Zeolite beta materials were carefully prepared, and then FCC catalysts were fabricated based on them.Their catalytic cra......

A suspension of highly monodisperse zeolite beta nanocrystals with diameter of ...

对β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.......

在连续流动反应装置上研究了β沸石分子筛上正戊醇的酯化反应。经５００℃焙烧后的β分子筛对该反应有较好的催化作用。在β分子筛上，适宜......

以异丙苯和正十六烷裂解两种特征探针反应对空气中焙烧脱铝、酸洗脱铝与脱铝-再铝化的β沸石样品的活性进行表征,并与正丁胺滴定的......

采用电子衍射，Ｘ－射线衍射，高分辩电子显微术，模拟像计算确定β－沸石点阵参数，即β－沸石属于单斜晶系：αｍ＝ｂｍ＝１．７４ｎｍ，ｃｍ＝１．４３ｎｍ，βｍ＝１１４．°。首次拍摄到可清楚分辨β－沸......
