目前,对 A 型分子筛的需求日益增长,而利用天然资源制备分子筛既可节省化工原料,又能合理利用资源。故探索以天然资源为原料研制分子筛是有一定意义的。国内外均有使用高岭土、膨润土合成 A 型分子筛的报道。本文 At present, the demand for type A molecular sieves is increasing day by day. However, the use of natural resources to prepare molecular sieves can save chemical raw materials and make rational use of resources. Therefore, exploration of natural resources as raw materials to develop molecular sieve is of some significance. At home and abroad have used kaolinite, bentonite synthesis of A-type molecular sieve reports. This article
