Abstract: This research aims to develop an optimal continuous process to produce fatty acid methyl esters (biodiesel) from waste cooking oil using a series of shockwave power reactors. Response surface methodology (RSM) based on central composite design (CCD) was used to design the experiment and to analyze five operating parameters: ratio of rotor diameter to stator diameter ( Dr/Ds ), ratio of cavity diameter to rotor diameter ( Dc/Dr ), ratio of cavity depth to gap between rotor and stator ( dc / ?r ), rotational speed of rotor ( N ), and Residence time ( Tr ). The optimum conditions were determined to be Dr/Ds = 0.73, Dc/Dr = 0.06, dc/?r = 0.50, 25,510.55 rpm rotational speed of rotor, and 30.10 s residence times under this condition. Regarding the results, the most important parameter in shockwave power reactor (SPR) reactors was ratio of rotor diameter to stator diameter ( Dr/Ds ). The optimum predicted and actual FAME yield was 98.53% and 96.62%, respectively, which demonstrates that RSM is a reliable method for modeling the current procedure.
