Production for synthesizing high-content NaY molecular sieve from kaolin atomized microball

Synthesis of high-content NaY molecular sieve from kaolin spray micro-sphere is carried out by taking kaolin as raw materials, adding into functional components, removing ion water to obtain mixed size, spray drying to obtain kaolin micro-sphere, calcining at 700i½1000iOC, mixed crystallizing by guiding agent, washing and drying by filter cake, or high-temperature baking one part of spray micro-sphere with 20i½110a–m to obtain high-temperature calcined clay, baking another part of micro-sphere at low temperature to obtain biskaolin, mixing the two baked kaolin, and crystallization reacting under hydrothermal condition to obtain crystallized product containing NaY molecular sieve in proportion of NaY=46i½60% and silicon:aluminium=3.5i½5.5.
