| titleOfInvention | MWW molecular sieve, its preparation method and application, catalyst and method for deolefinization of hydrocarbon oil |
| abstract | The invention relates to the field of deolefinization of hydrocarbon oil, and discloses a MWW molecular sieve, its preparation method and application, a catalyst and a method for deolefinization of hydrocarbon oil. The acid content of the molecular sieve is not less than 0.9mg NH 3 /100mg. The preparation method of the molecular sieve comprises: mixing silicon source, aluminum source, alkali source, templating agent and water at 0-15°C, then performing hydrothermal treatment and roasting, wherein the silicon source, aluminum source, alkali source, template agent and water The molar ratio is 10:0.2‑2:5‑30:0.5‑10:20‑300, wherein the silicon source is calculated as SiO2 , the aluminum source is calculated as Al2O3 , and the alkali source is calculated as OH‑ . The catalyst containing the MWW molecular sieve provided by the invention has a large heap ratio, is used in the process of reducing olefins from aromatic raw materials, reduces the bromine index of raw materials by at least 60%, and has good stability. |
