Abstract
The invention relates to a shaddock peel activated carbon preparation method, comprising (1) washing the shaddock peels and removing the surface foreign materials and drying at 110-120 DEG C; (2) moving into a carbonization furnace for carbonizing 120-180 minutes at the carbonization temperature of 500-600 DEG C and in the oxygen isolation condition; (3) grinding, mixing with KOH powder and activating in the air flow at 700-800 DEG C and under 0.10-0.15 MPa; (4) activating the product and adding water to wash, dewatering, crushing and grading the solid material. The inventive method has simple operation, low cost, and environmental protection. Compared with the activated carbon prepared from other materials, the obtained activated carbon has more ducts, good adsorption, larger specific surface area and bigger pore volume.
Description
Technical field
The invention belongs to the preparation field of gac, particularly relate to a kind of preparation method of shaddock peel activated carbon.
Background technology
At present, Preparation of Activated Carbon is many to be raw material with timber, wood chip, Exocarpium cocois (Cocos nucifera L), shell etc., because reduce in the source of timber etc., shell is difficult to centralized collection, makes the raw material of preparation gac receive very big restriction, and price also is rise trend.What also have is the feedstock production gac with mud, plastics, but this method can cause environmental pollution.Adsorption efficiency with the gac of above feedstock production is not very desirable simultaneously.Therefore, adopt practicable novel process, seek new raw material and prepare gac and have important practical significance.Grapefruit is as a kind of evergreen undershrub, and fruit is delicious to have pharmaceutical use and output is huge, and domestic YO is greatly about about 2,000 ten thousand tons.If pericarp is not used and promptly causes wasting of resources contaminate environment again.Therefore manage to utilize the raw material of this kind of plant pericarp, it is turned waste into wealth as the preparation gac, significant.Because the shaddock leatherware has many crisscross passages, so itself just has the porous characteristic, be the good raw material of preparation gac, starting material are environmentally friendly thus, do not produce environmental pollution.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of shaddock peel activated carbon, and this preparation method is simple, and cost is low, and is environment friendly and pollution-free; The gained gac is compared with the gac of other feedstock production, and the duct is many, and absorption property is good, has that specific surface area is bigger, the more characteristics of pore volume.
The preparation method of a kind of shaddock peel activated carbon of the present invention comprises:
(1) the shaddock skin is cleaned cleaned except that surface irregularities, being dried to the moisture mass content at 110-120 ℃ is 5%-10%;
(2) with in the above-mentioned immigration carbide furnace, under carbonization temperature 500-600 ℃ and oxygen barrier condition carbonization 120-180 minute;
(3) with the above-mentioned 40-60 order that is ground to, the powder after the grinding mixed by mass ratio with the KOH powder in 1: 1,1: 2 or 1: 3, put into activation furnace, at temperature 700-800 ℃, and in the air-flow of pressure 0.10-0.15MPa activation 180-240 minute;
(4) above-mentioned activation products are added water washing, solid-liquid separation again adds water with solid separated and fully stirs postposition and went in the ultrasonic oscillator ultrasonic concussion 3-5 minute, wash then to PH be 6.5-7.0, solid materials dehydration crushing and classification promptly gets.
PH2-2.5, temperature 85-95 ℃ HCl solution washing is adopted in said step (4) washing.
Beneficial effect
(1) preparation method of the present invention is simple, and raw material sources extensively are easy to get, and belongs to utilization of waste material, reduce production costs, and environmentally safe;
(2) gained gac of the present invention is compared with the gac of other feedstock production, and the duct is many, and absorption property is good, has that specific surface area is bigger, the more characteristics of pore volume.
