Biodiesel Production from Acidic Crude Palm Oil Using Perchloric Acid

摘要

Perchloric acid was used as a catalyst for the treatment of free fatty acid (FFA) in acidic crude palm oil (ACPO). Perchloric acid shows reduced the FFA content from 8.8% to 1% using 1% of acid to ACPO and the conversion of FFA to fatty acid methyl ester (FAME) was 88%. The produced biodiesel from treated ACPO meets international biodiesel standards such as EN 14214 and ASTM D6751. Perchloric acid shows high catalytic activity for the conversion of FFA to FAME and can be used to treat a wide range of acidic oils and fats.
