Making waves in the biodiesel industry

The usage of bubbles might be a key advancement in biodiesel production. Philip Adewale, a PhD college student in the Bioresource Engineering Division at McGill, has developed a method to shorten the production period of biodiesel to 20 minutes, a significant drop through previously reported production occasions ranging from 24 to ninety-six hours. The biodiesel has been done from inedible tallow -- a type of animal fat : using enzymes as a switch, and the bursting of pockets formed by ultrasonic dunes, a process known as ultrasonic combining, to speed up the process.

Whilst biodiesel generates significantly less environment pollution than fossil fuels perform, it has been widely disregarded like a viable alternative fuel as it is most often produced from edible vegetation; common sources for biodiesel include canola oil as well as soybean oil.

Adewale informs The Daily, “When you might be using edible canola essential oil, you are competing with human being [consumption]. Down the road, it is going to lead to either high cost or even scarcity. ” To become a much more viable alternative fuel, biodiesel would need to be made from nonedible sources such as animal body fat waste, generated by the meats processing industry and tanneries.

“When you are using harmless canola oil, you are contending with human [consumption]. Down the road, it will lead to possibly high cost or scarcity. ”

Biodiesel can be made from both vegetable oil or animal excess fat. The conversion process does take time, ranging between one hour and some days, depending on a variety of aspects, such as the type of catalyst and also mixing apparatus used. To obtain the shortest production times, businesses use alkaline catalysts, simply because they speed up the reaction more than acid- or enzyme-based catalysts.

Initially, Adewale was interested in making models of the interactions associated with methanol and animal extra fat to see how those 2 reagents mix with each other to create biodiesel. According to Adewale, right after spending two years trying to learn using the modelling software COMSOL, he was told by the software’s producers that what having been trying to do was not really possible. The level of modelling required to simulate the particles blending was too complicated, provided the software that was available at time. “Eventually, I had to drop the concept, ” Adewale explains.

And thus, two years into what he previously hoped would be a three yr PhD, Adewale decided to attempt an experimental approach, because dropping his theoretical modeling approach. He started by learning the characteristics - such as the free fatty acid content along with melting points - various animal fats, such as tallow, lard, choice white oil, and yellow grease, which could be used to make biodiesel.

Adewale noticed tallow experienced a high saturated fat content material which made it semisolid in room temperature, unlike others, which were mostly liquid. Inquisitive as to how this would impact the ultrasound mixing, he made a decision to use waste tallow since the biodiesel source for their experiment.
