Abstract
The invention provides an activated carbon white powder preparation technology. The activated carbon white powder preparation technology comprises the following specific steps of: crushing a bamboo raw material, and sieving the crushed bamboo raw material by using a sieve with 10-100 meshes; soaking the sieved bamboo in a 30%-50% phosphoric acid solution, and preserving for 3 to 5 days under a sealing condition, wherein the weight ratio of the bamboo to the 30%-50% phosphoric acid solution is 1:1; filtering the mixed liquid to obtain the bamboo soaked by phosphoric acid, and then drying the bamboo at 110 DEG C for 1 day; activating the dried bamboo at 900-1100 DEG C in a CO2 atmosphere so as to obtain black activated carbon; and uniformly mixing the black activated carbon, calcium chloride, zinc chloride and potassium carbonate, and activating the mixture at 900-1100 DEG C in a CO2 atmosphere to obtain the white activated carbonate. The preparation technology provided by the invention is simple and high in efficiency; and the prepared activated carbon white powder has strong adsorption capacity and can serve as a wall material for interior decoration.
Description
[technical field]
The present invention relates to a kind of preparation technology of gac white powder.
[background technology]
The main raw material of gac almost can be all organic materialss that are rich in carbon, such as coal, timber, shell, coconut husk, nut-shell etc.These carbonaceous materials are converted into gac by pyrolysis under high temperature and certain pressure in activation furnace.In this reactivation process, huge surface-area and complicated pore texture form gradually, and so-called adsorption process just in these holes and the surface carry out, the effect that the size of gac mesoporosity has selection to adsorb to adsorbate, this is because macromole can not enter than the cause in the little gac aperture of its hole.
In adsorption process, the difference of reactive force between gac molecule and the contaminant molecule can be divided into absorption two large classes; Physical adsorption and chemisorption (claiming again activated adsorption).In adsorption process, when being Van der Waals force (or electrostatic attraction), the reactive force between gac molecule and the contaminant molecule is called physical adsorption; When being chemical bond, the reactive force between gac molecule and the contaminant molecule is called chemisorption.The adsorption strength of physical adsorption is main relevant with the physical properties of gac, and is substantially irrelevant with the chemical property of gac.Since Van der Waals force a little less than, little to the structure influence of contaminant molecule, this power is the same with intermolecular cohesion, so can analogize to coacervation to physical adsorption.
Because chemical bond is strong, and is larger to the structure influence of contaminant molecule, so can regard chemisorption as chemical reaction, is the result of chemical action between pollutent and gac.Chemisorption generally comprises electron pair to be shared or transfer transport, rather than simple perturbation or weak polarized action, is irreversible chemical reaction process.The fundamental difference of physical adsorption and chemisorption is to produce the reactive force of adsorption bond.
Gac white powder outward appearance is white fine-powder shape, and nontoxic, tasteless, it is large to have specific surface area, high adsorption capacity, is applicable to interior decoration, purifying air absorption peculiar smell.Also can be used for refining sugar, the purification industry of the water quality such as pharmacy, beverage, drinks, the decolouring of organism solvent, refining, purification and sewage disposal aspect also are widely used.
