The novel continues biodiesel using ultrasound clamp tubular reactor

Jatropha curcas oil (JCO), is used as the feedstock in this research work. The work starts with design a new continuous process for biodiesel using ultrasound clamp on tabular reactor for producing pure biodiesel from jatropha curcas oil (JCO). Form this design, we fabricate the rig and test the application of sonochemistry technique in biodiesel production through optimal and low cost production technique for enhancing their capabilities and effective process. Before run process of biodiesel the analysis of physical and chemical properties of the feedstock and the associated product to obtain the major fatty acid compositions of triglycerides applicable in the jatropha curcas oil. Based on testing the free fatty acid of jatropha curcas oil is above 10.1 %. So for reduce free fatty acid we need do esterification process using l%w/w of acid catalyst and molar ratio methanol to oil is IS: 1 . After esterification, the free fatty acid of the feedstock was testing and the result is 0.402%. It is important because is too high free fatty acid it cause smaller the conversion efficiency. The next stage is transesterification conducted with 6: 1, 9; 1 and 12: 1 molar ratio methanol to jatropha for reaction times of 3, 5 and 7 minutes for 1% catalyst sodium hydroxide (NaOH) at a temperature of 65OC with frequency arrange 17Hz to 22kHz and ultrasonic power output 240watt. The standard physical properties test to determine the biodiesel qualities are flash point, water content, acid value, density and dynamic viscosity. From test bed for continuous reactor using tubular reactor the maximum producing biodiesel is 89 % was obtained with molar ratio methanol to oil 6: 1 at 7 minutes reaction time.
