Abstract

The invention discloses a preparation method for an absorbent for smoke decarburization. The preparation method comprises the following steps: using a boron nitride nano-sheet / montmorillonoid intercalation composite material, preparing a polysiloxane crosslinking compound on the surface of the composite material, and uniformly mixing with fluorite powder, calcium carbonate, sodium silicate and silicon nitride, die-filling, degassing, and compression-forming, drying an obtained rough body and placing in a muffle furnace for sintering, to obtain a porous carrier; adding ethyl succinate to diethyl carbonate, stirring and uniformly mixing, to obtain mixed solution B; adding the prepared porous carrier to the mixed solution B, soaking for 15 h, centrifugally removing the unadsorbed mixed solution after soaking, and finally drying the porous carrier adsorbed with the mixed solution, to obtain the compound absorbent. The prepared absorbent by the method has the large absorptive capacity, and is capable of effectively removing carbon dioxide in the smoke.

Description

Technical field: [0001] The invention relates to the field of air pollution control, in particular to a method for preparing an absorbent for flue gas decarbonization. Background technique: [0002] Global CO 2 A large amount of emissions of the greenhouse effect intensified, resulting in an increase in the average temperature of the earth's lower atmosphere and climate anomalies. Global CO in 1995 2 The total emissions reached 22 billion tons. CO control 2 The emission of CO2 is attracting the attention of the international community. At present, countries all over the world are actively studying CO2 emissions. 2 emission reduction measures. One of the emission reduction measures is to reduce the main CO 2 CO emitted by the source 2 Separation, recovery and utilization. This is a realistic approach when it is difficult to fundamentally change the energy structure. Fossil fuel power plants are CO 2 of concentrated emission sources, whose CO 2 Emissions account for...
