Description
Technical field
The present invention relates to catalyst technical fields, more particularly, to one kind using useless cocoanut active charcoal as raw material, by a system
The method that catalyst is made in the processing of row.
Background technology
Absorbent charcoal material is that have the characteristics that large specific surface area by the amorphous carbon obtained by working process, to gas, molten
Inorganic or organic substance and colloidal solid in liquid etc. have good adsorption capacity.Activated carbon has wooden activity by material point
Charcoal, active fruit shell carbon, coaly activated carbon, petroleum-type activated carbon, regenerated carbon, mineral raw material activated carbon.Activated carbon is as a kind of
Environmentally friendly adsorbent, have stronger adsorptivity and catalytic performance, acid and alkali-resistance, heat-resisting, not soluble in water and organic solvent, easily
The advantages that regeneration, therefore activated carbon increasingly receives attention in water process, but since there is also some disadvantages for activated carbon, such as
The features such as ash content height, Kong Rong little, poor adsorptive selectivity, makes it in addition some of its surface functional group and electrochemical properties limit
It is limited to the Adsorption effect of pollutant, it much can not meet the demand of domestic and international market.Therefore Recent study activated carbon
Loading heavy metal ion catalyst becomes the new hot spot in the field for degradable organic pollutant.But prepare activated-carbon catalyst mistake
There is also many problems, such as complex process in journey, and condition is harsh, of high cost, be easy to cause secondary pollution etc., these factors are equal
Limit large-scale application of the activated-carbon catalyst in actual waste water processing.
Invention content
In view of the above-mentioned problems existing in the prior art, the present patent application provides a kind of activated-carbon catalyst and its preparation side
Method.The present invention has and has a wide range of application, and preparation process is relatively easy, and non-secondary pollution can be recycled, feature at low cost.
Technical scheme is as follows：
A kind of preparation method of activated carbon catalyst, the preparation method include the following steps：
(1) useless cocos active carbon is settled 2~3 times repeatedly in clear water, carries out clear water cleaning；
(2) by the useless cocos active carbon after clear water cleans in saturated aqueous sodium carbonate ultrasonic disperse 0.5~
1.2h is filtered, and collects filter residue；
(3) it will be sent in rotary kiln by auger by the useless cocos active carbon of step (2) processing, program heating-cooling,
It is discharged in special collection vessel finally by auger, pretreated useless cocos active carbon is made；
(4) it will be added in 10~15% salpeter solution by pretreated useless cocoanut active charcoal, ultrasonic reaction 0.5~
The useless cocos active carbon of acidification is made in 1.2h；
(5) heavy metallic salt prepared simultaneously containing copper ion, nickel ion, iron ion, cobalt ions, cerium ion, manganese ion is molten
Liquid；
(6) cocoanut active charcoal of acidification is poured into the heavy metallic salt solution configured, seal, on Oscillation device with
It after 15~20h of speed Oscillation of 10 turns/min, removes, filters, collect filter residue, recycle filtrate；
(7) filter residue for collecting step (6), is sent to by auger in rotary kiln, start program heating-cooling passes through strand
Dragon is discharged in special collection vessel, and the activated-carbon catalyst is made.
The process of program heating-cooling described in step (3) is：700 DEG C are heated to the heating rate of 50 DEG C/h, stops rising
Temperature keeps the temperature 2~3h, is down to room temperature again with the rate of temperature fall of 50 DEG C/h later.
The group of heavy metallic salt solution described in step (5) is divided into：A concentration of 40~60g/L of copper nitrate, nickel nitrate are a concentration of
40~60g/L, iron nitrate concentration are 60~80g/L, a concentration of 15~25g/L of cobalt nitrate, a concentration of 8~18g/L of cerous nitrate, nitre
Sour a concentration of 5~12g/L of manganese.
The method of program heating-cooling described in step (7) is：300 DEG C are heated to the heating rate of 75 DEG C/h, stops rising
Temperature keeps the temperature 1~1.5h, then with the heating rate of 50 DEG C/h, when rising to 500 DEG C, stops heating, keeps the temperature 1~1.5h, then with 100
DEG C/heating rate of h rises to 700 DEG C, after keeping the temperature 2~3h, room temperature is finally down to the rate of temperature fall of 50 DEG C/h.
The present invention is beneficial to be had technical effect that：
The specific surface area for the cocoanut active charcoal that the present invention uses is 1250-1600m2/ g, appearance and size are φ 1*1.5mm,
Micropore size 10A-30A again has large specific surface area, and aperture is moderate, and the benefit being evenly distributed contributes to heavy metallic oxide
Uniform load, it is more efficient to make in catalytic electrolysis waste water.
It is that the heavy metallic oxide of load can be made more to have a sense of hierarchy that the present invention, which selects the benefit of ladder-elevating temperature, because different
The decomposition temperature of nitrate be different, and if the purpose that controls at 700 DEG C for outlet temperature is because can be made more than 700 DEG C
The carbonization of itself of Viability charcoal, and temperature is too low, and degree of sintering can be caused inadequate, the heavy metal oxidation loaded in use
Object is easy to fall off, and influences service life.The purpose to be cooled down using ladder is in order to prevent during fast cooling, and reduction was subcooled
Thermal phenomenon, reduction make the risk that the catalyst strength of preparation is deteriorated.
Conventional activated carbon supported heavy metal catalyst service life is 5-10 times, and is urged according to prepared by our technique
The service life of agent is 40-50 times, substantially increases service life, reduces cost.What in addition we used is coconut activated
Charcoal is waste active carbon, has been achieved the purpose that precious with useless system.
Using activated carbon as carrier, its porous and large specific surface area characteristic is utilized, it is organic during electrocatalytic oxidation
Waste water is first adsorbed, then is contacted with the heavy metallic oxide loaded, and these heavy metallic oxides can greatly improve electricity and urge
Change the rate that hydroxyl radical free radical is generated in oxidation process, to greatly improve the degradation speed of organic wastewater.
Specific implementation mode
With reference to embodiment, the present invention is specifically described.
