Abstract

본 원은 메탄으로 부터 에틸렌 제조용 담지촉매, 그의 제조방법 및 그에 의한 에틸렌의 제조방법에 관한 것이다.The present application relates to a supported catalyst for producing ethylene from methane, a method for preparing the same, and a method for producing ethylene therefrom.

촉매는 일반식 MaPbS로 표시하며, 여기서 M은 Ru, Rh의 착화합물이며, S는 사용된 무기담체이다. a는 촉매중의 금속의 중량 백분율이고, b는 촉매중의 촉진제 금속의 중량 백분율이다.The catalyst is represented by the general formula M a P b S, 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 and b is the weight percentage of the promoter metal in the catalyst.

메탄, 질소 및 일반식 MaPbS(Ⅰ)의 촉매의 존재하에 가온, 가압하여 에틸렌을 제조한다. 본원에서는 에틸렌을 제조하는데 있어서 부산물이 전혀 생성되지 않으므로 생성물의 분리, 정제가 쉽고 여타의 기존공정에 비해 반응 온도가 낮으므로 에너지의 절약, 공정의 단순화, 생산에 소요되는 시간의 단축등의 아주 우수한 효과가 있다.Ethylene is prepared by heating and pressing in the presence of methane, nitrogen and a catalyst of the general formula M a P b S (I). 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 lower than that of other conventional processes, thus saving energy, simplifying the process, and reducing the time required for production. It works.
