Abstract
The invention discloses a modified corncob porous material and application thereof to cigarettes. The porous material is obtained by performing procedures of microwave expansion, crushing granulation, modification with a modifier, microwave expansion drying and the like on corncobs. The modified corncob porous material is added to a cigarette filter to prepare a binary composite filter which is applied to the cigarettes, wherein the addition of the modified corncob porous material is 18 to 52 percent based on the total weight of the filter. Actual application shows that components such as tar, nicotine, hydrogen cyanide, phenol and crotonaldehyde in cigarette smoke can be effectively reduced. The modified corncob porous material is convenient to operate and low in cost, and has broad application prospect.
