Description
Technical field
The present invention relates to environmental pollutant adsorption treatment technical field, be specifically related to gac preparation and the forming method of the activation of a kind of KOH solid.
Background technology
Gac is the product utilizing agricultural byproducts, coal and the heavy crudes such as charcoal, wood chip, shell to obtain through carbonization-activation for raw material, and nearly all carbonaceous material can be used for preparing gac.Gac, as the most ancient most important good porosity sorbing material, owing to possessing highly developed gap structure and huge inner ratio surface area, stable performance, the feature such as can to regenerate, be widely used in the fields such as chemical industry, environmental protection, military chemistry protection.
At present for the preparation of coal mainly bituminous coal, hard coal, the brown coal etc. of gac.Rich coal resources in China, become and produce coal mass active carbon big country, conventional is hard coal and non-caking coal, weakly caking coal, but the gac insufficient quality produced, kind is single.Active carbon with high specific surface area, owing to having abundanter internal pore structure and superpower adsorptive power, has higher value in application aspect than normal activated carbon.Therefore it is significant with coal to be that main raw material obtains active carbon with high specific surface area.
Based on selected raw material and purposes, the method preparing gac is mainly divided into physical activation method and chemical activation method two kinds, in actual application, requires to select suitable activation method according to required Properties of Activated Carbon.Physical activation method is at high temperature reacted with the oxidizing gas such as water vapour, carbonic acid gas or air and Carbon Materials by raw material, makes unordered charcoal partial oxidation etching in Carbon Materials, form flourishing microvoid structure at material internal.Carbonization temperature is generally at 600 DEG C, and activation temperature is at 800-900 DEG C
[1].Chemical activation method is by raw material and pharmaceutical chemicals hybrid infusion for some time by a certain percentage, and charing and activation one step complete.Conventional chemical activating agent has ZnCl

3pO
4, KOH etc.
[2].ZnCl

Summary of the invention
The object of the invention is for the deficiencies in the prior art, the gac preparation providing a kind of KOH solid to activate and forming method.
The technical solution adopted for the present invention to solve the technical problems comprises the steps:
Step 1, by quick for KOH solid grind into powder, add gac precursor by a certain percentage after having ground, then Quick uniform is mixed to form mixture;
Step 2, mixture is put into atmosphere furnace, at N rapidly
2under protection, be warming up to 700-1000 DEG C with the temperature rise rate of 5-15 DEG C/min, activation 30-120min, through washing, oven dry after cooling, obtain KOH activating activities carbon powder;
Step 3, sodium metaaluminate, water glass, KOH are mixed to form tackiness agent by a certain percentage, until KOH deliquescence completely after, then add KOH activating activities carbon powder, tackiness agent and KOH activating activities carbon powder with mass ratio 1:4 mixing kneading, extrusion molding;
Step 4, shaping particle are dried under 105 DEG C of conditions, obtain shaped granule gac.
Described gac precursor is all kinds of coal dust, comprises pulverized anthracite, bituminous coal, brown coal etc.
KOH solid is chemical activating agent, when mixing with gac precursor, for preventing KOH solid deliquescence, needs clay into power fast and put into atmosphere furnace, and the mass ratio of KOH and coal dust is (1:5)-(10:1).
Tackiness agent described in moulding process is the basic material of synthesis of molecular sieve, and the molar mass of the sodium metaaluminate in concrete tackiness agent: water glass: KOH is than being 1:(0.5-5): (0.5-4).
Compared with prior art, the invention has the advantages that:
The present invention directly with KOH solid for activator, by regulating the proportion adjustment activation effect of KOH solid and coal dust.Compared with KOH solution, do not need long-time dipping, shorten preparation time and under the same terms activation effect better; Compared with carbonic acid gas or steam activation, activation temperature is low, save energy.
Moulding process uses sodium metaaluminate, water glass, KOH to be tackiness agent, is the basic material of synthesis of molecular sieve.Ultimate compression strength and the wear resistance of shaping rear particle are all higher.
