Abstract

The present invention relates to an ethylene disposal apparatus comprising: a plasma discharge part having an inlet and an outlet and being filled with an adsorbent; and an electrode part for generating plasma inside the plasma discharge part, wherein the adsorbent has a catalyst supported thereon. The present invention relates to an ethylene disposal method using the ethylene disposal apparatus, the method comprising the steps of: (a) injecting ethylene-containing gas into a plasma discharge part filled with the adsorbent; (b) applying voltage to the electrode part and generating plasma in the plasma discharge part, thereby degrading the injected ethylene; and (c) cooling the plasma discharge part.

Claims (13)

1. An ethylene disposal apparatus, comprising:

a facility for storing an agricultural product, wherein ethylene is generated in the facility;

a plasma discharge part having inlets and an outlet and filled with an adsorbent therein, and directly connected to the facility for storing an agricultural product through one of the inlets, wherein air is introduced into other inlet of the inlets; and

an electrode part configured to generate plasma inside the plasma discharge part,

wherein the adsorbent supports silver oxide (Ag 2 O) as a catalyst,

wherein ethylene generated in the facility for storing an agricultural product is reacted with oxygen of air and decomposed into carbon dioxide and water vapor through composite actions of the plasma and the catalyst in the plasma discharge part;

wherein the plasma discharge part further includes a coil having a conductive region formed at a predetermined area and formed to wrap around an outer surface of the plasma discharge part in the conductive region,

wherein the coil is made of a copper wire, an iron wire or an aluminum wire and comes in contact with a ground electrode,

wherein the adsorbent is formed in a spherical shape or pellet form and is zeolite 13X,

wherein the catalyst is supported on the adsorbent at a mass fraction of 1 to 10 wt% based on the weight of the adsorbent.

2. The ethylene disposal apparatus according to claim 1 , wherein the plasma discharge part is made of a quartz tube, a glass tube, an alumina tube or a ceramic tube.

3. The ethylene disposal apparatus according to claim 1 , wherein the electrode part extends into an inside passage of the plasma discharge part and is a metal rod arranged coaxially with the plasma discharge part.

4. The ethylene disposal apparatus according to claim 1 , wherein the electrode part is connected with a voltage supplying device configured to supply power to the plasma discharge part.
