    摘要: The invention relates to the use of a catalyst based on crystalline aluminosilicates for the conversion of oxygenates to lower olefins, the catalyst having an SiO2/Al2O3 molar ratio of 20 to 200 and being modified with 0.1% to 10% by weight of readily oxidant metal (calculated as the corresponding metal oxide) and/or with 0.05% to 5% by weight of cerium (calculated as Ce2O3), and also to an associated method.
