The procedure is similar to the one used for single-crystal x-ray diffraction but on crystals million times smaller.34 Despite the large number of already existing zeolite framework topologies and compositions, it is not always possible to find the ideal structure for a certain application. Thus,...
Various types of zeolites can be produced from CFA, among them zeolite-A (Zt-A), zeolite-X (Zt-X) and zeolite Na-P1 (Na-P1) are industrially very important because of uniform pore size, catalytic activity and high cation exchange capacity (Chang and Shih, 2000, Kunecki et al., 2020...
但是目前已工业化的,具有经济意义的只有几种,其中产量最多的占人工合成沸石总量的99%的是4A沸石,其次是Y型和X型沸石。 沸石矿物的晶体具有架状结构。在架状骨干中存在着由[(Si,Al)O4]四面体组成的环(如由四个四面体组成的“四元环”、六个四面体组成的“六元环”,以及“五元环”、“八元环”、“十二元环...
