“…They impregnated different metal oxides on eggshell and produced biodiesel (~ 94.5%) at optimum conditions: 7 wt% catalyst weight, 12:1 methanol to molar ratio, and 180 min. Foroutan et al 12 used rice husk ash (RHA)/ CuO/K 2 CO 3 as a catalyst for biodiesel production. They achieved maximum biodiesel yield 98.1% under optimum condition 3 wt% catalyst, reaction temperature of 65 °C, and 120 min.…”

Burning fossil fuels causes toxic gas emissions to increase, therefore, scientists are trying to find alternative green fuels. One of the important alternative fuels is biodiesel. However, using eco-friendly primary materials is a main factor. Sustainable catalysts should have high performance, good activity, easy separation from reaction cells, and regenerability. In this study, to solve the mentioned problem NaOH@Graphene oxide-Fe3O4 as a magnetic catalyst was used for the first time to generate biodiesel from waste cooking oil. The crystal structure, functional groups, surface area and morphology of catalyst were studied by XRD, FTIR, BET, and FESEM techniques. The response surface methodology based central composite design (RSM-CCD) was used for biodiesel production via ultrasonic technique. The maximum biodiesel yield was 95.88% in the following operation: 10.52:1 molar ratio of methanol to oil, a catalyst weight of 3.76 wt%, a voltage of 49.58 kHz, and a time of 33.29 min. The physiochemical characterization of biodiesel was based to ASTM standard. The magnetic catalyst was high standstill to free fatty acid due to the five cycle’s regeneration. The kinetic study results possess good agreement with first-order kinetics as well as the activation energy and Arrhenius constant are 49.2 kJ/min and 16.47 * 1010 min−1, respectively.

“…Biodiesel can be produced from vegetable oil i.e. palm oil, jatropha and microalgae (Rajpoot et al, 2023), sunflower and castor oil (Foroutan et al, 2023), soybean oil (Sarkar et al, 2023;Yusuf et al, 2023), coconut oil (Mendez et al, 2022) and from waste cooking oil (Astuti el al., 2023a). The transesterification process of vegetable oil is a slow reaction, so it requires a catalyst to reduce the activation energy and speed up the reaction rate.…”

Renewable energy in the form of biodiesel requires a process called transesterification. This process runs slowly, so a catalyst is needed to reduce the activation energy and speed up the reaction rate. Activated carbon is one of the supports in transesterification catalysts because of its high surface area and is proven to be effective in gas or liquid phase reactions. This work aims to study the potential of active carbon from tamarind wood for making catalysts, the characteristics of the catalyst and the optimal concentration of Fe(NO3)3 in the impregnation step. Activated carbon was impregnated using an Ultrasonic Processor with 80% strength at 60 oC for 60 minutes. The impregnation process was carried out with variations of 2, 4, and 6% Fe(NO3)3 dissolved in 0.09M isopropyl alcohol. Variation of processing time 30, 40, 50, 60, 70, 80 minutes. Furthermore, after the activated carbon is allowed to stand for 24 hours, a calcination process is carried out at 300oC to remove impurities. Obtained materials have been characterized by SEM and XRD. The Fe-impregnation process has been successfully carried out on activated carbon made from Tamarind wood (Tamarindus indica L.). In the Fe precursor solution concentration range of 2 – 6%, the higher the concentration of the Fe precursor solution, the higher the impregnated Fe metal. Fe-impregnated activated carbon has the characteristics of being a material consisting of a mixture of crystalline and amorphous phases with even porous surface morphology. This Fe-impregnated activated carbon is a potential material as a catalyst in the biodiesel production process.
