Article Synopsis
- This paper discusses the energy efficiency of using microwave heating for esterifying free fatty acids with a heterogeneous catalyst.
- Under the specified conditions (5 wt% sulfated zirconia, 1:20 oil to methanol ratio, 60°C, atmospheric pressure), microwave heating achieved over 90% conversion in just 20 minutes compared to 130 minutes with conventional heating.
- The microwave process consumed only 67% of the estimated minimum heat energy needed, highlighting its effectiveness in reducing reaction time and energy consumption.
