Abstract
The present invention is a kind of method of high abrasion resistance strength preparing absorbent charcoal with petroleum coke, its technical process includes milling, kneading and compacting, charing, activation, screening packaging, wherein, charcoal turns to secondary charing, coal tar pitch is incorporated during kneading and compacting, activation and carbonization time and other process conditions are all adjusted.The present invention is compared with the active carbon that traditional technology produces, and in the case where carbon tetrachloride adsorbance > 73% (W), bulk density reaches 510-520g/L, in terms of intensity also superior to the active carbon of traditional technology production.
Description
Technical field
The present invention relates to coal processing fields, are a kind of production methods of active carbon, especially a kind of high abrasion resistance strength stone
The method that oil coke prepares active carbon.
Background technique
Active carbon is a kind of large specific surface area, and the porosity carbonaceous material of strong adsorption, absorption property is stronger, internal holes
Gap rate is more flourishing, and heap weight is then lower, therefore, heap weight and the conflict that absorption property is in Activated Carbon Production, by existing work
The production technology of property charcoal, in Penetrating curve > 73%, heap weight values are generally in 470~490g/L.
Summary of the invention
When being greater than 73% the object of the present invention is to provide a kind of four chlorination charcoal adsorptive values, stone of the bulk density in 510g/L or more
The method that oil coke prepares active carbon.
High bulk density active carbon when in use, can increase the additional amount of active carbon, to improve in identical space
Adsorbance.
The purpose of the present invention is realized by following proposal: the method for preparing absorbent charcoal with petroleum coke, using raw material petroleum coke as raw material,
Its technical process includes milling, kneading and compacting, charing, activation, screening packaging, wherein kneading and compacting is supplying 10~30% (W)
Coal tar pitch, mixing time are 20~50 minutes, 150~220kg/cm of briquetting pressure2, above-mentioned carbonization process is carried out in two steps, and one
Secondary condition of carbonization are as follows: 250~380 DEG C of end flue temperature, 150~250 DEG C of temperature in furnace, furnace tail temperature is less than 100 DEG C, one
The outlet of secondary carbonized material carries out water spray processing, secondary condition of carbonization are as follows: and 550~650 DEG C of end flue temperature, temperature 350 in furnace~
480 DEG C, furnace tail temperature is less than 200 DEG C, the process conditions of above-mentioned active process are as follows: and 880~950 DEG C of activation temperature, furnace pressure 60~
100Pa, 2.0~3.0T/h of quantity of steam, the discharge time 30~60 minutes.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
Embodiment:
Technical process are as follows: water coal tar coal tar pitch
Raw material petroleum coke → milling → kneading and compacting → primary charing → secondary charing → activation → screening packaging → finished product
Wherein, raw material selects Taixi anthracite, breaks to 6-16 mesh, heap is great in 740g/L, fugitive constituent 6.5-9.0%, ash
Part < 3%, moisture content < 4% just can be used after fine purifiation；For mixed deduction type in addition to coal tar is added, it is still necessary to 10-30% is added
(W) coal tar pitch, molding mixing time 20-50 minutes or more, briquetting pressure 150-220kg/cm2, using charcoal chemical industry twice
Skill, the primary discharge port that carbonizes spray water to carbonized material, and the hot carbon granules that makes to come out of the stove acutely is shunk, and achieve the purpose that mention great bulk weight, a charcoal
Change condition are as follows: 250-380 DEG C of end flue temperature, 150-250 DEG C of temperature in furnace, 100 DEG C of < of furnace tail temperature, secondary condition of carbonization
Are as follows: 550-650 DEG C of end flue temperature, 350-480 DEG C of temperature in furnace, 200 DEG C of < of furnace tail temperature, activating process condition are as follows: activation temperature
880-950 DEG C, furnace pressure 60-100Pa of degree, quantity of steam: 2.0-3.0T/h, discharge time 30-60 minute.With method of the invention
300 tons of qualified products are produced, and are placeed goods on trial sale to foreign countries, are got a good review.
