    This study is focused on the development of a heterogeneous Fe-Co bimetallic nanoparticle on Pindiga bentonite clay support to be used in the production of biodiesel. The local clay was beneficiated and used in the preparation of catalyst by wet impregnation method. The X-ray Fluorescence analysis (XRF) of the bentonite clay showed the presence of several metals and metallic oxides with good catalytic effect. Characterization of the prepared catalyst using Fourier Transform Infared Ray (FTIR), Energy Dispersive Spectrometer, (EDS) X-Ray Dispersion (XRD) and Scanning Electron Microscopy (SEM) confirmed the functional groups, elemental compositions, crystallinity, and morphology of the catalyst respectively. The catalyst was evaluated in biodiesel production using Box-Behnken optimization by varying the methanol: oil mole ratio, reaction temperature, reaction time, and catalyst concentration. An optimum yield of biodiesel (93.8 %) was obtained at process condition of 15:1 methanol: oil mole ratio, 55 °C reaction temperature, 1 h, reaction time, and 15 % (w/w) catalyst concentration. Physicochemical properties of the biodiesel produced using the developed Fe-Co/ bentonite nanocatalyst showed that the biodiesel is of good quality. This was further confirmed by the FAMEs profile. Therefore, the Fe-Co/bentonite nanocatalyst showed potential application as heterogeneous nanocatalyst for the trans-esterification of vegetable oil to biodiesel, an alternative and sustainable replacement for conventional petroleum diesel.

    HETEROGENEOUS CATALYSIS USING BENTONITE-SUPPORTED Fe-Co-Ni TRIMETALLIC NANOPARTICLES
    (Alma Mater Publishing House "Vasile Alecsandri" University of Bacau, 2021) Aderibigbe, Fatai Alade; Adewoye, Tunmise Latifat; Mustapha, Sherif Ishola; Muhammed, Alhassan Ishaq; Saka, Harvis Bamidele; Ajala, Elijah Olawale; Oluwaseyi, Soile Samuel
    Abstract: Herein, the synthesis and characterization of a bentonite-supported Fe-Co-Ni trimetallic nanocatalyst applied in transesterification reaction was reported. The synthesized heterogeneous catalyst was used to investigate the production of biodiesel by varying the reaction parameters using Box-Behnken design response surface methodology (RSM-BBD). An optimum biodiesel yield of 95.2 % was obtained at methanol to oil ratio of 10:1, reaction time of 2 hours, reaction temperature of 55 ℃ and catalyst concentration of 5 % (w/w of the oil). The biodiesel produced was later analysed using GC-MS analysis and the results shows a fatty acid methyl esters (FAME) profile that confirms the presence of biodiesel.
