Abstract
A kind of method utilizing pomelo peel, waste of flax, walnut shell to prepare active carbon, comprise choose pomelo peel, waste of flax, walnut shell mix in proportion, mixture after drying is pulverized to obtain raw material, by feed particles and activator mix even mixed material, add water retting, material after dipping is put into micro-wave oven and carries out carbonization-activation, pickling and washing successively, oven dry, drying material is ground, and adopt the sieve of different meshes to carry out screening acquisition three grades of fineness active carbons, they are mixed to form final products in proportion.Active carbon prepared by the present invention has good absorption property and service life.
Description
Technical field
The application relates to a kind of preparation method of active carbon, particularly relates to a kind of method utilizing pomelo peel, waste of flax, walnut shell to prepare active carbon.
Background technology
Active carbon, owing to having flourishing internal pore structure, therefore becomes a kind of extremely important adsorbent, is widely used in many fields such as water treatment, environmental protection, agricultural.The raw material preparing active carbon is a lot, and the plant materials such as existing timber, husk, crop material, also have coal, petroleum coke, rubber etc.In energy crisis and environmental problem day by day serious today, utilize agriculture and forestry organic waste material that is cheap, abundance to prepare active carbon and receive increasing concern.But existing technique is usually all more single when selecting agriculture and forestry organic waste material raw material, the performance of therefore prepared active carbon is comparatively uneven, is unfavorable for the Appropriate application of agriculture and forestry organic waste material.
Summary of the invention
The present invention aims to provide a kind of method for preparation of active carbon, and it adopts multiple agriculture and forestry organic waste material to be mixed to form raw material in proportion, particularly, comprises the steps:
(1) choose pomelo peel, waste of flax, walnut shell mix in proportion, dry 18 hours at the temperature of 115 degrees Celsius;
(2) mixture after step 1 being dried is crushed to particle diameter about 1.6-1.8mm, obtains feed particles;
(3) feed particles in step 2 is mixed in proportion to obtain mixed material according to potassium hydroxide and potash, add the water of 50 degrees Celsius with weight such as mixed materials, flood 18 hours;
(4) material after the dipping in step 3 is put into micro-wave oven, preferably, carbonization-activation 7 minutes under the microwave irradiation power of 400-450W.
(5) hydrochloric acid of 1.5 moles often liter is adopted to boil 40 minutes under 85 degrees Celsius material after the activation in step 4, more neutral in rinsing in pure water, then dry 10 hours under 130 degrees Celsius.
(6) drying material in step 5 is ground, and adopt the sieve of different meshes to carry out screening acquisition three grades of fineness active carbons, they are mixed to form final products in proportion.
Preferably, choose pomelo peel, waste of flax, walnut shell mix in 1:2:1 or 1:2:2 ratio.
Preferably, the part by weight of step 3 Raw particle and potassium hydroxide and potash is 1:2:1 or 1:2:2.
Preferably, in step 6, different meshes is 160 orders, 200 orders and 240 orders, and three grades of fineness activated carbon weight are than being 1:3:2.
Preferably, in step 6, different meshes is 150 orders, 200 orders and 250 orders, and three grades of fineness activated carbon weight are than being 1:3:1.
Because the present invention adopts agriculture and forestry organic waste material as raw material, reduce the manufacturing cost of active carbon; And be mixed to form raw material in proportion owing to present invention employs multiple different agriculture and forestry organic waste material, take full advantage of the feature that different agriculture and forestry organic waste material possesses the compounds contents such as different lignin, cellulose, hemicellulose, different agriculture and forestry organic waste material is learnt from other's strong points to offset one's weaknesses mutually, enhance the utilization ratio of agriculture and forestry organic waste material, improve the performance of prepared active carbon.
