[0029] Example 1
[0030] The continuous production of carbon nanotubes by catalytic cracking of methane includes the following steps:
[0031] Step 1. Close the feed pipe 3 and the discharge pipe 6, open the exhaust pipe 7, and enter the nitrogen gas into the gas inlet pipe 4, and pass it into the reactor 1 for 10 minutes; repeat 3 times to remove the air in the reactor 1;
[0032] Step 2. Adjust the inclination angle of reactor 1 to 0 degrees, rotate at a speed of 8-20r / min, heat furnace 2 to 500-600℃, change the gas of inlet pipe 4 to hydrogen, and change the La2NiO4 of feed pipe 3 The catalyst powder enters the reactor 1 along with the hydrogen, and reduces the catalyst for 20-30 minutes;
[0033] Step 3. Adjust the temperature of the heating furnace 2 to 700°C~900°C, adjust the inclination angle of the reactor 1 to -5~-8 degrees, and rotate in the opposite direction at a speed of 10~15r / min for 10~20min; change the gas in the inlet pipe 4 At the same time, adjust the inclination...
