Abstract
A method for preparing a NaY molecular sieve having a high silica-to-alumina ratio, wherein deionized water, a silicon source, an aluminum source, an alkali source, and ILs as a template agent are mixed to obtain an initial gel mixture; the initial gel mixture is maintained at a proper temperature and aged, then fed into a high pressure synthesis kettle for crystallization; the solid product is separated and dried, to obtain the NaY molecular sieve having a high silica-to-alumina ratio, wherein the ILs is a short-chain alkylimidazolium ionic liquid, the template agent is less volatile, and the resultant high-silicon Y molecular sieve has a high crystallinity and a silica-to-alumina ratio of 6 or more.
