Abstract
The invention discloses it is a kind of using jet coal prepare in big mesoporous activated carbon method, selected coal is single jet coal, using multi-component compound adhesive.The feed coal additive amount is 60%~80% according to total weight, and adhesive additive amount is 10%~25%, and water additive amount is 3%~10%.The processing such as raw material bonds through powder processed, press strip is granulated, charing and secondary charing, activation, are made big mesoporous activated carbon in jet coal.The present invention is not necessarily to Coal Blending Technology, using the active carbon of macropore prosperity in the preparation of single long flame coal, solves single long flame coal charing molding problem, while using multi-component compound adhesive, substantially improves production environment.
Description
Technical field
The invention belongs to active carbon preparation fields, more particularly to the method for big mesoporous activated carbon in a kind of preparation of jet coal.
Background technique
Active carbon has very important as a kind of widely applied environmental-protection adsorption material in industrial production and daily life
Effect.Ningxia is mainly raw using good too western coal as active carbon as the world's largest active carbon from coal production base
Produce raw material.Jet coal category low-disintegration coal kind, it is living in production column coal base with moisture, fugitive constituent and the high characteristic of tar content
Property charcoal when, powder safety processed is poor, carbonized material charing section be easy breakage.Currently, jet coal is mainly matched with active carbon from coal production
Material does not directly carry out production active carbon using single jet coal coal as raw material for deploying activated carbon pore size distribution.But long flame
Coal belong in macropore prosperity coal, with single jet coal be made have in greatly pore property high grade activated carbon, medicine, chemical industry,
There are other coal active carbons to be difficult to the important function substituted for the application in the fields such as oil refining.
Summary of the invention
In order to overcome the shortage of prior art, the present invention provides the method for big mesoporous activated carbon in a kind of preparation of jet coal, the party
Method is not necessarily to Coal Blending Technology, using the active carbon of macropore prosperity in the preparation of single long flame coal, to solve single long flame coal charing
Problem is formed, and improves the smell pollution problem of production plant area.
In order to achieve the above object, the invention adopts the following technical scheme:
A method of using jet coal prepare in big mesoporous activated carbon, it is characterised in that the preparation method comprises the following steps: utilizing jet coal coal
It crushes and is used as feed coal, then be equipped with adhesive and water, through the processing such as bonding, press strip, granulation, charing, secondary charing, activation, system
Obtain big mesoporous activated carbon in jet coal.
The feed coal additive amount is 60%~80% according to total weight, and adhesive additive amount is 10%~25%, water addition
Amount is 3%~10%.
The jet coal grinding particle size preferably 200 mesh.
The feed coal index is preferred: ash content 5%~10%, fugitive constituent 25%~35%, tar content 8%~15%, moisture is small
In 8%.
Described adhesive is multi-component compound high molecular polymer.
The charing process temperature is 100 DEG C~300 DEG C, and the time is 2h~4h, carbonization device using horizontal retort or
Low temperature distillation furnace.
The secondary charing process temperature is 400 DEG C~550 DEG C, and the time is 1h~2h, and secondary charing process equipment is sleeping
Formula retort.
The activating treatment temperature is 800 DEG C~950 DEG C, and activation time is 2h~3h.
The present invention uses multi-component compound high molecular polymer, has stability and lubricity good, the lesser feature of peculiar smell,
Compared with coal tar, the smell pollution of plant area can be effectively improved.In addition, press strip after adhesive and water blending, is made sketching charcoal appearance
Finish is preferable.
Compared with prior art, preparation method of the invention has the advantage that
1, the present invention prepares active carbon using single long flame coal, and macropore is flourishing in product, in medicine, chemical industry, oil refining etc.
Field, application value more have performance advantage compared with his coal.
2, the present invention is handled sketching charcoal using secondary charring process, effectively controls moisture, tar, the fugitive constituent of sketching charcoal
Content solves single long flame coal press strip and carbonizes problem easy to crack.
3, the present invention use multi-component compound adhesive, the adhesive be two or more high molecular polymers by a certain percentage
It configures, has many advantages, such as lubricity and stability, peculiar smell is small, can effectively solve the problems, such as the smell pollution of production plant area.
