Production of biodiesel from waste cooking oil using ultrasonic tubular reactor
The aim of study is to produce the synthesis of biodiesel from waste cooking oil (WCO) using ultrasonic tubular reactor at laboratory scale. The experiment was used to determine the effect of ester contents by reaction time, molar ratio of WCO to Methanol (MeOH), amount of catalyst, frequency...

| 总结: | The aim of study is to produce the synthesis of biodiesel from waste cooking oil
(WCO) using ultrasonic tubular reactor at laboratory scale. The experiment was used
to determine the effect of ester contents by reaction time, molar ratio of WCO to
Methanol (MeOH), amount of catalyst, frequency of ultrasonic and ultrasonic output
power using ultrasonic tubular reactor. Based on the optimum process by ultrasonic
tubular reactor, a comparisons study of three different processes (ultrasonic tubular
reactor, conventional ultrasonic cleaner and mechanical stirring) were also
investigated. The optimum results of biodiesel process using ultrasonic tubular
reactor are the reaction time of 5 minute, sodium hydroxide (NaOH) catalyst 1%wt
of WCO, molar ratio WCO to MeOH of 1:6, frequency ultrasonic of 20 KHz and
ultrasonic output power of 650 Watt. The reaction time was reduced to 12-24 times
(minute) compare to mechanical stirring and the ester contents was obtained at
96.54%wt. The ternary phase diagram ultrasonic tubular reactor was to find out the
liquid liquid-equilibrium base on WCO- Fatty Acid Methyl Esters (FAME) -MeOH.
The results show that by increasing the residence time of the whole reactant system
within the two-phase zone is good for the reaction transesterification on ultrasonic
tubular reactor. The semi continuous ultrasonic tubular reactor for biodiesel process
of WCO gave conversion of WCO to FAME of 98%wt with flow rate of 5.56 ml/s.
Meanwhile, the pilot plan of biodiesel facilities using mechanical stirring method
(capacity of 100 kg WCO/batch) was designed and the transfer knowledge about
biodiesel process was a success between the university with industry in Batu Pahat. |
