Embodiment 1
[0046] The embodiment of the present invention describes a method for nitrogen-rich catalytic pyrolysis to co-produce nitrogen-containing heterocyclic chemicals and nitrogen-doped carbon. The method specifically includes the following steps:
[0047] S1: After crushing the sawdust, soak it with excess wood vinegar for 24 hours to remove impurities such as alkali metals in the sawdust, filter, rinse and dry to obtain pickled raw materials, the drying temperature is 105°C, and the drying time is 24 hours ,
[0048] S2: Fully mechanically mix the acid-washed sawdust with the green activator, the green activator KHCO 3 The mass ratio with sawdust is 1:20 to obtain a mixed sample,
[0049] S3: Put 2g of the mixed sample into the first stage of a two-stage fixed-bed reactor (diameter 45mm, length 60cm), and feed pure ammonia gas for nitrogen-enriched pyrolysis reaction, ammonia gas and green activator KHCO 3 The synergistic effect promotes the pore-forming reaction of sawdust mixe...

[0056] S1: After crushing the sawdust, soak it with excess wood vinegar for 24 hours to remove impurities such as alkali metals in the sawdust, filter, rinse and dry to obtain pickled raw materials, the drying temperature is 105°C, and the drying time is 24 hours ,
[0057] S2: Fully mechanically mix the acid-washed sawdust with the green activator, the green activator KHCO 3 The mass ratio with sawdust is 1:15 to obtain a mixed sample,
[0058] S3: Put 2g of the mixed sample into the first stage of a two-stage fixed-bed reactor (diameter 45mm, length 60cm), and feed pure ammonia gas for nitrogen-enriched pyrolysis reaction, ammonia gas and green activator KHCO 3 The synergistic effect promotes the pore-forming reaction of sawdust mixed with nitrogen. The reaction temperature is 550°C, the reaction time is 20min, and the ammonia flow rate is 200mL / min.
[0059] S4: Pass nitrogen-rich pyrolysis volatiles into the second stage of the two-stage fixed-bed reactor, and carry out ...
Embodiment 3
[0065] S1: After crushing the sawdust, soak it with excess wood vinegar for 24 hours to remove impurities such as alkali metals in the sawdust, filter, rinse and dry to obtain pickled raw materials, the drying temperature is 105°C, and the drying time is 24 hours ,
[0066] S2: Fully mechanically mix the acid-washed sawdust with the green activator, the green activator KHCO 3 The mass ratio with sawdust is 1:10 to obtain a mixed sample,
[0067] S3: Put 2g of the mixed sample into the first stage of a two-stage fixed-bed reactor (diameter 45mm, length 60cm), and feed pure ammonia gas for nitrogen-enriched pyrolysis reaction, ammonia gas and green activator KHCO 3 The synergistic effect promotes the pore-forming reaction of sawdust mixed with nitrogen. The reaction temperature is 600°C, the reaction time is 40min, and the ammonia flow rate is 500mL / min.
