水热稳定性 meaning in Chinese
hydrothermal stability
Examples
- The synthesis and hydrothermal stability of aluminosilica molecular sieves al - mcm
41的合成与水热稳定性评价 - The suitable steaming and support treatment on zeolite beta can obviously increase the hydration activity of catalysts , and the introduction of sillica enhances the steaming stability of zeolite beta
对沸石进行水热处理和不同粘合剂改性,能提高其丙烯水合反应活性;氧化硅的引入能明显提高催化剂的活性和水热稳定性 - It is discovered that existence of small amount of n - butyl alcohol in mesoporous zeolite synthesis system can not only modify ordered degree of formation of mesoporous zeolite , which improves hydrothermal stability of it , but also help to attain much smaller , nearly nanometer , grain of mesoporous zeolite
研究发现,少量正丁醇的存在能改善介孔分子筛形成过程的有序度,并使其水热稳定性得到提高,同时合成产物的粒度更小,趋近纳米颗粒。 - The smaller the ratio of nh3 / teos is more helpful for the synthesis of samples . the contraction from calcination of samples obtained in eda medium is proporational to the ratio of eda / teos at room temperature . the samples obtained in mixed basic media ( naoh / tea ) have thicker wall and more thermal stability than in naoh medium , but pore size is smaller correspondingly
氨水介质中, nh _ 2 teos值在( 8 , 25 )之间越小,越有利于mcm - 41的室温合成;室温条件下eda介质中得到样品的烧成收缩量与eda teos的值成正比;与naoh介质相比,混合介质( na0h三乙醇胺)中水热合成的样品具有较厚的孔壁,有着更好的水热稳定性,但同时孔径相应较小。
