Abstract

Biodiesel is one of the alternative energy made from the transesterification reaction between vegetable oils and methanol. One potential source of vegetable oil to be developed in Indonesia is bintaro seed oil. Plant bintaro as a non-food crop so it will not compete with food needs as well as cultivated plants are now widely used as an ornamental plant reforestation and on the edge of the highway. This study aims to create crude biodiesel from oil of the seeds bintaro.

Abstract

Surfactant (surface active agent) is a chemical compound used to reduce the surface tension of the liquid. Surfactants are divided into four groups: anionic, nonionic, cationic and amphoteric. The most widely used surfactant is an anionic surfactant which is synthesized from Linier Alkylbenzene Sulphonate (LABS) a petroleum base surfactant. LABS is not ecofriendly, low resistant to high salinity levels, hard to degradable, expensive and still imported. Methyl Ester Sulfonate (MES) is an anionic surfactant which is currently being developed. These surfactants can be produced from POME. MES produced by sulfonation reaction with addition of sulfonation agents. In this research sodium bisulfite used as sulfonation agent. The aims of this research was to synthesized MES from POME and Sodium Bisulfite (NaHSO3) and Calcium Oxide as the catalyst, to characterize the product, and to study the effects of mole ratio and stirring speed of surface tension and emulsion stability MES. POME obtained from PT. Cemerlang Eka Perkasa Dumai Riau Province. Sulfonation process was carry out at the mole ratio of 1:1, 1:1,5 and 1:2, stirring speed of 300, of 500, of 700 rpm, temperature of 80°C, and the time of 6 hours.

Abstract

Calcium oxide (CaO) is a heterogeneous solid base which is generally used as a catalyst in making biodiesel. It is mainly obtained from cement clinker and activated through calcination method. The purpose of this study was to determine the effect of using cement clinker catalyst on the yield of the biodiesel. A batch reactor with a condenser was used in making the biodiesel under favorable conditions such as calcination temperatures of 700 °C, 750 °C and 800 °C, time of 5, 6 and 7 hours, and catalyst concentration of 1%-w, 2%-w, and 3%-w oil. The analysis involved X-Ray Diffraction (XRD) and Brunauer-Emmett-Teller (BET) for catalysts and Gas Chromatography-Mass Spectrometry (GC-MS). The catalyst calcination temperature determined the optimum conditions. From this study, the conditions necessary for transesterification reaction include the mole ratio of methanol/oil of 6 to 1, the temperature of 70 °C for 2 hours and 700 °C for 5 hours, and catalyst dosage of 2% by weight. Under these conditions, the yield of the biodiesel was 84.26%. Additionally, at the calcination temperature of 800 °C for 7 hours and catalyst dosage of 3% by weight, the yield of the biodiesel was 76.84%. CaO, SiO2, 2CaO.SiO2 and 3CaO.SiO2 were found in the catalyst through XRD analysis. The specific surface areas of the catalyst were 25,497 m2/g (700 °C/5 hours) and 35,879 m2/g (800 °C/7 hours) through BET analysis. According to the GC-MS analysis, the main components of the biodiesel include methyl palmitate, methyl oleate, and methyl stearate.
