Therefore, the content weight of the fibrous activated carbon is reduced to less than 80%, and the content weight of the fibrous activated carbon is reduced due to the reinforcement. Therefore, there has been a problem that the original functionality of the fibrous activated carbon is reduced.

In this case, when collecting and regenerating the solvent by exposing it to an atmosphere of heated steam and exposing it to a solvent adsorption device, use a metal net. In addition, it is possible to avoid excessive corrosion damage, and also to prevent shrinkage deformation such as a plastic mesh, to exhibit its adsorption performance well over a long period of time, and to provide a product excellent in heat resistance.

させることが可能になった。<Effects of the Invention> As is apparent from the above description, according to the present invention, a net is sandwiched between the first and second pitch-based fibrous activated carbon nonwoven fabrics, and a pitch-based fibrous activated carbon nonwoven fabric is formed using the mesh. Because of the reinforcement and retention, the pitch-based fibrous activated carbon nonwoven fabric can be exposed on the entire outer surface of the obtained felt processed product, and the pitch-based fibrous activated carbon nonwoven fabric inherently has no effect on the reinforcement structure It is now possible to demonstrate the functions that are used 100%.

るようになった。In addition, pitch-based fibrous activated carbon nonwoven fabric has fine pores on the surface of carbon fiber, and its strength is very weak, so if it is not handled carefully, damage such as tearing is likely to occur,
According to the present invention, since the fiber is reinforced by the net due to the entanglement of a part of the fiber, the obtained felted product has a high strength as a whole and can be easily handled. Even in such a case, it is not necessary to use a special holding tool separately, and even if a holding tool is used, the configuration of the holding tool can be simplified. Cost can be reduced, and the economy can be improved.

なった。In addition, since the mesh is provided with a mesh having an opening ratio of 80% or more, when used in a solvent adsorption device, etc., the pressure loss due to the ventilation can be reduced, and the adsorption capacity of the pitch-based fibrous activated carbon nonwoven fabric can be sufficiently exhibited. Now you can do it.

ず、溶剤ガスを良好に吸着できる。In addition, the first pitch-based fibrous activated carbon nonwoven fabric having a small specific surface area has a small pore radius and a large adsorption power, while the second pitch-based fibrous activated carbon nonwoven fabric having a large specific surface area has a large pore radius and has a large adsorption radius. Since the amount becomes large and the solvent gas mixed with the impurities can be adsorbed in a large amount without being hindered by the impurities as a whole, the solvent gas can be satisfactorily adsorbed regardless of the concentration.
