Carbotecnia coal reactivation

How can you save up to 40% on the cost of replacing activated carbon?

A practice that few speak of in Mexico, with which it is possible to save up to 40% of the cost per kilo of coal and is also friendly to the environment, is: the reactivation of coal. The main benefits of depleted coal reactivation are:


The price per kilogram of reactivated coal is roughly half the cost of virgin coal.


The spent coal practically recovers its initial capacity, after being reactivated.


It prevents spent coal residues from going to unsuitable places, which can cause damage to the environment and health.


By reactivating spent coal, you virtually eliminate the costs and liability of disposal.

What other environmental benefits do we generate by reactivating coal?

➩ Contaminant residues are minimized and the amount of CO2 associated with the production, supply and use of virgin activated carbon.

➩ Helps prevent CAG from taking up landfill space.

➩ Avoid leachate or polluting emissions from spent CAG.

How is a coal reactivated?

It is possible to reactivate spent granular carbons by various methods, among which the most common is thermal (in a rotary kiln at 800 ° C and in an atmosphere saturated with water vapor).

The coal obtained it usually recovers all its original capacity. With the revival, the need to dispose of spent coal (as industrial waste) is avoided and Up to 50% can be saved in the replacement of activated carbon - reactivation

After the adsorption capacity of an activated carbon has been exhausted it is fully recyclable, the adsorbed organics are destroyed and the reactivated carbon can be safely and cost-effectively recycled for continued use.

The following image exemplifies step 2 of the reactivation process:

The reactivation process takes the following steps:


Thermal phase.

Spent activated carbon is heated in oxygen-deprived furnaces using steam as a selective oxidant.

Desorption of pollutants.

The adsorbed organic compounds are volatilized and pyrolyzed to carbon dioxide.


The volatilized organic materials are destroyed in the post-combustion of the kiln.

Thermal scrubbing.

Acid gases are removed by means of a thermal scrubber.

Restoration of adsorption capacity.

The high temperature reaction with steam serves to restore the adsorption capacity of the activated carbon and control over carbonization.

➩ We have been reactivating and manufacturing coconut shell charcoal for more than 25 years.

➩ We have the permits before SEMADES for its reactivation, we deliver all the documents that the process implies, in addition to a quality certificate.

➩ We also offer a service for the collection, storage and disposal of spent activated carbons.

If you use activated carbon for any of these applications: it can be reactivated.

Water purification.

Activated carbon from purifiers and industrial water treatment plants.

Treatment of beverages

Activated charcoal that is used as a purifier to reduce certain odor, flavor and color molecules in Tequila, Rum, Mezcal and other beverages.

Organic gas purification

Granular and pellet activated carbons are used to reduce industrial and commercial gas pollutants.

Manufacture process.

Activated carbon that is classified as: "Special handling waste" and that is used in a wide variety of industrial processes.
