Abstract

본 발명을 에틸렌과 산소 또는 산소함유 기체의 기상 접촉 부분산화반응에 의하여 산화에틸렌을 제조하는데 사용하는 은 담지 촉매에 관한 것으로서, 담체 성형시에 산화니오비움을 담체 전체 무게에 대하여 5~40중량%를 첨가하여 제조된 것을 특징으로 하며, 또한 성형된 담체에 수산니오비움을 도핑하여 담체를 처리한 것을 특징으로 한다. 본 발명에 따른 산화에틸렌 제조용 은 담지 촉매는 활성 및 선택성이 매우 높고, 촉매의 수명도 길다.The present invention relates to a silver supported catalyst which is used to prepare ethylene oxide by gas phase catalytic partial oxidation of ethylene and oxygen or oxygen-containing gas. It characterized in that it is prepared by the addition, and characterized in that the carrier is treated by doping niobium hydroxide to the molded carrier. The silver supported catalyst for producing ethylene oxide according to the present invention has very high activity and selectivity, and has a long service life.
