Abstract
A method (20) of making a fuel is disclosed. The method has a first step of exposing a liquid having biologically derived particles therein to an ultrasonic wave producing cavitation in the liquid and release of a precursor of the fuel from at least some of the particles into the liquid (22). The method also comprises the step of exposing the liquid with another ultrasonic wave insufficient to produce substantial cavitation in the liquid, the another ultrasonic wave providing a reaction between the liquid and the precursor to form the fuel (24).
Claims20
A method of making a fuel, the method comprising the steps of:
- (i) exposing a liquid having algal particles therein to a first ultrasonic wave having parameters that produce cavitation in the liquid, the cavitation causing rupture of at least some of the algal particles to thereby release a precursor of the fuel from said at least some of the algal particles into the liquid, wherein the first ultrasonic wave producing cavitation has an intensity of around 50 W/cm2 or higher;
- and
- (ii) exposing the liquid with a second ultrasonic wave, the second ultrasonic wave having parameters that promote a reaction between the liquid and the precursor to form the fuel.
