| Summary: | In this study, microwave irradiation-assisted transesterification was used to produce Ceiba pentandra
biodiesel, which accelerates the rate of reaction and temperature within a shorter period. The
improvement of biodiesel production requires a reliable model that accurately reflects the effects of input
variables on output variables. In this study, an extreme learning machine integrated with cuckoo search
algorithm was developed to predict and optimize the process parameters. This model will be useful for
virtual experimentations in order to enhance biodiesel research and development. The optimum parameters of the microwave irradiation-assisted transesterification process conditions were obtained as
follows: (1) methanol/oil ratio: 60%, (2) potassium hydroxide catalyst concentration: 0.84%(w/w), (3)
stirring speed: 800 rpm, and (4) reaction time: 388 s. The corresponding Ceiba pentandra biodiesel yield
was 96.19%. Three independent experiments were conducted using the optimum process parameters and
the average biodiesel yield was found to be 95.42%. In conclusion, microwave irradiation-assisted
transesterification is an effective method for biodiesel production because it is more energy-efficient,
which will reduce the overall cost of biodiesel production. |
