Abstract
The present invention relates to a kind of method that will inactivate regenerating active carbon, moisture content is dried for 30 80% inactivation activated carbon first；Then dried inactivation activated carbon heating is carbonized, obtains carbide；Carbon dioxide is finally passed through, carbide is activated, room temperature is then down to, packed, that is, the activated carbon after being activated.Present invention process is simple, and cost is low, can produce good social and economic benefit, the activated carbon of inactivation is after this method is handled, and adsorption activity is restored, close to the index before use.
Description
Technical field
The present invention relates to a kind of method that will inactivate regenerating active carbon, belong to technical field of fine.
Background technology
Activated carbon is that a kind of pore structure is very flourishing, specific surface area is very big, nonpoisonous and tasteless sorbing material, at present in city
Application in terms of city's sewage, advanced treatment of industrial waste water and Purification of Polluted Sources of Water is widely.But, due to activated carbon price
Height, the resources of production are more and more in short supply, if the activated carbon of adsorption saturation is discarded, and certainly will cause the wasting of resources, and can be to environment
Secondary pollution is caused, therefore, from the point of view of economical and environmentally friendly, the regeneration of activated carbon is significant.
The content of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of a kind of method that will inactivate regenerating active carbon.
Technical scheme
A kind of method that will inactivate regenerating active carbon, comprises the following steps：
(1) moisture content is dried for 30-80% inactivation activated carbon；
(2) dried inactivation activated carbon heating is carbonized, obtains carbide；
(3) carbon dioxide is passed through, carbide is activated, room temperature is then down to, packed, that is, the activity after being activated
Charcoal.
Further, in step (1), the drying temperature is 105-120 DEG C, and the time is 3-5h.
Further, in step (2), the carbonization temperature is 500-700 DEG C, and the time is 5-8h.
Further, in step (3), activation temperature is 700-800 DEG C, and the time is 6-8h.
Beneficial effects of the present invention：The activated carbon of inactivation is after this method is handled, and adsorption activity is restored, close to make
With preceding index.Present invention process is simple, and cost is low, can produce good social and economic benefit.
Embodiment
With reference to embodiment, the invention will be further described.
Embodiment 1
Moisture content is dried for 40% inactivation activated carbon, drying temperature is 120 DEG C, and the time is 4h；After drying
Inactivation activated carbon heating charing, carbonization temperature be 650 DEG C, the time is 7h, obtains carbide；Carbon dioxide is passed through, will
Carbide is activated, and activation temperature is 750 DEG C, and the time is 6h, is then down to room temperature, packaging, that is, the activated carbon after being activated.
Experiment is measured：Activated carbon loss late is 2.1%, methylenum careuleum adsorptive value 103mg/g (the methylenum careuleum absorption of new activated carbon
It is worth for 115mg/g).
Embodiment 2
Moisture content is dried for 70% inactivation activated carbon, drying temperature is 110 DEG C, and the time is 4h；After drying
Inactivation activated carbon heating charing, carbonization temperature be 600 DEG C, the time is 6h, obtains carbide；Carbon dioxide is passed through, will
Carbide is activated, and activation temperature is 750 DEG C, and the time is 7h, is then down to room temperature, packaging, that is, the activated carbon after being activated.
Experiment is measured：Activated carbon loss late is 1.5%, methylenum careuleum adsorptive value 105mg/g (the methylenum careuleum absorption of new activated carbon
It is worth for 115mg/g).
