Micro-mesoporous core shell composite molecular sieve for reducing the harmful composition contained in a cigarette and a producing method thereof

摘要

The present invention discloses a micro-mesoporous core shell composite molecular sieve for reducing harmful components of tobacco, and a method for producing the same. The method comprises the steps of feeding a template to a solution having a water content of 1: 1 to 4: 3, Tetraethoxysilane is added to the zeolite molecular sieve in an amount of 1 to 1.5 times the mass of the zeolite molecular sieve. The mixture is stirred at room temperature for 24 to 48 hours and the template is extracted with ethyl alcohol at room temperature To obtain a mesoporous-microporous core shell composite molecular sieve material. In the manufacturing method of the present invention, the high temperature calcination is omitted for extracting the template directly with ethyl alcohol, the manufacturing process is simpler, the operation and facility requirements are more simple, the price is low, the application is good, and the micro-Application of the molecular sieve to a bicomponent composite filter rod has a remarkable adsorption effect on harmful substances in cigarette smoke, especially on phenol.;
