The present invention relates to a catalyst for preparing a light olefin, a preparation method therefor, and a method for preparing a light olefin by using same, and can provide a catalyst for preparing a light olefin, a preparation method therefor, and a method for preparing a light olefin by using same, the catalyst comprising a porous zeolite, a clay, an inorganic oxide binder, and AgO and POwhich are supported in the pores and/or on the surface of the porous zeolite.

Catalyst for preparing light olefin, preparation method therefor, and method for preparing light olefin by using same

The present invention relates to a method for preparing ZSM-5 zeolite. The present invention can provide a method for preparing ZSM-5 zeolite comprising the steps of: preparing a first solution in a solution state by heating a mixture comprising a silica source, an alumina source, a neutralizing agent and a crystalline ZSM-5 nucleus; preparing a reaction mother liquid by mixing a second solution comprising salts into the first solution; and continuously crystallizing by continuously supplying the reaction mother liquid to a hydrothermal synthesis reactor, wherein formula [1] below is satisfied.0.20&#x2264;&#x2264;0.40&#x2003;&#x2003;Formula [1]
