Chemviron Carbon Ltd

About

Activated Carbon manufacturers and suppliers with offices and/or reactivation plants in Belgium, France, Germany, Denmark, Sweden and the UK. In addition to activated carbon, Chemviron Carbon supplies fixed and mobile adsorption units (carbon filters) for liquid and gas phase applications. We recently expanded our reactivation capacity in Europe making us the largest reactivator of activated carbon in the World. All manufacturing sites are ISO9001 and ISO14001 accredited.

Activated carbon - a panacea in aerosol propellants

Since the demise of CFCs, the majority of aerosol propellants have been based on light hydrocarbon components e.g. propane, butane and iso-butane. Although combinations of these materials have suitable vapour pressure characteristics, they are Volatile Organic Compounds (VOCs) which contribute to low level ozone and global warming effects. Hydrocarbons are based on oil and continue to be geo-politically sensitive.

Disadvantages of hydrocarbon propellants include:

  • Highly flammable

  • Responsible for many incidents in filling facilities and during their transportation

  • Residual hydrocarbons in used canisters is a problem for recycling

  • Volatile Substance Abuse - several deaths per year in the UK are associated with inhalation of aerosol propellants.

  • Hydrocarbon-based propellant during designed use may contribute to problems related to Indoor Air Quality.


  • Compressed gas propellants, e.g. carbon dioxide and nitrogen, are low-cost, low-toxicity, non-flammable, inert materials ideally suited to the environment. However, when deployed in aerosol canisters the pressure in the container depletes rapidly as the contents are used and the rate of discharge is reduced. To alleviate these problems, Chemviron Carbon has developed gas storage and aerosol dispensing systems based upon adsorbed permanent gases.

    Chemviron Carbon has developed a range of products under the CellcarbTM name. These products can be adapted for use in a range of aerosol applications:

  • Foghorns

  • Dusters

  • Oxygen Cans

  • Traditional Aerosols - hairspray, deodorant, shave gel, insecticide, polish, air fresheners etc.

  • Beverage carbonation and delivery


  • Benefits of employing carbon dioxide with selected activated carbon:

  • C/CO2 is non-flammable

  • C/CO2 is non-toxic and both the carbon and CO2 are food quality compliant. There is little scope for substance abuse

  • C/CO2 is environmentally benign1

  • The working pressure of a given system can be designed based upon selection of suitable carbon and carbon dioxide quantities.

  • 1Although CO2 is a greenhouse gas, its deployment in an aerosol canister has a neutral effect in terms of global warming because the gas is recovered as a by-product from a number of industrial processes and would otherwise be released to air. For the European market, sequestration of the gas, together with replacement of the hydrocarbon gases, is equivalent to removing 5 million tonnes/year of carbon dioxide from the atmosphere (akin to 1,700,000 mid-sized cars). CO2 has no propensity to deplete stratospheric ozone.
