去する吸着剤に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an olefin adsorbent, and in particular, it is used to preserve the freshness and long-term preservation of fruits and vegetables. This invention relates to an adsorbent that removes hormones that have an effect on the body.

って吸着しているものを追い出す必要もあり、不都合で
あるという問題点があった。Conventional naturally produced Oya stone and zeolite have too small adsorption capacity for olefins, so synthetic zeolites are able to absorb olefins,
In particular, the ethylene adsorption method is affected by moisture (moisture in the atmosphere is preferentially and strongly adsorbed), which interferes with the adsorption and removal effect of ethylene. Therefore, the adsorption and removal of olefins using conventional adsorbents has the disadvantage of requiring the use of large amounts of adsorbent or the need for repeated and frequent regeneration treatments. In this case, there was a problem in that it was necessary to remove the adsorbed material from the front, which was inconvenient.

本発明のオレフィン吸着剤のオレフィンの吸着機構につ

(4) The above reaction is a well-known reaction that has been put to practical use by subjecting acetaldehyde from ethylene to IL reaction, but since the olefin adsorbent of the present invention contains a super strong acid (sulfuric acid treated carrier), the Accelerates reactions at room temperature and with high performance.
すなわちエチレンＣＨ２＝ＣＬが超強酸表面のＨΦと結
合して吸着するので、この反応が促進される。That is, since ethylene CH2=CL binds to and adsorbs HΦ on the surface of the super strong acid, this reaction is promoted.

でオレフィンの吸着容量が著しく増加する。Furthermore, as can be seen from the above reaction, since the presence of water is a necessary condition, there is no reduction in the adsorption capacity for olefins due to co-adsorption of water, unlike in conventional adsorbents. Acetaldehyde is produced, which can be recycled as it is soluble in solvents such as acetone. Furthermore, since the carrier is a superacid, the adsorption capacity for olefins is significantly increased.
