Abstract:
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.
