Micro-mesoporous egg yolk-shell composite molecular sieve, preparation method of micro-mesoporous egg yolk-shell composite molecular sieve, and cigarette

The invention provides a preparation method of a micro-mesoporous egg yolk-shell composite molecular sieve. The micro-mesoporous egg yolk-shell composite molecular sieve provided by the invention sufficiently uses a cavity of an egg yolk-shell structure; the pore passage loss can be effectively avoided; the structure advantages of various pore passes of mesopores and micro pores can be simultaneously realized; harmful gas molecules with different sizes can be effectively adsorbed; the cigarette harm is reduced; the obvious adsorption effect is achieved on harmful substances, particularly phenol, crotonaldehyde and the like in the smoke gas of the cigarette. 本发明提供了种微介孔蛋黄-壳复合分子筛的制备方法。本发明所提供的微介孔蛋黄-壳复合分子筛，充分利用蛋黄-壳结构的空腔，可有效避免孔道的损失，并且能够同时发挥介孔和微孔多种孔道的结构优势，可以有效地吸附不同大小的有害气体分子，降低卷烟的危害性。对卷烟烟气中的有害物质特别是苯酚、巴豆醛等具有显著吸附效果。
