| titleOfInvention | Zeolite-containing catalyst and method for producing lower olefin |
| abstract | Protons that have high hydrothermal stability without modification by adopting zeolite itself with high hydrothermal stability, or that can dramatically improve hydrothermal stability by combining with zeolite A type MFI structured zeolite is provided. It includes a proton-type MFI zeolite is at least one of the conversion reaction catalyst to lower olefins of the hydrocarbon feed containing olefins having a carbon number of 4-6 that are exposed to steam during catalyst regeneration, the zeolite 27 Al- Peaks derived from Al in the framework of the zeolite, which are found in the chemical shift range of 45 ppm to 65 ppm of the NMR spectrum obtained by MAS-NMR, are drawn with reference lines for 45 ppm and 65 ppm, and the X-axis at 55 ppm at the center ( A zeolite-containing catalyst, wherein the area of the low chemical shift region of 45 ppm to 55 ppm occupies 50% or more of the entire area of 45 ppm to 65 ppm when divided into two parts in the vertical direction with respect to (chemical shift). |
