การผลิตไบโอดีเซลแบบต่อเนื่องจากน้ำมันปาล์มบริสุทธิ์ด้วยโนโวไซม์ 435 โดยใช้เทอร์เชียรีบิวทานอลเป็นตัวทำละลายร่วม

Abstract

The results of continuous biodiesel production from refined palm oil catalyzed by Novozym 435 using t-butanol as a co-solvent in packed bed reactor showed that the optimal condition for this system was volume ratio of t-butanol to oil as 1:1, molar ratio of methanol to oil as 6:1, temperature of reaction as 40 oC, flow rate of substrate solution as 0.25 ml/min, and amount of Novozym 435 as 3 g. After continuously producing biodiesel with this optimal condition for 1 month (720 hours), the results showed slightly decreased in conversion and production rate with 90.10% of average 1 month conversion, and 12.22 mmol/g/h of average 1 month production rate, respectively.
