I am Praniesh, studying final year Industrial Biotechnology in Government College of Technology, Coimbatore. I am currently doing my project in "biodiesel production from mahua oil", the oil has a FFA% of 18. I did two step acid pretreatment using 0.35 v/v and 0.30 v/v methanol and 1% h2so4 to reduce the FFA but i could reduce it only to 4 not less than that. I tried it several times but still couldnt reduce it. I performed alkali transesterification reaction and it resulted in soap formation. So what should i do to reduce the FFA less than 1? should i change the quantity or is there any other alternative method? kindly reply me, thanks..
