    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.

    en réponse à : Is peanut oil a biofuel? #317727
    David Lee
    Membre

    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.

    en réponse à : How to make fuel from coconut? #317610
    David Lee
    Membre

    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.

    en réponse à : How are bitumen emulsion spray systems calibrated for accuracy? #131540
    David Lee
    Membre

    Calibration involves setting flow rates, adjusting nozzle angles, and testing spray patterns to ensure even coverage and proper application rates in the field.

    en réponse à : How does asphalt emulsion contribute to energy savings in paving? #131383
    David Lee
    Membre

    Asphalt emulsion is applied at ambient or lower temperatures, eliminating the need for heating and reducing fuel consumption. This results in significant energy savings during production and application.

    en réponse à : Why is emulsion quality control crucial in asphalt production? #131030
    David Lee
    Membre

    Quality control ensures the emulsion meets specifications, providing consistent performance and durability. It prevents issues like poor adhesion, uneven application, or premature breaking. Regular testing improves reliability, reduces costs, and enhances pavement longevity.

    en réponse à : What is an emulsion tack coat and when is it used? #130921
    David Lee
    Membre

    The thickness of an emulsion tack coat typically ranges from 0.1 to 0.3 gallons per square yard, which translates to a film thickness of about 0.5 to 2 mils (15 to 50 microns). This thin application is designed to create a bond without adding significant weight or thickness to the pavement structure. Proper calibration and application techniques are essential for achieving the desired coverage and effectiveness.

    en réponse à : What is the latest technology in fuel oil polishing? #122574
    David Lee
