본 발명은 2 내지 5개의 탄소 원자를 갖는 알칸의 탈수소화로부터 올레핀을 생성하기 위한 촉매, 및 상기 촉매를 사용하여 올레핀을 제조하는 방법에 관한 것이며, 여기서, 상기 촉매는 120 초과의 실리카 대 알루미나 (SiO/AlO) 비 및 0.3 내지 5 wt% 범위의 10족 금속(들)을 갖는 계층적 제올라이트 나노시트(hierarchical zeolite nanosheet)를 포함한다. 본 발명에 따른 촉매는 높은 전구체 전환 수율 및 높은 올레핀 선택도를 갖는다. The present invention relates to a catalyst for producing olefins from dehydrogenation of alkane having 2 to 5 carbon atoms and a method for producing olefins using said catalyst, wherein said catalyst comprises a hierarchical zeolite nanosheet having a silica to alumina (SiO2/AI2O3) ratio more than 120 and group X metal(s) in a range of 0.3 to 5% by weight. The catalyst according to the conversion of precursor to yields and high olefins selectivity.
