Embodiment 1
[0028] Add 0.25g of nano-aluminum particles to 4.7g of bioethanol, put it into a reagent bottle and vibrate for 5 minutes for preliminary mixing, add 0.05g of stearic acid, ultrasonically disperse at 50°C for 20 minutes (ultrasonic power is 80W), and let stand Cool to room temperature to obtain a uniform dark gray fluid fuel without precipitation, as figure 1 as shown, figure 1 Also shown in pure bioethanol. Stand still and observe until it produces obvious precipitation, and the scanning electron microscope picture of the solid particles after precipitation is as follows figure 2 As shown in (a), there are fewer aggregates. Its precipitation time is 336h, such as image 3 shown.
Embodiment 2
[0030] Add 0.25g of nano-aluminum particles to 4.7g of bioethanol, put it into a reagent bottle and vibrate for 5 minutes for preliminary mixing, add 0.05g of oleic acid, ultrasonically disperse at 50°C for 20 minutes (ultrasonic power is 80W), and let stand to cool to room temperature, to obtain a uniform dark gray fluid fuel without precipitation, such as figure 1 shown. Stand still and observe until it produces obvious precipitation, and the scanning electron microscope picture of the solid particles after precipitation is as follows figure 2 As shown in (b), the aggregates are the least. Its precipitation time is 348h, such as image 3 shown.
[0031] The nanofluid fuel that present embodiment obtains carries out ignition combustion test (uses the CO of 400W 2 The laser beam continues to heat 0.1mL of the above-mentioned nanofluid fuel for 1s, the same below), and the highest combustion temperature is 832.4°C, and the combustion time is 1.86s, as shown in Figure 4 ,...
Embodiment 3
[0033] Add 0.25g of nano-boron particles to 4.7g of bioethanol, put it into a reagent bottle and vibrate for 5 minutes for preliminary mixing, add 0.05g of stearic acid, ultrasonically disperse at 50°C for 20 minutes (ultrasonic power is 80W), and let stand Cool to room temperature to obtain a uniform dark brown fluid fuel without precipitation, such as figure 1 shown. Stand still and observe until it produces obvious precipitation, and its precipitation time is 384h, such as image 3 shown.
