A lower olefin producing catalyst which has high olefin production efficiency and maintains its activity for a long period of time when lower olefins are produced from an oxygen-containing compound, which is a solid catalyst used in producing lower olefins from an oxygen-containing compound, includes a solid-state catalyst component containing an MFI-type zeolite, in which, at a position where the shortest distance to the outer surface is maximum among all positions inside a structure of the solid catalyst, the thickness defined as a distance twice the shortest distance from the point to the outer surface is in a range of from 0.1 to 2.0 mm, and a method for producing lower olefins.

Lower olefins producing catalyst and method for producing lower olefins using same

An alkaline-earth metal compound-containing zeolite catalyst composed of a composite material comprising at least a first component, a second component, and a third component. The first component is composed of at least one of zeolites selected from a group consisting of proton-type zeolites and ammonium type zeolites. The second component is composed of at least one of alkaline-earth metal compounds. The third component is composed of at least one selected from a group consisting of aluminum oxides, aluminum hydroxides, silicon oxides, silicon hydroxides, and clay minerals. The first component has a molar ratio of Si/Al of 10 or more and 300 or less. Content of the second component relative to the first component is 0.3 mass % or more and less than 10 mass % as alkaline-earth metal. Content of the third component relative to the first component is 15 mass % or more and 200 mass % or less.
