Sintesis Katalis K-Cao Menggunakan Metode Sol-Gel Untuk Transesterifikasi Cpo Menjadi Biodiesel: Variasi Berat Katalis Dan Rasio Mol Minyak:Metanol

Biodiesel is alternative fuel derived from vegetable materials as a substitute for fossil fuels. The raw material for making biodiesel that is often used crude palm oil (CPO). The manufacture of biodiesel is usually used a transesterification reaction using a heterogeneous base catalyst such as CaO. The alkaline catalyst used in this study is CaO catalyst derived from shells of blood clams (Anadara granosa) using the sol-gel method with a ratio between KOH: CKD: Ethylene glycol 0,5: 6: 12 which was calcined at 700, 800 and 900 oC. Catalysts were characterized using XRD to determine the type of mineral, crystal size and crystallinity and XRF to determine mineral composition. The types of minerals contained in the K-CaO-700 catalyst were calcite, portlandite and lime with a crystal size of 45,11 nm and crystallinity 71,98%. The dominant mineral compositions contained in the K-CaO-700 catalyst were CaO and K2O, which were 97,197% and 0,768%. The catalysts were tested in biodiesel synthesis with variations in the weight of catalyst (1, 2, 3 and 4%) and the mole ratio oil: methanol (1:6, 1:12 and 1:18). The maximum biodiesel yield was 95,97%, at the maximum condition of K-CaO-700 catalyst with 2% catalyst weight and 1:12 mole ratio of oil: methanol. The characteristics of the biodiesel produced in this study were water content of 0,019%, specific gravity of 878 kg / m3, viscosity of 6,05 mm2 / s, carbon residue of 0,91%, acid number 0,51 mg KOH / g, soaping number 394,26. mg KOH / g, iodine number 56,86 g I2 / 100 g and cetane number 47,35. The characteristics of biodiesel have met SNI 7182-2015 except for carbon residue and cetane numbers.
