This study investigated the effect of reaction parameter, reaction kinetics and mechanism of transesterification of sunflower oil with methanol by using CaO/ZnO heterogeneous catalyst. The influence of reaction time, molar ratio and catalyst amount and reaction temperature on fatty acid methyl esters (FAME) yield was investigated. The catalysts were prepared by incipient wetness impregnation and characterized by using X-ray diffraction (XRD) and Hammett indicator method. The FAME contents were analyzed by gas chromatography using the EN 14103 standard method. The highest FAME yield of 82% was obtained at 9/1 methanol/oil molar ratio, 3 wt.% catalyst amount and 3 hours of reaction time at 65 °C of reaction temperature by using 20% CaO/ZnO catalyst. The reaction could be considered pseudo first order with respect to triglyceride (TG). The reaction model based on Eley-Rideal mechanism was proposed where adsorbed methanol reacted with TG before desorption of glycerin. The results showed that experimental reaction rates exhibited good agreement with calculated reaction rates.

“…2D Na/ITQ-2 is a two-dimensional basic zeolite contains natrium and ITQ-2 zeolite which possess large external surface areas, hierarchical characteristics, stable active sites, and a high concentration of strong basic sites that contribute to enhancing the mass transfer of bulky molecules and providing more accessible and stable active sites in the transesterification of bio-derived oil to produce biodiesel. A similar investigation conducted by Mansir et al [101] using bimetallic tungsten zirconia (W-Zr) samples to catalyze simultaneous esterification and transesterification of unrefined palm-derived waste oil (PDWO) to biodiesel. The catalyst with a 7 wt% concentration of W-Zr loaded on CaO support (7WZC) was able to achieve a maximum biodiesel yield of 94% in one-hour reaction time under the optimum reaction condition (methanol and oil molar ratio of 15:1, 2 wt% catalyst loading, 80 • C reaction temperature).…”

Biodiesel has caught the attention of many researchers because it has great potential to be a sustainable fossil fuel substitute. Biodiesel has a non-toxic and renewable nature and has been proven to emit less environmentally harmful emissions such as hydrocarbons (HC), and carbon monoxide (CO) as smoke particles during combustion. Problems related to global warming caused by greenhouse gas (GHG) emissions could also be solved by utilizing biodiesel as a daily energy source. However, the expensive cost of biodiesel production, mainly because of the cost of natural feedstock, hinders the potential of biodiesel commercialization. The selection of natural sources of biodiesel should be made with observations from economic, agricultural, and technical perspectives to obtain one feasible biodiesel with superior characteristics. This review paper presents a detailed overview of various natural sources, their physicochemical properties, the performance, emission, and combustion characteristics of biodiesel when used in a diesel engine. The recent progress in studies about natural feedstocks and manufacturing methods used in biodiesel production were evaluated in detail. Finally, the findings of the present work reveal that transesterification is currently the most superior and commonly used biodiesel production method compared to other methods available.

“…As could be seen, the conversion of oleic acid decreased after each run from 45.7% (first run) to 17.9% (sixth run) for the HPW@CoCe-MOF catalyst, and the possible reasons for the reduction substantially of conversion are the blockage of the CoCe-MOF channel. On the contrary, the conversion of oleic acid decreased slightly after each run from 67.2% (first run) to 61.8% (eighth run) for the HPW@CoCeO catalyst, and the decrease in catalytic activity could be related to the adsorption of oleic acid, methanol, or water molecule on the active sites of the HPW@CoCeO composite during each run [39]. e collected catalyst from the eighth reaction cycle was characterized by FTIR (Figure 2).…”

The impregnation of phosphotungstic acid (HPW) with porous cobalt-cerium oxide (HPW@CoCeO) has been prepared by pyrolysis of CoCe-MOF and used for the production of methyl oleate from oleic acid and methanol. FTIR, XRD, SEM, TEM, N2 adsorption/desorption, and NH3-TPD were characterized for the prepared composites. Simultaneously, the effects of reaction time, substrate molar ratio, temperature, and catalyst loading on catalytic activity were highlighted, and the conversion of 67.2% was reached after 4 h at 60°C. Importantly, HPW@CoCeO was reusabe and reused more than eight times, and the oleic acid conversion could be maintained at 61.8% without significant activity loss. Thus, the HPW@CoCeO composite could be used as acid catalysts for sustainable energy production.
