Abstract
A zeolite catalyst capable of maintaining a high conversion of raw materials over a long period of time, and a method of producing a lower olefin stably over a long period of time using the zeolite catalyst is to be provided. A CON zeolite catalyst containing aluminum (Al) as a constituent element, wherein the CON zeolite catalyst has a ratio ((A/A)×100 (%)) of an integrated intensity area (A) of signal intensity in a range from 57.5 ppm to 70 ppm to an integrated intensity area (A) of signal intensity in a range from 45 ppm to 70 ppm is not less than 49.0% when analyzed byAl-MAS-NMR is prepared, and a lower olefin is produced by a MTO process using the zeolite catalyst.
