Biodiesel Production from T ung Seed Oil using Strong Base Supported on Activated Carbon from Longan as Catalyst by Microwave Technique
Keywords:activated carbon, biodiesel production, longan, microwave, tung seed oil
This research project studied biodiesel production from tung seed oil via transesterification reaction using catalysts supported activated carbon from low grade longan, sodium hydroxide associated with activated carbon (NaOH/AC). The reaction conditions were varied as follow; molar ratios of oil to methanol 1 : 8 – 1 : 16, amount of catalysts 1 – 5 wt%, reaction temperature of 65 °C and reaction time for microwave of 5 minutes. It was found that the highest yield of biodiesel was 84.41% when using the ratio of oil to methanol 1:8 with 1 wt% catalyst, reaction temperature 65 °C and reaction time 5 minutes. Physical and chemical properties of biodiesel were studied. Purity of biodiesel was determined by gas chromatography mass spectrometry (GC-MS) technique. The result showed that the biodiesel purity was 99.96%.
