- W2113804580 abstract "Rubber seed oil (RSO), Free fatty acid (FFA), Acid esterification, Central Composite Design (CCD), Response Surface Methodology (RSM). Rubber seed plantations in Malaysia are one of the copious non-edible and un-utilized feedstock available for alkyl esters production. The free fatty acid content in feedstock needs to be in adequate limits for quality biodiesel. Current research was conducted on the reduction of FFA content in Rubber Seed Oil (RSO) by using experimental design software Design Expert 8.0. Central Composite Design (CCD) was implemented for experimental design and an optimized condition was found by RSM. Four basic parameters affecting acid esterification process were studied which comprise of alcohol to oil molar ratio, catalyst amount (wt %), reaction temperature ( o C) and reaction time (min). Parametric studied was conducted within the ranges of alcohol to oil molar ratio (from 10 to 15); catalyst amount (from 5-10 wt %); reaction temperature (from 4565 o C); and reaction time (from 55-90 min). Statistical significance of each parameter was conducted by Analysis of Variance (ANOVA). Optimum conditions for an acid esterification reaction that reduce the FFA content of RSO to 0.82% was found to be at 15:1 alcohol to oil ratio, temperature of 45 o C, catalyst amount of 10wt% (oil basis) and reaction time of 90 min. The RSO feedstock was characterized and compared before and after acid esterification process." @default.
