    Heterogeneous Catalysis of Second Generation Oil for Biodiesel Production: A Review
    (Wiley-VCHGmbH: ChemBioEngRev, 2021) Fatai A. Aderibigbe; Suleiman Shiru; Saka, H. B.; Amosa, M. K.; Sherif Ishola Mustapha; MohammedIAlhassan; Ayoade L. Adejumo; Morufudeen Abdulraheem; Owolabi, R. U.
    Abstract The demand for cleaner fuels has been on the rise lately, prompting researchers to explore alternative cleaner technologies to meet the growing demand. This has led to the introduction of renewable fuels such as bioethanol and biodiesel. Depending on the feedstock employed for production, renewable fuels can be divided into first, second, and third genera tion. Reliance on first generation biofuel feedstocks has led to inherent competition between foods versus fuels in the society in the last decade. Further technological prospects in research and develop ment have provided insight into the use of second generation biofuel feed-stocks from non-edible agricultural waste products, energy crops, and crop residues. Zeolites and modified zeolites as heterogeneous catalysts have been highly prospec tive for the transesterification process of these oils. Modified zeolite can act as a bi-functional catalyst because of its acidic and basic sites. Here, a review of transesterification reaction technology, zeolite and modified zeolite as a heterogeneous catalyst to generate biodiesel was discussed. Cur rent status, challenges and future prospects are also discussed. Keywords: Biodiesel, Heterogeneous catalyst, Homogeneous catalyst, Transesterification, Zeolite

    Waste Cooking Oil Conversion to Biodiesel Using Solid Bifunctional Catalysts
    (Wiley-VCH GmbH: ChemBioEng Rev. 2023,, 2023) Fatai Alade Aderibigbe; Harvis Bamidele Saka; Sherif Ishola Mustapha; Mutiu Kolade Amosa; Suleiman Shiru; Idowu Abdulfatai Tijani; Esther Oluwabunmi Babatunde; Bisola Taibat Bello
    Abstract The draining of fossil fuels and their toxic influence on the environment has prompted the need for alternative fuels known as biofuels. Of the various types of biofuel, biodiesel has attracted wide interest in the world today since it promotes carbon neutral ity. The transesterification and interesterification process remains the most widely used process route for biodiesel production. In this review, the perfor mance efficiency of solid base, solid acid, and bi functional solid acid-base catalysts for biodiesel pro duction from waste cooking oil is considered. In particular, the benefit of exploring the biomass derived acid-base heterogeneous bifunctional cata lysts, current status, and future prospects for biodie sel production from waste cooking oil are eluci dated. Keywords: Acid-base bifunctional catalysts, Biodiesel, Biomass, Solid catalyst, Waste cooking oil
