Abstract

본원은 촉매 및 그 제조방법 및 제조된 촉매를 사용하여 연속식 반응공정에서 메탄으로 부터 에틸렌을 제조하는 방법에 관한 것이다.The present application relates to a catalyst, a method for preparing the same, and a method for preparing ethylene from methane in a continuous reaction process using the prepared catalyst.

촉매의 일반식은 MaS로 표시되며, 여기서 M은 Ru, Rh의 착화합물이며, S는 사용된 무기체 담지체이다. a는 촉매중의 금속의 중량 백분율이다.The general formula of the catalyst is represented by MaS, where M is a complex of Ru, Rh, and S is the inorganic carrier used. a is the weight percentage of the metal in the catalyst.

메탄, 질소, 촉매의 존재하에 가온, 가압하에서 에틸렌을 제조하였다.Ethylene was prepared under warming, pressurization in the presence of methane, nitrogen, and catalyst.

본원에서는 에틸렌을 제조하는데 있어서 부산물이 전혀 생성되지 않으므로 생성물의 분리, 정제가 쉽고, 여타의 기존 공정에 비해 반응온도가 저하되므로 에너지의 절약, 공정의 단순화, 생산에 소요되는 시간의 단축등의 아주 우수한 효과가 있다.Since no by-products are produced in the production of ethylene, it is easy to separate and purify the product, and the reaction temperature is lowered compared to other conventional processes. Excellent effect.
