A method for preparing biodiesel from palm oil, which includes hydrating and degumming crude palm oil, distilling and deacidifying, dehydrating and drying, and then adding low-carbon alcohol and a catalyst to perform a transesterification reaction to obtain crude biodiesel and crude glycerol; evaporating them to separate low-carbon The alcohol is used to obtain finished biodiesel and by-product glycerin, and the evaporated low-carbon alcohol is recovered and recycled. The present invention uses palm oil as raw material, which has sufficient raw material sources and low price and production cost; impurities such as phospholipids, free fatty acids and water in crude palm oil are removed through hydration degumming, distillation deacidification, dehydration and other processes, thereby avoiding these problems. The impact of impurities on the subsequent transesterification reaction catalyst is beneficial to improving the conversion rate and rate of biodiesel; and by using efficient solid catalysts, the yield of biodiesel is increased, the process flow is simplified, and environmental pollution is significantly reduced, thereby making This technology is more economical.
