The present invention aims to provide an activated carbon for adsorbing a molecular polar substance with excellent adsorption property to a molecular polar substance and regeneratability. The present invention provides an activated carbon for adsorbing a molecular polar substance obtained by an alkali activation method, wherein the activated carbon has an acidic functional group in an amount of 2.1 meq/g or more, a basic functional group in an amount of more than 0 to 0.6 meq/g, and a specific surface area of 1000 to 4000 m.sup.2/g.

A composition for disinfecting air including a biochar combined with a biocide. According to an embodiment, the biocide is mechanically active, i.e. it destroys, prevents the action of the pathogenic microorganism by mechanical action and without chemical action. Another aspect relates to a device for disinfecting air including the composition and a support. Another aspect relates to the use of the composition for disinfecting air or a disinfection device for reducing the amount of pathogenic microorganisms in an air flow. The present disclosure relates to the field of air disinfection. In an embodiment, it can be applied to the treatment of air for the purpose of suppressing pathogenic microorganisms such as viruses, bacteria, fungi. An embodiment can be applied in an air treatment device for treating enclosed spaces such as an entire structure or specific spaces in a building or any transport vehicle.

The formation of sterilization tubes by plates with parts that match in whole or in part, that when assembled together form ducts, passages, channels, or tubes in a mass or block of heat resistant material. The size of the block may be reduced by forming the ducts as curved passages or tubes that will keep or increase the length of the tube while keeping the same or more exposure time while the gas is passing through. If the length of the curved duct is the same as a straight tube would have been, the overall size of the assembly may be reduced from what it otherwise would have been. If the curved length is made longer while the size of the assembly is kept the same, the exposure time is increased for a more effective sterilization.

A process for using photocatalytic load reduction to extend reactive media filtration life is disclosed for an air purification system. The system consists of three methods of cleaning the air including a UV light, a photocatalyst, and an air purifier. Air first passes through a portion with the UV light and photocatalyst, and then through the purifier. Passing the air first through the UV light and photo catalyst before the purifier reduces the load on the purifier and thus allowing the purifier to operate and clean the air for an extended period of time as compared to the purifier alone.

The invention belongs to the field of eliminating pollutant gases. In particular, the invention belongs to the field of pollutant gas-absorbing material such as CO2, SO2, NOx and VOCs.

The present invention relates to a fresh composite or composite paste and a composite material comprising aggregates of recycled concrete, porous carbon, a binder and optionally water, as well as to the method for manufacturing the composite and the use thereof for sanitizing air (indoor or outdoor). The invention also relates to an article (for example, an anti-noise wall, a tunnel lining, an indoor decoration, an item of street furniture, etc.) comprising the composite according to the invention.

A method for the removal of mycotoxins from a space associated with a built environment is disclosed. The method may include one or more of the steps of: filtering air within the space using a first filter including a High-Efficiency Particulate Air (HEPA) filter and a second filter including a carbon filter; and, applying a cleaning product including a high alkaline product to one or more surfaces proximate the space.

Disclosed is an internal circulation type lampblack purifier. The internal circulation type lampblack purifier comprises a shell, an air inlet, an air outlet, an air inlet channel, an air outlet channel, a fan device, a mechanical grease separator, a gas purification device and a cooling device, wherein the air inlet and the air outlet are arranged on the shell; the mechanical grease separator is arranged at the air inlet or in the air inlet channel; and the cooling device is arranged at the air outlet and comprises a water supply pipe, water spray guide plates, a water mist baffle plate, a spray pipe and a water receiving tank, the spray pipe communicates with the water supply pipe, spray nozzles are arranged on the spray pipe and face the water spray guide plates, the water receiving tank is located below the water spray guide plates, and the water mist baffle plate is provided with blades at certain gaps. According to the internal circulation type lampblack purifier, the cooling device is arranged, so that the temperature of discharged gas is effectively reduced, high-temperature water vapor in the discharged gas is eliminated, and the influence of the high-temperature water vapor on the indoor environment is prevented.
