Hydrothermal Synthesis of 4 A Zeolite from Kaolinite in Coal Measures and Studies of Its Properties

摘要

In this thesis, a kind of high quality 4A zeolite has been synthesized by using kaolinite in coal measures as raw materials. The whole reactive process of calcined kaolinite with alkaline solution making for 4A zeolite are studied by determining calcium ion exchange capacity and by XRD, SEM. The technological parameters, which are fit for requirement detergent aid, were proposed.
