To provide a zeolite type catalyst capable of efficiently manufacturing a lower olefin by suppressing the formation of aromatic components and having high durability under a high temperature steam atmosphere, its manufacturing method and a method of manufacturing the lower olefin using the zeolite type catalyst.
The catalyst for manufacturing the lower olefin includes crystalline aluminosilicate on which an alkaline earth metal and phosphorus are supported and is characterized in that the alkaline earth metal and phosphorus are each supported on the crystalline alminosilicate in separate processes. The method of manufacturing the catalyst for manufacturing the lower olefin is characterized in that the alkaline earth metal and phosphorus are each supported on the crystalline aluminosilicate in the separate processes when the catalyst for manufacturing the lower olefin is manufactured by supporting the alkaline earth metal and phosphorus on the crystalline aluminosilicate. Further, the method of manufacturing the lower olefin is characterized by using the catalyst for manufacturing the lower olefin.
