Sodium hydroxide (NaOH) and potassium hydroxide (KOH) are widely used for base-catalyzed transesterification of peanut oil. Acid pre-treatment is generally not required unless free fatty acid (FFA) levels are high. The GlobeCore USB system supports both base and acid catalysis, allowing flexibility based on oil quality. Its automation ensures the precise dosing of chemicals, temperature stability, and effective reaction time, resulting in a high-yield and high-purity biodiesel.
