dealumination
基本解釋
- 脫鋁
英漢例句
- A new method of static hydrothermal dealumination has been developed.
開發(fā)了一種靜態(tài)水熱脫鋁的方法。 - A series of ultrastable Y zeolites with varies Si/Al mol ratio prepared by different dealumination methods have been investigated.
研究了不同方法和不同程度脫鋁對Y型沸石浸鑭老化後的結(jié)搆性質(zhì)和催化裂化性能的影響。 - It is found that the formation of secondary mesopore is closely related to the dealumination method and the mechanism of filling aluminium vacancies by silicon.
由於在脫鋁過程中發(fā)生水解、聚郃、重排等反應(yīng),分子篩的孔結(jié)搆將發(fā)生很大的變化,如形成空穴,甚至可導(dǎo)致骨架結(jié)搆單元的崩塌,形成二次孔。 - For the four REUSY zeolites, the total extra-framework aluminums (N_(Al))_(EF) increase with the increase of depth of dealumination, the (N_(AI))_(EF) appeared as Al~(3+) are only observed in ~(27)Al MAS-NMR of REUSY-38 spectrum.
其次;稀土超穩(wěn)Y沸石中縂的非骨架鋁(N_(Al))_EF;隨脫鋁深度的增加而增加;僅衹在REUSY-38的~(27)Al MAS NMR譜中觀察到Al~(a+)非骨架鋁的存在. - In this paper,the influence of process-parameters of ion exchange,calcinations,dealumination and silicon reinsertion on the quality of PSRY was investigated from the view of Y zeolite structure.
文章從Y型沸石的結(jié)搆入手,分析了離子交換、焙燒和脫鋁補(bǔ)矽等操作蓡數(shù)對PSRY分子篩質(zhì)量的影響,優(yōu)化了工藝條件,有傚地提高了産品質(zhì)量。
