Item BIODIESEL PRODUCTION FROM PALM KERNEL OIL USING BENTONITE CLAY-SUPPORTED FE-CO NANOCATALYST(2020-11-21) Aderibigbe, Fatai A.; Adewoye, Tunmise L.; Mustapha, Sherif I.; Mohammed, Ishaq A.; Amosa, Mutiu K.; Saka, Harvis B.; Muhammed-Nuhu, Rafiat A.; Adejumo, Ayoade L.; Owolabi, Rasheed U.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.Item PHENOL removal in refinery wastewater using mixed oxides prepared by green synthesis(2021-01-17) Aderibigbe, Fatai A.; Adewoye, Tunmise L.; Mustapha, Sherif I.; Mohammed, Ishaq A.; Saka, Harvis B.; Amosa, Mutiu K.; Adejumo, Ayoade L.; Owolabi, Rasheed U.; James, Shalom B.Mixed solid oxides are known for their excellent catalytic property and applications in environmental remediation. This study presents a green-synthesis route for magnesium oxide–titanium oxide, a mixed oxide here demonstrated to possess high performance of phenol removal from hydrocarbon refinery process wastewater. Mixed oxide (MgO-TiO 2) was prepared by using the whole extract from leaves of Piliostigma Thonningii as reducing agent. Structural characterization of the mixed oxide was done using X-ray Diffractometer, High Resolution Scanning Electronic Microscopy and Energy Dispersive X-ray. Petroleum refinery raw wastewater having phenol concentration of 19.961 mg/L was treated using the green-synthesized mixed oxide. Adsorptive phenols removal up to 99.5% was achieved with a dosage of 0.04 g/100 mL at temperature of 35 C, and contact time of 1.167 h. By this, the treated water meets the standard acceptable phenol concentration (0.1 mg/L) in wastewater of hydrocarbon refinery.
