    (LAUTECH Journal of Engineering and Technology, 2020) Aderibigbe, Fatai Alade; Adewoye, Tunmise Lateefat; Mustapha, Sherif Ishola; Muhammed, Alhassan Ishaq; Amosa, Mutiu Kolade; Saka, Harvis Bamidele; Mohammed-Nuhu R.A.; Adejumo, Ayoade Lateef; Owolabi, Rasheed Uthman
    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.

    Current Trends and New Perspectives in Biodiesel Production: A Focused Review on Interesterification Reaction
    (Proceedings of the Annual Conference of Nigerian Society of Chemical Engineering Held at Eko Hotel, 2021) Aderibigbe, Fatai Alade; Bello, Bisola Taibat; Adebayo, Rashidat O.; Olufowora, Fatimah O; Saka, Harvis Bamidele; Amosa, Mutiu Kolade; Karimu, Olatokunbo S.
    The consumption of energy has risen to 12 billion tons/year due to the ever-increasing population and urbanization which has directly led to more energy demand. Hence, there is an obvious need for an alternative source of fuel energy. One of the best alternatives is the use of renewable fuel energy. Biodiesel is an example of a renewable fuel energy which is produced from biomass by different technologies such as direct blending of oil, emulsification, pyrolysis, and transesterification. However, the drawback of these methods has propelled research experts to persistently search for better technologies. Over the years, transesterification reaction methods have been globally identified for in biodiesel production. Nonetheless, its by-product named glycerol has limited its utilization in biodiesel production. Therefore, it has been reported that the integration of glycerol into biodiesel composition may be a better option. In this review, the latest biodiesel production technology discussed is the interesterification reaction. This method integrates the by-product (glycerol) by producing a glycerol free Fatty Acid Methyl Esters (FAME), triacetin which is a useful fuel additive is produced instead. After the production of biodiesel and triacetin through the interesterification reaction route, there is always no need to separate both products which makes this process interestingly more sustainable and economical. The current trends of this production technology are also expounded.

    Kinetic Study of the Transesterification of Waste Cooking Oil
    (Department of Mechanical Engineering, Gen. Abdusalami Abubakar College of Engineering, Igbinedion University, Okada, Edo State, Nigeria, 2022) Aderibigbe, Fatai Alade; Saka, Harvis Bamidele; Mustapha, Ishola Sherif; Mohammed, Alhassan Ishaq; Amosa, Mutiu Kolade; Adeniyi, Adewale George; Ajala, Elijah Olawale; Babatunde, Esther Olubunmi; Solomon, Bamidele Ogbe
    The rate and cost of biodiesel production has been hampered by the nature of the catalysts and feedstocks used. The bifunctional catalyst prepared from the mixture of 40 wt% sulphonated corncob (acid source) and 60 wt. % calcined cowbone (base source) was employed in the kinetic studies of the waste cooking oil transesterification for biodiesel production. The kinetic reaction tends towards fitting into a pseudo-first order reaction with activation energy (Ea) and collision factor of 21.4833 kJ/mol and 0.4909𝑠−1 , respectively. The effects of each parameter on the production of biodiesel were highlighted. The physicochemical properties such as the flashpoint (403 K), pour point (281.2 K) and cloud point (283.11 K) of the synthesized biodiesel were also obtained. Furthermore, a test on reusability was performed for the bifunctional catalyst and it was found to retain its catalytic potential until the fifth cycle with a percentage catalyst loss of 7 %. This result indicates that the bifunctional catalyst was effective in the kinetic study of the transesterification of waste cooking oil.
