PURPOSE: A method for preparing propylene with high selectivity is provided to improve high yields and the selectivity of propylene in a catalytic conversion reaction of a mixture including methanol or dimethylether and a diluted gas. CONSTITUTION: A method for propylene with high selectivity comprises a step of improving high yields and selectivity by introducing a crystalline H-Fe-ZSM-5 catalyst to a propylene conversion reaction. The catalyst is a crystalline H-Fe-ZSM-5 catalyst consisting of silicon(Si), aluminum(Al), iron (Fe), and oxygen(O) by introducing an iron(Fe) component to a framework of crystalline zeolite(H-ZSM-5). |
