Embodiment 1
[0020] Embodiment 1: A method for carbon dioxide capture and pyrolysis, comprising the following steps:
[0021] 1) Fully dissolve the sodium carbonate solution with the catalyst and the active agent to make a carbon dioxide absorbent solution, in which the catalyst is fully soluble humic acid with a content of more than 5%, or fully soluble fulvic acid; the active agent is a full-soluble humic acid with a content of more than 5%. Soluble biochemical amino acid; the weight ratio of catalyst and carbon dioxide consumption is 0.01%, the weight ratio of activator and carbon dioxide consumption: 0.01%; the carbon dioxide absorbent solution made is sent into the solution batching tank 13, and sent into the carbonization through the sodium carbonate solution pump 14 Tower 2 is sprayed downwards by sodium carbonate dissolving nozzle 15;
[0022] 2) The temperature of the carbonization tower 2 is controlled at 60°C, and the flue gas is sent into the carbonization tower 2 from the flue...
Embodiment 2
[0041] Embodiment 2: a method for carbon dioxide capture and pyrolysis, comprising the following steps:
[0042] 1) Fully dissolve the sodium carbonate solution with the catalyst and the active agent to make a carbon dioxide absorbent solution, in which the catalyst is fully soluble humic acid with a content of more than 5%, or fully soluble fulvic acid; the active agent is a full-soluble humic acid with a content of more than 5%. Soluble biochemical amino acid; the weight ratio of catalyst and carbon dioxide consumption is 0.5%, the weight ratio of activator and carbon dioxide consumption: 0.5%; the carbon dioxide absorber solution that makes is sent into solution batching tank 13, sends into carbonization through sodium carbonate solution pump 14 Tower 2 is sprayed downwards by sodium carbonate dissolving nozzle 15;
[0043] 2) The temperature of the carbonization tower 2 is controlled at 60-70°C, the flue gas is sent into the carbonization tower 2 from the flue gas inlet 1,...
Embodiment 3
[0062] Embodiment 3: a method for carbon dioxide capture and pyrolysis, comprising the following steps:
[0063] 1) Fully dissolve the sodium carbonate solution with the catalyst and the active agent to make a carbon dioxide absorbent solution, in which the catalyst is fully soluble humic acid with a content of more than 5%, or fully soluble fulvic acid; the active agent is a full-soluble humic acid with a content of more than 5%. Soluble biochemical amino acid; the weight ratio of catalyst and carbon dioxide consumption is 0.3%, the weight ratio of activator and carbon dioxide consumption: 0.3%; the carbon dioxide absorbent solution that makes is sent into solution batching tank 13, is sent into carbonization through sodium carbonate solution pump 14 Tower 2 is sprayed downwards by sodium carbonate dissolving nozzle 15;
[0064] 2) The temperature of the carbonization tower 2 is controlled at 66°C, the flue gas is sent into the carbonization tower 2 from the flue gas inlet 1,...
