Abstract
A dolomite modified activated carbon desulfurization agent is prepared from the following raw materials: by weight, 100-120 parts of activated carbon, 20-23 parts of dolomite, 10-12 parts of montmorillonite, 3-4 parts of citric acid, 4-5 parts of polyacrylonitrile microsphere, 8-10 parts of modified attapulgite and a proper amount of water. The dolomite modified activated carbon desulfurization agent uses the dolomite and the montmorillonite, is dried by calcining and spraying, and has good adsorption and desulfurization performances; by addition of the polyacrylonitrile microsphere, the dolomite modified activated carbon desulfurization agent has an increased strength and is not easy to collapse; and the dolomite modified activated carbon desulfurization agent has the advantages of easily obtained raw materials, simple process and low cost, is suitable for industrial production, may not produce harmful materials, and has a good application prospect.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of dolomite modified activated carbon sorbent and preparation method thereof.
Background technology
Along with scientific and technological development, the progressively construction of modernization industry, various chemicals are exploited, and have brought facility to people's life, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face.
Current airborne pollutant is mainly the toxic and harmful produced in the gas that produces of industrial fuel burning, vehicle exhaust, production.It is mainly to contain a large amount of noxious materials in the sewage of industrial production discharge that water pollutes, and also has the sewage in people's life to produce a lot of harmful substances.Also have and many times need to remove toxin in people life, such as air conditioning filter has a lot of bacteriums, toxin on the net, newly-decorated has the harmful substance such as formaldehyde, all needs to remove toxin.All remove at present toxin and often use adsorbent, mainly contain silica gel, activated alumina, active carbon, molecular sieve etc., the sorbing material of developing for certain compositional selecting absorption in addition in addition.But the most adsorption capacity of these adsorbents is limited, need to study different adsorbents for different requirements, bring into play best effect.Simultaneously, find new raw material, to strengthen adsorption effect, cost-saving.
Summary of the invention
The object of the present invention is to provide a kind of dolomite modified activated carbon sorbent and preparation method thereof.
Technical scheme of the present invention is as follows:
A kind of dolomite modified activated carbon sorbent is characterized in that being made by the raw material of following weight portion: active carbon 100-120, dolomite 20-23, montmorillonite 10-12, citric acid 3-4, polyacrylonitrile microballoon 4-5, attapulgite modified 8-10, water are appropriate; The described attapulgite modified raw material by following weight portion is made: attapulgite 120-130, sodium carbonate 3-4, bauxite 5-6, vanadium boride 1-2, jade powder 3-4, ferrous sulfate 1-2, titanium sulfate 14-18, active carbon 12-14, medical stone 2-3, lanthana 1-2, chromium oxide 3-4, morpholine 1-2, water are appropriate; Attapulgite, bauxite, jade powder, active carbon are sent in calcining furnace, and under 850-870 ℃, calcining 4-5 hour, take out, putting into suitable quantity of water grinds again, regulating the lapping liquid pH value is 4-5, grinds 1-2 hour, obtains 100-150 order slurry, regulate again the lapping liquid pH value for neutral, add other residual components, continue to grind, obtain 200-300 order slurry, spray-drying, obtain.The preparation method of described dolomite modified activated carbon sorbent, it is characterized in that comprising the following steps: dolomite, montmorillonite are sent in calcining furnace, in 820-850 ℃ of calcining furnace, calcining 4-5 hour, take out, and together with citric acid, polyacrylonitrile microballoon, active carbon, puts into suitable quantity of water, be heated to 80-90 ℃, grind 2-3 hour, obtain 200-300 order slurry, spray-drying, mix with attapulgite modified, obtain.
Divide the beneficial effect of the invention
