Trans-Esterification of Crude Palm Oil Liquid Waste to Biodiesel

Abstract

Esterification and trans-esterification reactions are an alternative solution for the production of biodiesel from Crude Palm Oil waste. The two previous studies show that the yield obtained was less than 80%. It is necessary to investigate the optimum condition of trans-esterification operation in biodiesel production from CPO waste. Variables used are temperature, time, ratio of molar triglyceride with methanol, and catalyst concentration. According to preliminary temperature treatment variations, it is determined that optimum temperature is 55°C. Meanwhile, the time treatment variations showed that optimum time is 60 minutes. For the ratio of molar triglyceride with methanol, it is determined that 1:10 is the optimum ratio. And last, for the experiment variations of NaOH concentrations it is discovered that the optimum concentration is 1.25%-b. And to conclude the research, the optimum condition for each variable was used where biodiesel’s yield can reach up to 96.67%.
