SYNTHESIS OF CRYSTALLINE LONG-RANGED ORDERED MATERIALS FROM PREFORMED AMORPHOUS SOLIDS

摘要

crystalline or long-distance rules substances (crystalline or long-ranged ordered material; CLROM ) , for example, a composite of zeolite and non- zeolitic molecular sieve is disclosed. The macro- particle size complex is as desired in commercial use (e.g. , an average particle size of greater than 0.1 mm ) , and has all of the improved functionality. Such complexes will typically amorphous materials, such as the size of the solid amorphous silica -alumina particles in accordance with the transition to CLROM. Depending on certain embodiments, all or substantially all of the amorphous material (for example , more than 99%) is converted to CLROM, has essentially the entire macroscopic material can have the desired functionality of CLROM as a catalyst or adsorbent . ;
