- Abstract
The over-reliance and environmental damage caused by the use of fossil fuels have created the need to explore an alternative source of renewable and clean energy. Free Fatty Acid (FFA) from Hevea brasiliensis oil or commonly known as rubber seed oil (RSO) was utilized as feedstock with the aid of waste mollusk shells (Perna viridis) using domestic household batch microwave irradiation technique. The mollusk shells were sieved to particles sizes ranging from 1 mm to 2 mm and were calcined at 900oC for 4 hours at 5oC/min heating rate. SEM-EDS, XRF, and XRD were performed to characterize the surface morphologies and composition of the catalyst. The two-step esterification-transesterification process reduced the total acid number of RSO from 104.70 mg KOH/g to 0.463 mg KOH/g. The optimum yield of fatty acid methyl ester (FAME) reached up to 96.6% under optimal conditions of 12:1 methanol molar ratio, catalyst loading of 12 weight percent (wt%) oil, 7 minutes of reaction time, and 400-Watt microwave power input. The produced methyl ester fatty acids composition was analyzed via GC-MS and the physicochemical properties such as kinematic viscosity, acid value, flash point, density, water content, and calorific value were analyzed according to the American Society for Testing and Materials D6751 (ASTM D6751) and European Committee for Standardization (EN 14214) and were found to be within the requirements.
