    Sodium hydroxide (NaOH) and potassium hydroxide (KOH) are the most effective catalysts for olive oil due to its low FFA content. Base-catalyzed transesterification works best, eliminating the need for acid pre-treatment. The GlobeCore USB biodiesel unit automates catalyst dosing and reaction control, achieving efficient conversion, even from lower-grade or waste olive oils, ensuring fuel quality and stability.

    回复至: Is peanut oil a biofuel? #317727
    David Lee
    会员

    Yes, peanut oil qualifies as a biofuel feedstock. While not commonly used in its raw form due to high cost and viscosity, it is excellent for biodiesel production through transesterification. The resulting biodiesel offers clean combustion, good lubricity, and high cetane numbers. When processed with the GlobeCore USB plant, peanut oil yields a high-quality, renewable fuel compatible with diesel engines, contributing to energy diversification and reduced environmental impact.

    回复至: How to make fuel from coconut? #317610
    David Lee
    会员

    Fuel from coconuts can be made in two main ways: from coconut oil (biodiesel) or coconut shell (biochar or syngas). For biodiesel, oil is extracted, filtered, and reacted with methanol and a catalyst. The GlobeCore USB system performs this with automation and precision, producing fuel for diesel engines. Coconut shells can also be converted into energy through pyrolysis or gasification. These methods provide renewable energy options from both oil and biomass components of the coconut.
