Abstract
The present invention relates to a coal based active carbon forming agent which belongs to the manufacturing field of coal based active carbon and overcomes the defect of using coal tar as a forming agent. The forming agent is characterized in that the forming agent is prepared by respectively dissolving industrial chemicals, such as acrylamide, triethanolamine, starch, potassium hydroxide, ammonium sulfate, borax, ammonium persulfate, etc. in a certain amount of water to be mixed and stirred. The coal based active carbon forming agent of the present invention, which replaces coal tar, overcomes the defects that the coal tar has serious pollution, high cost, difficulties of heat preservation operation, transportation and storage, etc. Contrarily, the coal based active carbon forming agent of the present invention has the advantages of low pollution, low price, easy purchase, transportation and storage, low cost, etc. Simultaneously, the performance index or the quality index of coal based active carbon is kept or improved. The coal based active carbon forming agent with strong adaptability is applied to all fields of formed coal based active carbon preparation.
Description
Technical field the present invention relates to a kind of coal quality active carbon forming agent, belongs to coal mass active carbon and makes the field, solves the drawback of using coal tar to make forming agent.
Background technology the present invention is " coal quality active carbon forming agent "
With coal is feedstock production typing gac, dust coal must be made creme, and compression moulding is then made product through charing, activating process again.
Before this, dust coal being made creme, is to form with the coal tar mix.The weight ratio of coal dust and coal tar preparation is roughly 2: 1.Use coal tar that following shortcoming is arranged:
1, usage quantity is big and price is high.
2, pollute greatly.Coal tar is mixed with that harmful, toxic substance is volatilized to come out in mix creme and carbonization process, environment is caused severe contamination and abominable smell.
3, coal tar must become creme and compression moulding by mix under steam is uninterruptedly heated condition.
" coal quality active carbon forming agent " of the present invention overcome above-mentioned shortcoming:
1, saves a large amount of tar resources, make it to be used for prior field.
2, reduce contamination phenomenon greatly, or polluted slightly odorlessness.
3, operation at normal temperatures, simple, convenient.
4, inexpensive, easily purchase, easily transportation, easily keeping.Its component is 10% with interior micro-industrial chemicals, and all the other are the water more than 90%.
5, keep or improve the performance index or the quality index of coal mass active carbon.
Summary of the invention 1, coal quality active carbon forming agent are achieved in that it is that main raw material is dissolved in respectively in the quantitative water with acrylamide, trolamine, starch, potassium hydroxide, ammonium sulfate, borax, ammonium persulphate, form through mixing, stirring.
2, prescription is: acrylamide: 2.0-10%
Trolamine: 0.3-1.5%
Over cure hydramine: 0.3-1.5%
Starch: 3.5-10%
Potassium hydroxide: 0.5-2%
Sulfuric acid amine: 0-1%
Borax: 0-0.1%
Water: surplus
3, blending process is:
(1) acrylamide, trolamine, starch, ammonium sulfate and borax are dissolved in 50% the water of water consumption, are mixed with solution 1;
(2) ammonium persulphate is dissolved in 25% the water of water consumption, is mixed with solution 2;
(3) potassium hydroxide is dissolved in 25% the water of water consumption, is mixed with solution 3;
(4) solution 2 is added in the solution 1 under constantly stirring, stirred about 30 minutes, add solution 3 again, stirred about 30 minutes,, be coal quality active carbon forming agent to becoming even sticking liquid.
We are respectively with Datong District's weakly caking coal, Taixi anthracite, Heilungkiang long-flame coal, utilize this invention achievement to produce coal mass active carbon, its finished product detects through China Shanxi Xinhua Chemical Plant authority detection department, and its every index all meets or exceeds the coal mass active carbon index with the coal tar moulding.
Embodiment embodiment 1:
When 1, being applied to the high coal of metamorphic grade and preparing gac, the coal quality active carbon forming agent prescription is:
Acrylamide: 4.4%
Trolamine: 0.6%
Starch: 3.6%
Potassium hydroxide: 0.6%
Over cure hydramine: 0.6%
Water: surplus
2, blending process:
With summary of the invention 3
Embodiment 2:
When 1, being applied to metamorphic grade coal low or that fugitive constituent is high and preparing gac, the prescription of coal quality active carbon forming agent is:
Acrylamide: 3%
Trolamine: 0.45%
Starch: 7.2%
Potassium hydroxide: 1.2%
Over cure hydramine: 0.45%
Borax: 0.01%
Ammonium sulfate: 1%
Water: surplus
2, blending process:
With summary of the invention 3.
