In this study, the development of novel zeolite catalyst for the efficient production of light olefins, which are widely utilized as a raw material of chemicals in the industrial field, from methanol has been studied. The physicochemicalsuch as the particle size and acid strength and catalytic properties of zeolite catalysts with a topology were successfully controlled by varying the structure of organic compounds and the concentration of the starting gel for the zeolite synthesis. In addition, new method for the zeolite synthesis was successfully developed without any organic compounds at shorter synthesis duration compared the conventional methods. In the conversion of methanol to light olefins, nanosized zeolites synthesized employing the novel method above exhibited a longer catalyst life compared with the zeolite with the same structure synthesized by conventional methods.
