Abstract

Kepyar castor oil has not been widely used. Therefore, this kepyar castor oil needs to be processed, among others by the process of alcoholy sis, using catalysts from the Pertamina unit III Palembang oil cracking waste, which is also a waste, so that it can be utilized. Alcoholy sis of used cooking oil in more than one atmospheric pressure at the exhaust catalyst for petroleum cracking Pertamina unit III Palembang, run in a three-neck rounded flask, equipped with a thermometer, heater and stirrer. At first, three-neck rounded flask filled with kepyar castor oil, alcohol, and catalyst to a certain amount, then powerstat heater and stirrer is turned on and set. Samples were taken at each interval of 10 minutes and then the lower layers of glycerol levels were analyzed by acetine. In a certain range, an increase in temperature, the percentage of catalyst, stirring rotation, and ethanol-oil ratio, resulting in increased glyceride conversion. Alcoholic analysis of kepyar castor oil follows pseudo first-order reactions to glycerides. The process is relatively good, found in 60 minutes, temperature 110 C, catalyst percentage 2.5%, stirring speed 320 ppm, and alcohol-oil ratio 6 mg/mg. In that situation the conversion reached 0.7099 parts. Keywords: Alcohol Sis, Biodiesel, Kepyar Castor Oil, Used Catalyst.
