production. In depth, this review will discuss novel catalysts for biodiesel production under supercritical methanol and ethanol conditions by reviewing published articles related to this field to date.

The strontium‐manganese supported over ceramic was synthesized through wet impregnation method and investigated as a solid catalyst for its catalytic performance in transesterifying‐esterifying low‐grade waste frying oil with methanol in a batch reactor; parameters for synthesis of catalyst and transesterification reaction were also optimized. The maximum biodiesel yield of 93.66 % was attained by SrO‐MnO/Ceramic catalyst under normal process conditions. The synthesized catalyst reusability potential was also evaluated for 12 runs with regeneration carried out after the 7th run only and it revealed that the catalyst showed great stability for the initial five cycles offering yield of over 90 %. The fresh and used SrO‐MnO/Ceramic catalysts were characterized to address the mechanism of catalytic behavior and deactivation using scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDS), X‐ray diffraction (XRD), benzoic acid and n‐butylamine titration method, and Hammett indicators. The alteration in surface morphology; Mn solubility in glycerol and methanol; occupation of energetic centers by organics might be the reasons for diminished activity or deactivation of solid catalyst after repeated reuse.
