Embodiment 1
[0024] Such as figure 1 As shown, the target pyrolysis temperature is set to 550 °C, the target catalytic temperature is 300 °C through the control system, the microwave power is adjusted to 6000 W, the feeding speed is 20 kg / h, and the stirring speed is 60 r / min. At the target temperature, the waste catering oil saponification is continuously added into the microwave reaction chamber through the screw feeder, and the stirrer is pulled up and down to stir, and the saponification of the waste catering oil is rapidly heated and pyrolyzed, and the resulting residue is discharged through the orifice into the residue storage. , the ash-proof partition is set under the orifice to prevent the residue from entering the gas outlet, and the pyrolysis steam enters the upper gas outlet of the slag storage through the high-temperature spherical silicon carbide bed under the negative pressure of the air pump, and then enters the catalyst filling tube for catalytic reforming , and finally th...
