Ultrasonic transesterification of oil to
biodiesel
Ultrasonication can improve the conversion processing of vegetable oils or animal fats to biodiesel by improved mixing and enhanced chemical activity
Ultrasonication can improve the conversion processing of vegetable oils or animal fats to biodiesel by improved mixing and enhanced chemical activity The manufacturing of biodiesel from oils (e.g soy, canola, sunflower seed) or animal fats, involves the base-catalysed transesterification of fatty acids with methanol to give the corresponding methyl esters

Algae oil feedstock for biodiesel manufacturing
Algae is an alternative to popular feedstocks, like soybean, canola and palm: ultrasonication improves the extraction of oil from the algae cells and the conversion to biodiesel
The conventional esterification reaction in batch processing tends to be slow, and phase separation of the glycerol is time-consuming.
Ultrasound allows for in-line processing.
Ultrasonication can achieve a biodiesel yield in excess of 99%.
Ultrasound reduces the processing time from the conventional 1 to 5 hour batch processing to less than 5 minutes.
Ultrasonication can also help to reduce the separation time from 5-10 hours (using conventional agitation) to less than 15minutes using ultrasound.
The biodiesel processing does not need much ultrasonic energy.
Hielscher is supplies industrial ultrasonic processing systems, worldwide.
With ultrasonic processors of up to 16kW power per single device, there is no limit in plant size or processing capacity.
THE COSTS.
The resulting costs for the ultrasonication vary between 0.2UScents and 1.5UScents per litre when used on a commercial scale. Request a free brochure from Hielscher USA ...
