A Study on The Ultrasonic Oil Extraction and Insitu
Effect of ultrasonic power and pulse on oil yield (extraction process) In the in situ process (Figure 2b), it is seen that the increasing of ultrasonic power and pulse will increase the yield gained. Both variables tend to approach their optimum points. The increase of ultrasonic power results in significant yield comparing to ultrasonic pulse.

Alkaline Conventional and in Situ Transesterification
In the present work, the transesterification of cottonseed oil with methanol and ethanol, in the presence of alkali catalyst (NaOH), using low-frequency ultrasonication (24 KHz) and mechanical stirring (600 rpm) for the production of biodiesel fuel was studied. Both conventional and in situ transesterification were investigated. Use of ultrasonication in conventional transesterification with
Use of Ultrasound and Co-Solvents to Improve the In-Situ
The study of the influence of low frequency ultrasound and various alcohol volumes on in-situ transesterification of Chlorella oil involved the use of methanol/Chlorella oil molar ratios of 105:1, 210:1, and 315:1. This corresponds to the use of 20, 40 and 60 ml methanol for the in-situ transesterification of 15 g dry Chlorella biomass.
