Abstract

The invention relates to a porous carbon composite material for adsorbing CO2 and a preparation method and application thereof. The material comprises the following components in parts by weight: 100 parts of organic precursor, 1-2 parts of catalyst, 0-300 parts of inorganic template agent and 15-200 parts of polyethyleneimine. The organic precursor, the catalyst and the inorganic template agent are mixed and aged, and then the porous carbon composite material for adsorbing the CO2 is obtained after the processes of drying, carbonization, inorganic template agent removal and the loading of the polyethyleneimine. The material is arranged in a fixed bed adsorption tower to adsorb carbon dioxide. Compared with the prior art, the invention has the advantages of high adsorption capacity, high adsorption selectivity, good high-temperature adsorption effect and good absorption-desorption narrow temperature operation, and water has small influence on the adsorption, and even promotes the adsorption of the carbon dioxide.

Description

technical field

[0001] The invention relates to a composite material and its preparation method and application, in particular to a CO adsorption 2 Porous carbon composite material and its preparation method and application. Background technique

[0002] In recent years, due to the burning of fossil fuels, the concentration of carbon dioxide in the atmosphere has been increasing, and the resulting "greenhouse effect" has become an increasing threat to human production and life. The removal of carbon dioxide in flue gas is a very serious and important task. Urgent task. In addition to the removal of carbon dioxide in flue gas, the removal of carbon dioxide in natural gas, petroleum associated gas, coal gas, and shift gas is also an important task in the chemical process.

[0003] At present, the removal of carbon dioxide mainly includes wet and dry methods. The wet method is mainly the alcohol amine method, which removes carbon dioxide through the process of low temperatur...
