Examples
Embodiment 1
[0021] Weigh 5g of biochar produced by the rapid pyrolysis of corncobs and fill it into the middle of the fixed-bed reactor, and feed it with N 2 Purge at room temperature for 10 minutes to remove the air in the system, and then raise the temperature to 900°C. After the reactor bed reached the target reaction temperature, the N 2 Switch to 95% CO 2 -5%N 2 Mixed gas, gas chromatographic detection of tail gas changes. The test results are shown in Table 1.
Embodiment 2
[0023] Weigh 5g of biochar produced by rapid pyrolysis of rice husk and fill it into the middle of the fixed-bed reactor, and feed N 2 Purge at room temperature for 10 minutes to remove the air in the system, and then raise the temperature to 1200°C. After the reactor bed reached the target reaction temperature, the N 2 Switch to 95% CO 2 -5%N 2 Mixed gas, gas chromatographic detection of tail gas changes. The test results are shown in Table 1.
Embodiment 3
[0025] Weigh 5g of biochar produced by the rapid pyrolysis of rice straw and fill it into the middle of the fixed-bed reactor. 2 Purge at room temperature for 10 minutes to remove the air in the system, and then raise the temperature to 700°C. After the reactor bed reached the target reaction temperature, the N 2 Switch to 95% CO 2 -5%N 2 Mixed gas, gas chromatographic detection of tail gas changes. The test results are shown in Table 1.
