MTW型沸石的制造方法
摘要：
本发明提供一种MTW型沸石的制造方法。本发明是一种使包含二氧化硅源、氧化铝源、碱源及水的反应混合物、与沸石的晶种反应而制造MTW型沸石的方法。所述反应混合物是使用在仅由所述反应混合物合成沸石时，所合成的所述沸石包含MFI型沸石的组成的反应混合物。所述晶种是使用SiO2/Al2O3比为8～50、且不含结构导向剂的β型沸石。以相对于所述反应混合物中的二氧化硅成分0.1质量％～20质量％的比例添加所述晶种至所述反应混合物中，将添加了所述晶种的所述反应混合物在100℃～200℃下密闭加热。所述方法不使用结构导向剂且可以廉价地制造MTW型沸石。
摘要（英）：

Provided is a method for producing an MTW-type zeolite. The reaction mixture contains a silica source, an alumina source, an alkali source, and water is reacted with a seed crystal of a zeolite to produce an MTW-type zeolite. The reaction mixture has a composition, which makes a synthesized zeolite contain an MFI-type zeolite when the zeolite is synthesized solely from the reaction mixture, is used. As the seed crystal, a beta-type zeolite which has a ratio of SiO2/Al2O3 of 8 to 50 and does not contain a structure direction agent is used. The seed crystal is added to the reaction mixture, in a proportion of 0.1% by mass to 20% by mass based on a silica component in the reaction mixture. The reaction mixture to which the seed crystal has been added is heated at 100° C. to 200° C. in a sealed state.
