Description
Technical field
The present invention relates to a kind of preparation method of activated carbon, relates in particular to a kind of efficient absorption CO2It is biomass-based
The preparation method of activated carbon.
Background technology
At present, resource, energy crisis and environmental problem become increasingly conspicuous, and how treatment and use agricultural wastes have become the world
One of various countries' focus of attention.Pericarppium arachidis hypogaeae, walnut shell, green shell are huge in China's yield, and general these agricultural wastes do not have
There is value, processed into destructor plant as rubbish, but as these biological mass shell phosphorus content are high, be extensively easy to get
And advantage with low cost, can be as the preferable presoma for preparing activated carbon, therefore with these biological mass shells as forerunner's system
Standby activated carbon can both reduce the quantity of house refuse, can develop the new application of these biological mass shells again, prepare efficient
CO2Adsorbing material.
Since the industrial revolution, the Fossil fuel such as a large amount of burning coals, oil gives off a large amount of CO2Gas, in causing air
Greenhouse gas concentration increase year by year, heavy damage ecological environment endangers the survival and development of the mankind.Therefore, implement CO2
Capture and enrichment with important theoretical and practical significance.At present, trap CO2Main method have liquid phase scrubbing method, solid-state
Absorption method, membrane separation process etc..Wherein liquid phase scrubbing method has to equipment severe corrosive, absorbent regeneration energy consumption big and is easily oxidized easy
Degraded；Membrane separation process there are problems that separation efficiency it is relatively low, limit its application.By contrast, solid absorption method behaviour
Make relatively easy, it is little to the corrosivity of equipment, it is the CO of a great promotion prospect2Trapping recovery technology.Activated carbon adsorption CO2
Because of its cheap cost, high-adsorption-capacity, high adsorptive selectivity, excellent circular regeneration performance are solid material capture CO2In
One of most promising material.
103157436 A of patent documentation CN and 103193228 A of CN are individually disclosed with Semen Pini shell and melon-seed hull as original
Material, Semen Pini shell and melon-seed hull are crushed, and to obtain its powder, the particle mean size of the powder is 500～800 microns；By institute
Stating powder carries out charing process, to obtain carbonized material；The carbonized material is placed in potassium hydroxide solution carries out impregnation process；
The carbonated material after impregnation process is carried out into activation processing, to obtain the CO absorption2Semen Pini shell base and melon
Sub- scytoblastema activated carbon.Activated carbon obtained by the method its CO2Adsorbance is still good, but has the drawback that charing process and activation processing
Observable index is larger twice, and carbonized material is loaded down with trivial details with the impregnation process process of potassium hydroxide solution, and potassium hydroxide to make activator easily dirty
Dye environment.104310396 A of patent documentation CN are disclosed to add para-aminophenol after tripolycyanamide and formaldehyde reaction, are flowed back
Reaction 4, cool to room temperature, be subsequently adding the methanol solution of F127 or P123, respectively 100-120,130-160,170-190,
It is segmented at 210-230 and 240-260 DEG C and solidify respectively to obtain nitrogenous prepolymer, then carbonization, carbonized material mixes postactivated 0.5- with KOH
2.0h, most after Jing deionized waters cyclic washing to neutrality, obtain product after being dried.The method use a large amount of expensive and poisonous
Organic substance as predecessor, first carbonization again with KOH admixture activations, complex process, this advocate with current Green Chemistry using it is nontoxic,
The theory of harmless material is not inconsistent.
To sum up, develop a kind of CO of Cheap highly effective2Adsorbing material has important scientific value and good application prospect.
