Description of the Related Art Conventionally, as an adsorption element having a large number of air passages, there are a combination of a lattice-like sheet or the like and an embossed sheet processed into an uneven shape. The shape which effectively uses is preferably a honeycomb shape. Therefore, the outline of the present patent will be described below using a honeycomb-shaped suction element as an example. As a honeycomb-shaped adsorption element, an organic binder such as PVA and an organic fiber and / or an inorganic sheet and an adsorbent sheet obtained by mixing and forming an adsorbent are used by a honeycomb molding machine, and an organic binder is used as an adhesive for honeycomb molding. And honeycomb-shaped articles. This adsorbing element can increase the content ratio of the adsorbent by using organic fibers having a low bulk density and a high beating degree and using an organic binder such as PVA, and thus the organic solvent can be used. It is possible to remove bad odor components such as high adsorption. However, with an organic binder such as PVA and an organic binder for honeycomb molding,
When heat treatment is performed in a regeneration step or the like, when the temperature of the adsorbing element suddenly rises to about 300 ° C., the adsorbing element exhibits thermal decomposability, and there is a risk of ignition and combustion of the element, causing a significant decrease in strength. Problem, that is, the heat resistance is poor. On the other hand, as such a high heat-resistant honeycomb-shaped adsorption element, there is an inorganic adsorption element obtained by impregnating a honeycomb-shaped inorganic element made of an inorganic binder and an inorganic fiber with a mixed slurry liquid of an adsorbent and an inorganic binder and drying it, Since the adsorbing element is made of an inorganic material that does not exhibit thermal decomposition, the adsorbing element itself does not have thermal decomposability. However, the adsorbent is inferior in supportability, and the element may contain a necessary amount of adsorbing material. There is a problem that it is difficult and the adsorption performance of malodorous components such as organic solvents is low. Further, there is a problem that the adsorbent easily falls off.

It is a fiber with a thermal decomposition temperature of 300 ° C or more and excellent heat resistance. It is desirable that the fibers are fibrillated for high loading of the adsorbent (A). If the thermal decomposition temperature is lower than 300 ° C., ignition, combustion, and a remarkable decrease in strength cannot be avoided at the high temperatures encountered during the adsorption / desorption operation. Specifically, it is a fiber made of aramid, metaaramid, polybenzimidazole (PBI), polybenzoxazole (PBO), polyimide, polyamideimide, and polyetherketone. The organic component (B) has a melting point or thermal decomposition temperature of 300 in addition to the heat-resistant organic component (B-1).
Preferably, it contains a substance below ℃. The low-temperature decomposable organic component (B-2) has a function of causing the adsorbent to support the adsorbent (A) at a high ratio during the production of the adsorbent.
