PRODUKSI BIODISEL DARI MINYAK GORENG BEKAS MENGGUNAKAN KATALIS CaO CANGKANG KERANG DARAH KALSINASI 900 °C
Abstract
Biodiesel is one of the most potential alternative energy for diesel machine since it is
renewable and environmental friendly. Biodiesel can be produced by transesterification
reaction of vegetable oil or animal fat with alcohol and catalyst addition. In this study,
biodiesel was produced by transesterification reaction of waste cooking oil and
methanol using a CaO catalyst of blood cockle shells (Anadara granosa). Blood cockle
shells (Anadara granosa) can be used as heterogeneous catalysts for biodiesel
production because it contains CaCO 3 that can be decomposed into CaO.
Decomposition of the blood cockle shells as heterogeneous catalyst for biodiesel
production was carried out at 900 oC for 5 hours. The yield of biodiesel optimum was
81.67% with 3% weight of catalyst, 1:15 of oil and methanol mole ratio, 3 hours of
reaction time and 60±2 oC of reaction temperature.
