Sintesis Biodiesel Dari Cpo Menggunakan Katalis Heterogen H2so4/ Cao, Variasi : Rasio Mol Minyak : Metanol Dan Waktu Reaksi

Biodiesel is an alternative energy that is environmentally friendly and has low exhaust emissions when used in diesel engines. Biodiesel synthesis is carried out using the main ingredient, namely palm oil (CPO), but the high content of free fatty acids (FFA) (> 5%) contained in CPO is one of the factors that affect the performance of the catalyst. To overcome this problem, in this study, biodiesel was synthesized in one reaction stage. This research used CaO catalyst from blood clam shells (Anadara granosa) which was calcined at 900oC for 5 hours and then impregnated using sulfuric acid 1, 2, and 3 M and recalculated at 300 oC for 3 hours to produce H2SO4 1 catalyst, 2, and 3M / CaO. The impregnated catalysts were then characterized using XRD to determine mineral types and FTIR to determine functional groups and acidity. The reaction conditions studied were the mole ratio of oil: methanol (1:6, 1: 9, 1:12, 1:15, 1:18) and reaction time (1, 2, 3, 4 hours). The maximum yield of biodiesel obtained was 96.69% under conditions of 1:12 mole ratio of oil: methanol and a reaction time of 3 hours with a concentration of 3
M. The maximum yield of biodiesel was characterized based on biodiesel quality standards, among others; water content 0.023%, specific gravity 886 kg/m3, viscosity 3.95 mm2/s, carbon residue 0.02%, acid number 0.46 mg KOH/g, saponification number 393.98 mg KOH/g, iodine number 57,01 g-I2/10g and cetane number 47.50. In general, the characteristics of biodiesel meet the quality requirements of SNI 7182-2015 except for cetane numbers.
