Our AirPro activated carbon is manufactured by steam activation and is ideally suited to be used in many vapor phase applications to remove contaminants from air and gases, such as for solvent recovery, VOC (Volatile Organic Compound) adsorption in air treatment processes, purification of industrial and natural gas concentrations.
In this granular or pelleted form, the activated carbon is usually packed into a device (filter, vessel etc) where the contaminates in the gas stream will be processed for purification. In the adsorption process, molecules that are contaminated in the gas will be attracted and accumulate on the surface of the activated carbon. Not all activated carbons are suitable for vapor phase adsorption processes. Some of the physical characteristics that will affect the activated carbon’s working capacity, are the base material, pore size and distribution, particle size, activation temperature and activation method.
