Description
Technical field
The invention belongs to activated carbon preparation field more particularly to a kind of metallic absorbent charcoal preparation methods.
Background technology
Activated carbon is a kind of porous solid carbonaceous of black.Early stage is by timber, xylocarp shell or beast bone etc. through carbonizing, activating system
, after use coal instead by crushing, molding or with uniform coal grain through carbonizing, activating production.Main component is carbon, and containing a small amount of
The elements such as oxygen, hydrogen, sulphur, nitrogen, chlorine.Activated carbon, since microcrystalline carbon is irregular alignment, has thin in structure between interconnection
Hole will produce carbon tissue defects in activation, therefore it is a kind of porous carbon, and bulk density is low, large specific surface area.
Activated carbon has extremely strong absorption property, is a kind of adsorbent that purposes is extremely wide, activated carbon is usually used in molten
Liquid carries out impurity absorption operation, certain impurity that can effectively in adsorbent solution using activated carbon, when activated carbon is completed to adsorb
It after operation, needs to be filtered it, activated carbon is filtered out from solution, this mode is more complicated, needs to carry out
Filter operation.
Invention content
The present invention overcomes the deficiencies in the prior art, provide a kind of metallic absorbent charcoal preparation method, keep activated carbon suitable
Profit is with metal adhesive together with, after activated carbon completes adsorption operations, usable magnet coordinate the prill inside it by its
It is sucked out, avoids filter operation.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of metallic absorbent charcoal preparation method, including it is following
Step：
(1) prill, coal raw materials, binder are sufficiently mixed, so that coal raw materials is passed through binder and is uniformly distributed in
Prill surface；
(2) prill for having mixed coal raw materials is put into liquor zinci chloridi, it is fully that metal is small using zinc chloride
Ball impregnates；
(3) by the prill after the completion of dipping be put into rotary furnace completely cut off air heating, heating time be 10min~
15min。
In a preferred embodiment of the present invention, the material of the prill described in step 1 is iron, cobalt, nickel.

℃。
In a preferred embodiment of the present invention, the binder described in step 1 is one or more of：Coal tar, again
Oil, molasses.
The invention solves the defect existing in the background technology, and the present invention has following advantageous effect：
(1) use metal as carrier, after activated carbon completes adsorption operations, magnet can be used to be sucked out, without into
Row filter operation is easy to use, quick；
(2) material of prill is iron, cobalt, nickel, to ensure can be sucked out by magnet；
(3) liquor zinci chloridi is used, is heated in high-temperature rotary furnace, it, can be by coal quality due to the dehydration of zinc chloride
Hydrogen and oxygen in raw material are mainly released as water vapor, to form the charcoal of cellular structure prosperity；
(4) heating temperature in rotary furnace be 600~700 DEG C, so as to smoothly by coal raw materials hydrogen and oxygen with
The form of vapor is released；
(5) use coal tar, heavy oil, molasses these three binders that can make when prill heats in rotary furnace
Coal raw materials are preferably bonded in prill surface, keep bonding more abundant, stable.
Specific implementation mode
With reference to specific embodiment, the present invention is further described, a kind of metallic absorbent charcoal preparation method, including with
Lower step：
(1) prill, coal raw materials, binder are sufficiently mixed, so that coal raw materials is passed through binder and is uniformly distributed in
Prill surface；
(2) prill for having mixed coal raw materials is put into liquor zinci chloridi, it is fully that metal is small using zinc chloride
Ball impregnates；
(3) by the prill after the completion of dipping be put into rotary furnace completely cut off air heating, heating time be 10min~
15min。
Wherein：The first step, coal raw materials are abundant by binder, are uniformly bonded in prill outer surface, ensure most
End form at activated carbon inside include prill always；Surface smear is had the prill of coal raw materials to put by second step
Enter in liquor zinci chloridi, since zinc chloride has dehydration, so the hydrogen and oxygen in coal raw materials can be sloughed；Third walks,
The prill for completing step 2 is put into rotary furnace and completely cuts off air heating, hydrogen and oxygen in coal raw materials is made mainly to be steamed with water
The form of gas is released.
Specifically, the material of the prill in step 1 is iron, cobalt, nickel, using iron, cobalt, nickel as the material of prill
Matter, to ensure that activated carbon can be smoothly sucked out by magnet after completing adsorption operations.
Specifically, the radius of the prill in step 1 is 0.5mm~0.8mm, and the radius of prill is within this range
The normal adsorption function of activated carbon is not interfered with.
Further, the prill quantity in step 1 is at least one, using one or more prills, is ensured
It can be smoothly sucked out using magnet.
