Optimization of free fatty acid reduction in waste frying oil via sulfamic acid-catalyzed esterification
บทคัดย่อ ( Abstract )
ABSTRACT This study presents the esterification process using sulfamic acid as a catalyst for pretreatment of high free fatty acid (FFA) waste frying oil (WFO), which contained FFA 3.34% w/w. The acid catalyzed esterification with methanol was carried out to investigate the optimum condition for the reduction of FFA content in WFO. Also studied were the effects of reaction variables which included methanol amounts of 20-50% v/v, catalyst amounts of 0-9% w/v of oil, reaction temperatures of 31-60 oC, and reaction times of 0.5-4 hrs. The FFA content from each reaction condition was determined by AOAC Official Method 940.28 (AOAC 2012). The optimum condition was achieved at a methanol amount of 50% v/v, a catalyst amount of 7% w/v of oil, a reaction temperature of 60 oC, and a reaction time of 2 hrs. At the optimum condition, there was 0.93% w/w of FFA in oil product.
