Abstract
Description
[実験例1.実験材料]
本発明の実験例では、吸着剤にゼオライト(Cosmo Fine chemical)を使用した。より具体的に、4A、Y、13X、ベータ(beta)の総4種類のゼオライトを比較して、エチレンに対する吸着性能が一番優秀な13Xを触媒の支持体(吸着剤)に使用した。前記13X(Molecular Sieve 13X)の比表面積は、約500m2/gであった。
本発明の実験例を通じてエチレン処理装置を利用して農産物貯蔵施設のエチレンを除去した。
エネルギー収率(energy yield)とは、処理されたエチレンの量/投入された電気エネルギーを意味する。32ppmのエチレンを500min間吸着/蓄積させたとき、総吸着量は、18.7mgであり、20min(1200sec)間のプラズマ/触媒分解段階に投入された電気エネルギーは、17W×1200sec=20400J(20.4kJ)である。したがって、エネルギー収率は、0.92mg/kJである。本発明と異なり32ppmのエチレンを17Wで500min間連続して処理したときのエネルギー収率は、0.037mg/kJである。
図6の(a)は、エチレンのFTIRスペクトラムであり、(b)は、吸着されたエチレンをプラズマ/触媒作用により処理した時のFTIRスペクトラムを示した図である。図6に示したように、エチレンに起因した有害副産物の生成はほとんどなかった。これはプラズマ―触媒複合作用によりエチレンの中間酸化物がCO2やCOに酸化されたことを意味する。
