MTO catalyst and applications with a high propylene selectivity

MTO catalyst having a high propylene selectivity, characterized in that the catalyst has ITH topology, which includes a framework elements, silicon, germanium, aluminum, oxygen, wherein Al2O3: SiO2 molar ratio of 1: 20-1000, SiO2 : of GeO2 molar ratio of 12-500: 1. The present invention has a high propylene selectivity, the propylene / ethylene ratio by mass of advantages.
