“…In the case of copper catalysts with a higher copper content in the system (10 wt.% of Cu), the catalytic activity tests conducted in the tested reaction confirmed higher triglyceride conversion values and higher yields of methyl esters compared to their analogues containing 5 wt.% of copper. Chang et al [33] investigated a copper-based supramolecular catalyst on β-cyclodextrins (β-CD) in the transesterification reaction of Xanthium sibiricum Patr oil. The Cu-β-CD catalyst was evaluated in a reaction carried out in a glass three-necked flask with a condensing means placed in an oil bath.…”

This work focuses on the study of biodiesel production from commercial rapeseed oil and methanol via transesterification reactions on monometallic copper and bimetallic copper–noble metal (platinum, ruthenium) catalysts supported on BEA zeolite. The catalysts were prepared by wet impregnation method on the hydrogen form of BEA zeolite. As part of the study, the physicochemical and catalytic properties of the prepared catalytic materials were determined. The catalytic activity tests were carried out in the transesterification reaction over prepared catalysts at 220 °C for 2 h in an autoclave. The physicochemical properties of the obtained catalysts were investigated by X-ray diffraction (XRD), specific surface area and porosity (BET), a scanning electron microscope equipped with an energy dispersive spectrometer (SEM–EDS) and temperature-programmed desorption of ammonia (TPD-NH3) method. The results of the catalytic activity showed the promotional effect of the noble metal on the TG conversion and FAME efficiency of copper catalysts in the biodiesel production process. The most active catalyst turned out to be the calcined 5%Cu–1%Ru/BEA catalyst, which showed the highest TG conversion of 85.7% and the second highest FAME efficiency of 58.4%. The high activity of this system is explained by its surface acidity and large specific surface area.

“…The incorporation of copper to the DS-HMS-NH 2 surface also increases the thermal stability of the catalyst and improves the esterification efficiency in converting the FFA to fatty acid methyl ester (FAME). 8,21 Therefore, it is certainly of great interest to study the catalytic performance of Cu/DS-HMS-NH 2 , as this bifunctional catalyst improves the chance of low-quality oil to be widely utilized as the raw material for biodiesel production, and at the same time, offers an ability to promote the concurrent esterification/ transesterification reaction in a one-pot synthesis.…”

Double‐shelled hollow mesoporous silica incorporated copper (II) (Cu/ DS‐HMS‐NH ₂ ) as a catalyst to promote in‐situ esterification/transesterification of low‐quality palm oil

et al. 2021

To encourage the utilization of low-quality palm oil with high free fatty acid and moisture content (>0.1 wt%), a novel catalyst with two spatial shells and different active sites, double-shelled hollow mesoporous silica incorporated copper (II) (Cu/DS-HMS-NH 2 ), is fabricated via the two-stage hydrolysis and condensation technique. The influence of four parameters (eg, catalyst loading, temperature, reaction time, and the mass ratio of methanol to degummed palm oil (DPO)) on the yield of fatty acid methyl ester (FAME) are monitored and optimized using a combination of response surface methodology (RSM)and face centered-central composite experimental design (CCF-CCD). The optimized FAME yield is predicted at 86.63 wt% and experimentally obtained at 87.14 ± 0.11 wt% (FAME purity of 98.45 ± 0.67 wt%) under the following optimum condition: 55.3 C, 5 h, methanol to DPO mass ratio of 5.3:1, and 5 wt% catalyst loading. The experimental and predicted values are proportional and in direct agreement with an error of 0.51%. The goodness of fit analysis also indicates conformity between the mathematical model and the experimental results. The reusability study shows that Cu/DS-HMS-NH 2 is stable until the fifth run, evident from the yield of FAME which stays above 80%. These results prove the potential utility of Cu/DS-HMS-NH 2 for the direct conversion of low-quality vegetable oils to biodiesel without any pre-treatment.

Advances in Metal Oxide‐based Nanocatalysts for Biodiesel Production: A Review

et al. 2023

The demand for renewable fuels has risen as a result of increasing human population, urbanization, industrialization, and transport systems. Biodiesel production using metal oxide-based heterogeneous catalysts is an efficient, sustainable, and environmentally friendly approach. Because of their recovery, reusability, and consistency, heterogeneous catalysts may be preferable to homogeneous catalysts. Since the last few decades, the metal oxides of alkali earth and transition metals and their composite materials have been used as nanocatalysts in the production of biodiesel fuel. Utilization of inorganic metal oxide nanoparticles (MONPs) and their composite materials in producing biodiesel has gained increased attention because of their advanced physical and chemical characteristics. In this review, the applicability of metal oxides and their nanocomposite-based catalysts in biodiesel production, transesterification reactions with nanocatalytic systems, and the important parameters that affect these reactions are discussed.
