Examples
Embodiment 1
[0039] Embodiment 1, refer to figure 1 . This example takes the inverted U-shaped tube reactor 1 as an example, and by every liter of methanol (CH 3 OH) dissolves about 25.01 grams of sodium methylate (NaOMe) to prepare a mixture of methanol and catalyst, close valve 1, and store the mixture in vessel 21. Before production, CH 3 OH and NaOMe were mixed at 40°C for 1 hour. Adjust the frequency to 5Hz, the amplitude to 4mm, turn on the oscillation device, and adjust the metering pump 24: make CH 3 The flow rate of OH+NaOMe mixture is 0.509l / h, the flow rate of rapeseed oil is 2.591l / h, the reactants (catalyst-containing methanol and rapeseed oil) are extracted from the respective vessels, and heated to 60°C and input into reactor 1 . After the reaction is completed under the above parameters, the product (crude biodiesel+glycerin) first enters the separator 34 for separation, and the separated methanol-containing crude biodiesel enters the water washer 32 to wash away the m...
Embodiment 2
[0041] Embodiment 2, when a large production volume requires multi-level strengthening, it can be used figure 2 or 3 options. All the other are with embodiment 1.
Embodiment 3
[0042] Embodiment 3, the embodiment of the reactor of other forms is as Figure 7-13 , 20-28. All the other are with embodiment 1. When the diameter of reactor 1 is bigger, can adopt hollow piston 5, refer to Figure 7 , 8 , 26-28.
