Description:India needs to promote bio fuels for meeting out the energy demands in the upcoming years. For that, biodiesel produced from the goat fat oil can be used as a solution. Biodiesel can be produced in single step process or double step process based on the free fatty acid content. Biodiesel produced from a process known as transesterification process involving the reaction of oil with an alcohol in the presence of a catalyst for the conversion of triglycerides into fatty acid methyl esters and glycerine. For the biodiesel production, first free fatty acid content was tested in the goat fat oil. It was found that free fatty acid content was 0.56. Therefore, biodiesel from goat fat oil was produced through the transesterification process in a single step. For production, five kg of goat fat waste was collected and after melting process, three litres of goat fat oil was obtained from that process. After that, 728 ml of methanol and 15 g of NaOH was taken in a glass beaker and mixed with a magnetic stirrer for ten minutes. Three litres of goat fat oil was taken in a three-neck ground bottom flask and catalyst mixture (Methanol + Sodium hydroxide) was mixed with the oil in the ratio of 1:6 at 60°C (for one mole of oil, six moles of methanol was used for the production of biodiesel). The transesterification reaction time was kept for ninety minutes. After this reaction time through gravity separation process, crude biodiesel was separated in the top layer and crude glycerine was separated in the bottom layer. After separation of crude biodiesel, it was washed with hot water at 60°C in the ratio of 1:1 (i.e. for one liter of oil, one liter of water was added) in a separating funnel. This process was repeated until the wash water pH becomes neutral. After three washes, pH value got neutral. Then, biodiesel was dehydrated using a glass beaker at 110°C by using a heating mantle for the removal of water from biodiesel. By measuring the quantity, it was found that 2.7 liters of biodiesel was obtained after washing process. It was found that with the methanol and sodium hydroxide catalyst, biodiesel produced from the goat fat oil was 90% efficiency. It can be used with blending of diesel fuel. This fuel can be used as an alternative fuel with the blending of diesel for automobile industries. It can be used for reducing diesel consumption in automobiles. , Claims:1. Biodiesel was produced from the goat fat with the yield of 90%, from the process involving reaction of goat fat oil with methanol and Sodium hydroxide in the ratio of 1:6.
