Is Activated Carbon Hazardous?

Activated carbon is one of the most effective tools for dealing with VOC tire and malodorous gases. Activated carbon can adsorb the majority of the natural waste gas, when it’s filled with adsorption, it can be desorbed and regenerated and utilized consistently countless times.

A Renewable Resource

Activated carbon is an extremely efficient product for dealing with VOC exhaust gas and malodorous gases. Although lots of people state that activated carbon is difficult to use, some “ecological professionals” are demonizing triggered carbon, claiming that triggered carbon filtration is “out-of-date.”

Activated carbon can absorb a wide variety of biological waste gases, and when it’s saturated with adsorption, it could be regenerated and reused millions of times. Triggered carbon is still not a waste product; a minimum of the activated carbon can likewise be used as a gas, and its combustion heat is not lower than that of coal.

Activated Carbon Hazards

Wet activated carbon preferentially takes away oxygen from the air. In closed or partially closed vessels, oxygen depletion may reach hazardous levels. If it is necessary to enter a vessel containing activated carbon, samples are to be taken and certain work procedures are followed, including local requirements for potentially low-oxygen spaces.

For certain classes of chemicals, reaction or adsorption on the carbon surface is accompanied by release of a large amount of heat that may cause hot spots in the carbon bed. Impurities such as these organic sulfur compounds found in crude sulfate turpentine and other materials. Other classes of chemicals that may cause large thermal releases are ketones, aldehydes, and some organic acids. Adsorption of high vapor concentrations of organic compounds also can create hot spots. The heat released by adsorption or reaction on the surface of the carbon may pose a fire hazard.
