Abstract- This Study presents the effect of different parameters that effect the production of biodiesel from used sunflower oil and the optimum conditions using potassium hydroxide as a catalyst. Each biodiesel production (transesterification) run was repeatedthree times. The optimization parameters such as oil to methanol ratio (1:03 to 1:10), potassium hydroxide concentration (0.25 to 2.0 wt %), time duration (15 to 120 min), and temperature ranging from 35 to 70^oC were determined. The optimum parameters were found to be 1 wt % of potassium hydroxide, 1:07 oil to methanol ratio, 60⁰C temperature,90minutes of the reaction time and highest yield of biodiesel obtained was 95 %.

Keywords-Yield, biodiesel, used sunflower oil, transesterification, potassium hydroxide.

I. INRODUCTION

The energy need is increasing continuously due to increase in industrialization and population. Most of the need are supplied through petroleum, coal, natural gases, hydroelectricity and nuclear energy[1]. Expect hydroelectricity and nuclear energy, all other sources will be consumeshortly. Hence it is necessary to seek alternative sources for petroleum.[2],[3] Used oil is the main source to make biodiesel. Transesterification of used oils form biodiesel and glycerin in presence of catalyst. Used oil reduces the cost of biodiesel production[4] and hence should be given priority over other sources[5]. Various catalyst[6] has been used to produce biodiesel from used oil. [11]-[13]

The effect of various parameters on the transesterification reaction for biodiesel production is important from the cost point of view. Several researcher has analysed the effect of parameters on transeterification process[14]-[17].They have used Taguchi method for the design of experiments.[18] Abdul Md.Wakil et-al [20]chosen cotton seed oil, mosna oil and sesame oil as source for biodiesel production. The optimum condition recorded for the methanolysis of crude cotton seed oil were 3 : 1 molar ratio of methanol to oil and 1. 00 % (w/w) catalyst. For mosna oil the optimum condition were established to be 3.5:1 M ratio of methanol to oil and 1.0 % (w/w) catalyst. And for sesame oil the optimum conditions were recorded to be 3.5:1 M ratio of methanol to oil and 1.0% (w/w) catalyst.
